What is the difference between blown molded board and extruded board

The blow molding plate has a hollow inner cavity of molding and comprises an upper wall body that forms an upper surface and a lower wall body that forms a lower surface, the fireproof board is set to a shape that is suitable for the blow molding board, and the lower surface of the fireproof board and the upper surface of the upper wall body of the blown molding plate are combined together by hot melt high-temperature pressing. After adopting this structure, the composite desktop board not only has the advantage of light weight of the blown molding board, but also has the characteristics of high temperature open flame resistance of the fireproof board and the surface is easy to be made into decorative colors and patterns, integrates the advantages of the two kinds of plates, makes the composite desktop board have the advantages of low cost, less material, easy processing, light weight, easy automation of production process, smooth and clean surface.

XPS insulation board is an extruded polystyrene thermal insulation board, referred to as (extruded board), which is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polyinclusions, heated and mixed while injecting catalysts, and then extruded and pressed into molding. Its scientific name is extruded polystyrene foam for thermal insulation (XPS for short), 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 compressive resistance, and aging resistance (almost no aging decomposition phenomenon in normal use).

The main reason is that the molding process is different, the so-called blow molding should be foam molding, and extrusion is extruded, of course, the composition of raw materials is also different, and the physical density is also different.

<> fact, blow molding plate is a kind of material with a molded hollow inner cavity, and includes both the upper wall body that forms the upper surface and the lower wall body that forms the lower surface. This material has a lot of uses, generally common as a fireproof material, the specific manufacturing method is to design the fireproof board to adapt to the shape of the blow molding board, and then the lower surface of the fireproof board and the upper surface of the blow molding board are melted at high temperature by hot melt adhesive, and the two are pressed and fitted tightly in a dry Kai Qi, the use of this structure of the material can be well combined with the advantages of the two in one, not only has the fireproof characteristics of the fireproof board, but also has the light weight, low cost of the blow molding board, easy to process, The basic automation of the production process and the flatness and smoothness of the material surface have advantages. In addition, blow molding board is also used in fine arts, that is, you can create blow molded paper prints, that is, blow molded thickened paper is used as the base material of printmaking, and then you can scratch and engrave on it, and finally paint pastel or ink, etc., rubbing into prints that are very interesting for children.

In fact, there are many uses of blow molding boards, here are two kinds of them listed with you, after reading these calls, I believe that everyone will have a similar understanding of this kind of thing.

Extruded board is a rigid sheet made of polystyrene resin as the main raw material, which is molded by high-mix extrusion and continuous foaming by special process. It is a material that is continuously extruded and foamed by a special process, the hard film formed on the surface is uniform and flat, and the internal completely closed-cell foaming is continuous and uniform, forming a honeycomb structure, so it has the characteristics of high compressive resistance, light weight, non-water absorption, non-breathable and wear-resistant, and non-degradable.

Extruded plastic board: polystyrene foam is divided into two kinds of intumescent EPS and continuous extruded XPS, compared with EPS board, XPS board is the third generation of rigid foam insulation material, from the process it overcomes the complicated production process of EPS board, and has the superior performance that EPS board can not replace.

It is made of polystyrene resin and other additives through the extrusion process to produce a continuous uniform surface layer and closed-cell honeycomb structure of the plate, these honeycomb structure of the thick plate, there will be no voids at all, this closed-cell structure of the insulation material can have different pressures (150-500kpa) and have the same low thermal conductivity (only and endure excellent thermal insulation and compressive performance, compressive strength up to 220-500kpa).

Extruded plastic boardIt is a common insulation board in construction now, which is not common in daily life, and it is estimated that professionals have not even heard the name of extruded plastic board, so what is extruded plastic board? Is the performance of extruded plastic board good? If you are interested in this, you may wish to follow us to find out.

The full name of extruded plastic board is extruded polystyrene foam board, referred to as extruded board, also known as XPS board. It is a rigid foam plastic sheet with polystyrene resin supplemented by polymer heated and mixed, injected with a catalyst, and then extruded into a continuous closed-cell foam.

Is the performance of extruded plastic board good?

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 the expanded polyurethane, the leading edge is self-evident. Practice has proved that the thermal insulation effect of 20mm thick extruded plastic board is equivalent to 50mm thick expanded polystyrene and 120mm thick cement perlite, so extruded plastic board is the best choice for building insulation at present.

2. Excellent high strength and compressive resistance.

Due to the special structure of the extruded plastic board, its compressive strength is extremely high, the impact resistance is very strong, according to the different types and thickness of the extruded plastic board, 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 and thermal 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, and the structure of the insulation material is destroyed, so that the compressive resistance and thermal insulation performance of the board decreases. Because the molecular structure of polyphenyl nanosanene itself does not absorb water, the molecular structure of the plate is stable and there is no gap, 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 and honeycomb physical structure of extruded plastic board 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, even if the extruded plastic board is used for 30 40 years, it can still maintain excellent performance, and will not decompose or mildew, and there is no volatilization of toxic substances.

6. Environmental performance of the product.
