What is the difference between extruded plastic board and foam board

1. The difference in cost. Typically, extruded polystyrene sheets.

More expensive than foam board. At the same time, there is also a certain gap in the production process of the two, extruded board.

The process is simple, but the strength of extruded polystyrene board is higher than that of foam board, and the thermal insulation performance of extruded board is much better than that of foam board.

2. Differences in characteristics. The strength of the extruded board is higher than that of the foam, and the flame retardant effect of the extruded board is more prominent, and the flame retardant performance of the foam board is relatively poor compared with the extruded board. Therefore, it can be seen as a whole that although both are more commonly used in energy-saving building materials, they are used as floor heating insulation materials.

The performance of extruded plastic board is much better than that of expandable polystyrene foam board.

3. Differences in materials. The most common extruded plastic board is polystyrene.

Resin is used as raw material and continuously extruded into foam through a special process.

Its interior is an independent closed bubble structure, which is a kind of high compressive resistance, non-water absorption, moisture-proof, non-breathable, lightweight, corrosion-resistant, long service life, and thermal conductivity.

Environmentally friendly insulation material with low and excellent performance.

Foam board is made to be volatile.

Liquid blowing agent.

The expandable polystyrene beads, which are heated and formed in the mold after heating and pre-hairing, have the structural characteristics of fine closed cells, and are mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ships, floor heating, decoration and carving, etc.

1. Differences in appearance such as color and density.

1. Polystyrene board is generally white, with very little density, and it can be easily deformed by hand, and it can also be easily broken and broken.

2. Extruded plastic board generally has other colors, red, blue, gray, etc., the density is much larger than that of polystyrene board, and it is not deformed by hand, and it is difficult to break and break.

Second, the difference in structure.

1. The benzene plate belongs to the granular structure, which is composed of one grain and one grain, and there is a gap between the grains, which is easy to disperse into particles.

2. The extruded plastic board belongs to the closed-cell honeycomb structure, with good flexibility, and is torn off from the side into a block structure with small holes.

3. Differences in use.

1. The thermal conductivity of extruded plastic board is lower than that of polystyrene board. It has great advantages over polystyrene board in terms of thickness. Extruded plastic board has higher compressive or compressive strength than polystyrene board. Therefore, extruded plastic board is often used for roof insulation and basement and floor insulation.

2. Polystyrene board is often used in the field of building energy conservation and thermal insulation.

Summary. Because as a thermal insulation material, the performance of the extruded plastic board is far better than that of the foam board, and the extruded plastic board is conducive to maintaining a stable room temperature, using external wall thermal insulation, because the structural layer of the wall heat storage capacity is larger on the inner side of the wall, which is conducive to maintaining a stable room temperature, so the roof insulation material foam board and extruded board are extruded plastic boards.

Hello, I am a co-teacher Xiao Yi who is good at electronic and digital emotional entertainment and has been engaged in the industry for two years now, and I am happy to serve you.

Dear Hello, Glad to serve you Roofing insulation material foam board and extruded board are extruded board good.

Because as a thermal insulation material, the performance of the extruded plastic board is far better than that of the foam board, and the extruded plastic board is conducive to maintaining a stable room temperature.

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.

Roofing insulation foam board is a hail rot seed of emitted polystyrene material, also known as polystyrene board, EPS board is made of volatile leakage liquid foaming agent, polystyrene beads, heated pre-foaming in the mold made of white objects.

First, the use is different.

1. Extruded plastic board: building roof insulation, steel structure roof, building wall insulation, building ground moisture retention, square ground, ground frost heave control, air conditioning ventilation ducts, etc.

2. Foam board: mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ships, floor heating, decoration carving, etc.

Second, the characteristics are different.

1. Extruded plastic board: excellent thermal insulation, excellent high strength and pressure resistance, high-quality water repellency and moisture resistance, light texture, easy to use, stability, good corrosion resistance, and environmental protection performance.

2. Foam board: maintain the layout of the main body of the building and extend the life of the building. Because the external insulation layer is placed on the outside of the layout, it reduces the stress of layout deformation caused by temperature changes, and reduces the corrosion of the layout by harmful substances and ultraviolet rays in the air.

Third, the production of raw materials is different.

1. Extruded plastic board: a rigid foam board made of polystyrene resin as raw material plus other raw materials and polymers, heated and mixed while injecting a catalyst, and then extruded and pressed. 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).

2. Foam board: EPS board is a white object made of expandable polystyrene beads containing volatile liquid foaming agent, which is heated and pre-formed in a mold.

Dear, hello, I am glad to answer for you: extruded plastic board and foam board thermal insulation ** a good answer: dear, hello, and foam board is the use of polystyrene beads, after heating to form a white object, is used on the building wall, thermal insulation function is better.

Extruded thermal insulation board is better, it is a rigid foam plastic board with polystyrene resin supplemented by polymer in heating and mixing at the same time, injected with catalyst, and then extruded continuous closed-cell slow-buried foaming rigid foam board, which is an independent closed bubble structure, which is an environmentally friendly thermal insulation material with excellent properties such as high compressive resistance, low water absorption, moisture-proof, impermeable, light weight, corrosion resistance, super anti-aging (almost no aging for long-term use), and low thermal conductivity.
