The difference between the thermal insulation effect of extruded plastic board and polystyrene parti

Differences: 1. Excellent thermal insulation.

It has the characteristics of high thermal resistance, low linearity and low expansion ratio, and the closed cell rate of its structure has reached 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 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 plate, 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, widely used in geothermal engineering, highways, airport runways, square ground, large cold storage and car interior decoration insulation and other fields.

3. High-quality water-repellent and moisture-proof.

Water absorption 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. Light texture and easy to use.

The completely closed-cell foaming chemical structure of the XPS board and its honeycomb physical structure make it lightweight, high-strength, easy to cut, transport, not easy to break, and easy to install.

5. Good stability and anti-corrosion.

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

6. Environmental performance of the product.

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

Extruded plastic board is better.

The integrity of the extruded plastic board is good, the thermal insulation effect is uniform, and it is difficult to ensure the consistency of the thickness in the construction of polystyrene particles; The area of the extruded plastic board is large, the construction speed is fast, and the polystyrene particles need to be stirred, which is a wet operation and the construction speed is slow; Can the mixing process of polystyrene pellets ensure that the material is fed in proportion? And it is more troublesome to wipe it, and it is not easy to construct.

Each has its own advantages and disadvantages, and the scope of use is different. Extruded plastic board is suitable for roof insulation (high compressive strength), external wall insulation (thin thickness, does not occupy indoor area), and benzene board is suitable for external wall insulation (flexible and breathable).

Thermosetting insulation board TPS real gold board and XPS extruded polystyrene board are common insulation materials, and there are some differences in their thermal insulation effect, service life, scope of application, etc.

Comparison of materials. TPS real gold plate is a thermosetting material with good high temperature resistance, which can withstand thermal expansion and contraction at high temperatures.

XPS extruded polystyrene board is an extruded product with polystyrene as the main raw material, and its high temperature resistance is relatively weak.

Comparison of service life.

The service life of TPS real gold plate is relatively long, up to more than 30 years, and the compressive performance and tensile strength of TPS real gold plate are also high, which can withstand large loads.

XPS extruded polystyrene board is relatively brittle and susceptible to deformation or cracking due to external forces. The service life of XPS extruded polystyrene board is generally about 20 years.

Scope of application. TPS real gold board is suitable for thermal insulation and insulation in high-temperature environments, such as thermal power plants, petrochemical plants and other industrial fields;

XPS extruded polystyrene board is suitable for thermal insulation in the construction field, such as roof, wall, ground and other parts.

To sum up, there are some differences between TPS real gold board and XPS extruded polystyrene board in terms of thermal insulation effect, service life, scope of application, etc., and the specific choice should be comprehensively considered according to actual needs.

Extruded polystyrene board is an insulating board.

Extruded polystyrene board is a common insulation material, which has good thermal insulation and waterproof properties, and is widely used in construction projects. Let's take a closer look at the features and benefits of extruded polystyrene board. Extruded polystyrene board has excellent thermal insulation properties.

Its thermal conductivity is very low, generally between, much lower than traditional insulation materials such as glass wool, rock wool, etc. This means that extruded polystyrene panels can better maintain indoor temperatures, reduce energy consumption, and reduce energy costs.

The waterproofing performance of extruded polystyrene board is also very good. Due to the special production process, the surface of the plate is not flat in the early air, without any pores and gaps, which can effectively prevent moisture penetration. This is very important for waterproofing buildings to avoid losses due to water seepage.

The benefits of using extruded polystyrene board as an insulation board

Extruded polystyrene board has good thermal insulation effect. It has a very low return coefficient of thermal conductivity and excellent thermal insulation performance. The use of extruded polystyrene board as insulation board can effectively prevent indoor heat loss and keep the indoor temperature stable, so as to achieve the purpose of energy conservation and emission reduction.

Extruded polystyrene board has a long service life. It is extremely durable and will not suffer from age, corrosion, etc. over time. The use of extruded polystyrene board as insulation board can ensure the long-term service life of the building and reduce the cost of maintenance and replacement.

Extruded polystyrene board is easy to build. It has the characteristics of light weight, good flexibility, can be easily cut, spliced, and suitable for buildings of various shapes. The use of extruded polystyrene board as insulation board can be completed quickly and conveniently, reducing the waste of manpower, time and cost.

Composite polystyrene insulation board and extruded plastic board are both building exterior insulation materials, in contrast, there are several differences between them:

1.The raw materials are different: the composite polystyrene insulation board is made of expanded polystyrene (EPS) as the core material, and then coated with polyina styrene phenol board on both sides, and finally compounded and pressurized; Extruded plastic board is extruded by extruder polystyrene foam material and processed into board.

2.The density and compressive strength are different: the density of extruded plastic board is higher and the compressive strength is greater, generally 150-600kpa; The density of composite polystyrene insulation board is lighter and the compressive strength is smaller, generally 80-150kpa.

3.The moisture-proof performance is different: the extruded plastic board has better moisture-proof performance, while the composite polystyrene insulation board is relatively poor.

4.The construction methods are different: the extruded plastic board can be constructed without holes or seams, while the composite polystyrene insulation board needs to be cut and then glued together at the joints.

5.Different costs: Due to different manufacturing processes and materials, extruded plastic boards are higher than composite polystyrene insulation boards.

Depending on the specific application scenario and the desired performance, different insulation materials can be selected.

<>First of all, the weather resistance of the two is different. The weather resistance of extruded plastic board is generally more stable than that of polystyrene board. In the case of temperature differences, the function of the extruded board will not decrease.
