What are the features of XPS insulation board?

XPS insulation board is extruded polystyrene insulation board, which is made of polystyrene resin as raw material plus other raw materials and polymers, through heating and mixing while injecting catalysts, and then extruded and extruded to form a rigid foam board made of rigid foam board Its scientific name is extruded polystyrene foam for insulation (referred to as XPS), XPS has a perfect closed-cell honeycomb structure, this structure makes XPS board have extremely low water absorption (almost no water absorption), low thermal conductivity, high compressive resistance, Anti-aging (almost no aging decomposition phenomenon under normal use). Performance characteristics:

1. Excellent thermal insulation, with the characteristics of high thermal resistance, low linearity and low expansion ratio, the closed cell rate of its structure has reached more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, ensuring the durability and stability of its thermal insulation performance, compared with the closed cell rate of 80% of foamed polyurethane, the leading edge is self-evident. Practice has proved that the thermal insulation effect of 20mm thick XPS extruded insulation board is equivalent to 50mm thick expanded polystyrene and 120mm thick cement perlite. Therefore, this material is currently the best choice for building insulation.

2. Excellent high strength and compressive resistance, due to the special structure of XPS board, its compressive strength is extremely high, impact resistance is very strong, according to the different models and thickness of XPS, its compressive strength reaches more than 150 500kpa, can withstand the ground load of various systems, and is widely used in geothermal engineering, highways, airport runways, square ground, large cold storage and car interior decoration insulation and other fields.

3. High-quality hydrophobic and moisture-proof water absorption rate is an important parameter to measure insulation materials. After the insulation material absorbs water, the thermal insulation performance decreases, and in the case of low temperature, the inhaled water is very easy to freeze, which destroys the structure of the insulation material, so that the compressive resistance and thermal insulation performance of the board decreases. Because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable and has no gaps, which solves the problems of water leakage, penetration, frosting, condensation and other materials.

4. The completely closed-cell foaming chemical structure and honeycomb physical structure of the XPS board with light texture and easy to use make it have the characteristics of light weight and high strength, easy to cut and transport, and not easy to break, easy to install.

5. Stability, anti-corrosion for a long time in use, no aging, no decomposition, no harmful substances, its chemical properties are extremely stable, will not be degraded due to water absorption and corrosion, so that its performance declines, in the high temperature environment can still maintain its superior performance, according to the relevant information, XPS extruded insulation board even if used for 30 40 years, can still maintain excellent performance, and will not decompose or mildew, no volatilization of toxic substances.

6. The environmental performance of the product XPS board has been tested by the relevant state departments to have stable chemical properties, no volatile harmful substances, harmless to the human body, and the production raw materials are environmentally friendly materials, which do not produce any industrial pollution. The product is an environmentally friendly building material.

At the same time as EPS as a thermal insulation board, but in the performance of the great characteristics, the difference between the two: EPS is the abbreviation of expanded polystyrene foam, EPS external thermal insulation system is a special cement, board, glass fiber mesh cloth and decorative coating composed of a new type of construction system that integrates wall insulation and decorative functions. The new EPS external thermal insulation finishing system is a simple and easy external thermal insulation technology, which has the outstanding characteristics of simple and fast construction, convenient design, short cycle and small amount of drawing.

XPS insulation board is a rigid polystyrene foam board produced by direct extrusion. It is an environmentally friendly material with excellent performance such as high pressure resistance, moisture-proof, non-breathable, non-water absorption, corrosion resistance, low thermal conductivity, light weight, and long service life. The performance of extruded plastic board is stable and not easy to age.

It can be used for 30-50 years, with excellent moisture resistance, and can still maintain low thermal conductivity in the environment of high water vapor pressure. Because it has a closed-cell performance structure and its closed-cell rate of 99%, it has good thermal insulation performance.

XPS insulation board according to its performance of the application field: building roof insulation, steel structure roof, building wall insulation, building ground moisturizing, square ground, ground frost heave control, air conditioning ventilation ducts, etc.; The ground moisture-proof insulation layer is widely used in the moisture-proof bottom layer of various buildings, and the roadbed laying under the roadbed of highways, railways and airport runways in alpine areas can control the thermal expansion and contraction of floor tiles, and has an excellent structural load-bearing effect; Interior decoration, advertising boards, widely used in interior decoration, ceilings, soundproof walls, sandwich door filling materials, to play heat insulation, sound insulation, moisturizing, weight reduction and other effects. The board is made with a fireproof agent added during the production process, so it is not flammable.

It can also be widely used in advertising companies to produce various types of advertising billboards.

Hello dear, the difference between SXPS and XPS insulation board is: polystyrene board (SXPS) is a foam material with a closed-cell structure made of polystyrene resin as the main ingredient, through foaming and molding. Extruded board (XPS) is a rigid foam material with a closed-cell structure made of polystyrene resin or its copolymer as the main component, adding a small amount of additives, and extrusion by heating.

XPS air conditioning insulation board is an extruded polystyrene thermal insulation board, which is made of polystyrene resin as raw material plus other raw materials and polymers, injected with catalyst while heating and mixing, and then extruded and extruded to form a rigid foam board, its scientific name is extruded polystyrene foam for thermal insulation.

FAE-A grade fireproof honeycomb insulation board is a new type of thermal insulation material that is improved on the basis of traditional molded polystyrene foam board, so as to achieve Class A flame retardant effect.

XPS has a perfect closed-cell honeycomb structure, which makes the XPS board have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, and aging resistance (almost no aging decomposition phenomenon under normal use).

EPS insulation board not only continues the advantages of small thermal conductivity, good thermal insulation effect and light weight of traditional EPS foam board, but also makes up for the shortcomings of poor flame retardant effect of traditional EPS foam board, and overcomes the problem of heavy and high quality of similar flame retardant effect materials on the market.

XPS insulation board scope of application.

1. Building roof insulation, steel structure roofing, building Lisheng cave wall insulation, building ground moisturizing, square ground, ground frost heave control, air conditioning ventilation ducts, etc.

2. The ground moisture-proof insulation layer is widely used in the bottom layer of various buildings to prevent moisture, and the roadbed of roads, railways and airport runways in alpine areas can control the thermal expansion and contraction of floor tiles, and has an excellent structural load-bearing effect.

3. Interior decoration and advertising boards are widely used in interior decoration, ceilings, soundproof walls, and sandwich door filling materials, which can play the effects of heat insulation, sound insulation, moisturizing, and weight reduction. The board is made with a fireproof agent added during the production process, so it is not flammable. It can also be widely used in advertising companies to produce various types of advertising billboards.

Polystyrene board (EPS) is a foam material with a closed-cell structure made of polystyrene resin as the main ingredient through foaming and molding.

Extruded board (XPS) is a rigid foam material with a closed-cell structure made of polystyrene resin or its copolymer as the main component, adding a small amount of additives, and extrusion by heating.

Features of EPS vs XPS:

The thermal conductivity of XPS is smaller than that of EPS, and has the characteristics of high thermal resistance, low linearity and low expansion ratio, and the closed cell rate of its structure reaches more than 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring the durability and stability of its thermal insulation performance, compared with the closed cell rate of 80% of EPS, the leading edge is self-evident.

According to the national standard for testing (100 100 original thickness, 70 under 48h), the deformation of the XPS currently used in China (including foreign companies) is about , and the EPS is within, so the protective mortar and coating outside the building external insulation system using XPS board are easy to crack.

X-ray photoelectron spectroscopy (XPS) is an advanced analytical technique in the microscopic analysis of electronic materials and components, and it is often used in conjunction with Auger electron spectroscopy (AES).

Because it can more accurately measure the inner electron binding energy of atoms and their chemical shifts than Auger electron spectroscopy, it not only provides information on molecular structure and atomic valence state for chemical research, but also provides information on the elemental composition and content, chemical state, molecular structure and chemical bonds of various compounds for the study of electronic materials.

EPS is a foam material with a closed-cell structure made of polystyrene resin as the main ingredient through foaming and molding. XPS is a rigid foam material with a closed-cell structure made of polystyrene resin or its copolymer as the main component, adding a small amount of additives, and extrusion by heating.

The main feature is good thermal insulation performance, remarkable energy-saving effect, EPS polystyrene insulation system, is a set of thermal insulation, heat insulation, waterproof, decorative performance as one of the system.

EPS board (also known as benzene board, foam board) is commonly white, with about 4 6mm foam particles, and the friction is that the particles will fall. The strength is low, and it will deform slightly when pressed hard.

XPS, extruded board. It can be made in a variety of colors. The strength is high, and it can stand on people and deform slightly. The particles are fine.

As you can see. The building in the modern construction project is higher and higher, the better the materials are used, the high-rise building will be affected by the wind in addition to the influence of the wind, but also by the influence of temperature, at an altitude of two or three hundred meters, the temperature is generally much lower than the ground, so how to do a good job of thermal insulation measures for the upper part of the high-rise building is a problem that is not smiling and relaxed. Under the urging of all aspects of demand, the application of XPS insulation board was born, and he had to appear, which solved the problem of insulation of high-rise stairs at the same time, the application of XPS insulation board also involved all aspects.

So what kind of material is XPS insulation board? I believe that many people want to know the same answer to this question, and I will answer it here.

What kind of material is XPS insulation board.

XPS is an extruded polystyrene insulation board, which is a polystyrene resin as a raw material, and other raw materials and polymer-containing materials, through heating and mixing at the same time injected with a catalyst, and then extruded to form and manufacture rigid foam board. Its scientific name is extruded polystyrene foam insulation (XPS for short), XPS has a perfect closed-cell honeycomb structure, which makes the XPS board have extremely low water absorption (almost no absorption), low thermal conductivity, high compressive strength, and aging resistance (almost no aging decomposition phenomenon in normal use). Because of the special structure of the XPS board, its compressive strength is high, the impact resistance is strong, which depends on its compressive strength of the size and thickness of the XPS up to 150 500kpa above the ground can withstand the load of various systems, widely used in thermal projects, highways, airport runways, square ground, large cold storage insulation and interior decoration and other fields.

Good stability, good corrosion resistance: long-term use, not easy to age, decomposition, no harmful substances, extremely stable, will not cause corrosion of chemical properties due to water absorption and degradation performance decreases, at high temperature still maintain its superior performance, according to information, XPS extruded insulation board even if used for 30 40 years, can still maintain excellent performance, and will not decompose or mildew, no volatilization of toxic substances. The water absorption of XPS insulation board is also very good, and the water absorption rate is an important parameter to measure its insulating material.

The insulating properties of the absorbed insulating material decrease, and after a lower temperature, the inhaled water can easily freeze, destroying the structure of the insulating material so that the compression plate and the insulating properties are reduced. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of the plate is stable and has no gaps, which solves the problems of other materials, penetration, frosting, condensation and so on.

The introduction of XPS insulation board is roughly these, the application of XPS insulation board is now very comprehensive, if you want to buy XPS insulation board as a building material, then you must choose a brand worthy of the new, sometimes, believe that the brand benefit is also very helpful to your choice.
