synonymPlastic extruded board(Extruded board) generally refers to extruded polystyrene board
The full name of extruded polystyrene board isExtruded polystyrene foam board, referred to as extruded board, also known as XPS board, extruded polystyrene board.
1. Widely used for wall insulation, plane concrete roof and steel roof insulation;
2. It is used for moisture-proof and thermal insulation of low-temperature storage ground, parking platform, airport runway, expressway and other fields.
Extruded board is based onPolystyrene resinAssisted by polymer, while heating and mixing, the catalyst is injected, and then the continuous closed cell foam is extrudedRigid foam plasticThe interior of the board is an independent closed bubble structure, which is environmentally friendly and has excellent performance such as high compression resistance, low water absorption, moisture resistance, air tightness, light weight, corrosion resistance, super aging resistance (almost no aging after long-term use), low thermal conductivity, etcThermal insulation material。
Extruded board is widely used in dry wall insulation, flat concrete roof and steel roof insulation, low temperature storage ground, low temperatureradiant floor heating Damp proof and heat insulation under heating pipes, parking platforms, airport runways, expressways and other fields to control ground frost heave are high-quality and inexpensive heat insulation and moisture-proof materials in the construction industry.

1、 Excellent and lasting thermal insulation
As low as possiblethermal conductivityIs allThermal insulation materialThe goal pursued.The extruded board is mainly made of polystyrene, which is an excellent raw material with low thermal conductivity. With the help of extrusion extrusion, the compact honeycomb structure can more effectively prevent heat conduction. The thermal conductivity of the energy gathering board is 0.028W/m · k, which has the characteristics of high thermal resistance and low linear expansion rate.The thermal conductivity is far lower than other insulation materials.Such as EPS board, foaming polyurethane, thermal insulation mortar, perlite, etc.
2、 Superior water resistance and moisture resistance
Extruded boards have a close closed cell structure,polystyreneThe molecular structure itself does not absorb water, and there is no gap between the front and back of the board, so the water absorption rate is extremely low, and the moisture-proof and impermeable properties are excellent.
General hard foamingThermal insulation materialIt is easy to age after several years of use, which will lead to water absorption and performance degradation.The extruded board has excellent corrosion resistance, aging resistance, thermal insulation, and can still maintain its excellent performance under high steam pressure, with a service life of 30-40 years.
Type:
According to the compression strength p and skin of the product, it can be divided into the following ten categories:
a. X150-p greater than 150 kPa, with skin;
b. X200-p greater than 200 kPa, with skin;
c. X250-p greater than 250 kPa, with skin;
d. X300-p greater than 300 kPa, with skin;
e. X350-p greater than 350 kPa, with skin;
f. X400-p is more than 400 kPa, with skin;
g. X450-p is more than 450 kPa, with skin;
h. X500-p is greater than 500 kPa, with skin;
0. W200-p is greater than 200 kPa, without skin;
j. W300 -- p is greater than 300 kPa, without skin.
Products with other surface structures shall be negotiated by both parties
According to the edge structure of products, it can be divided into the following four types:
1. SS flat head products
2. Si type products (lapping)
3. TG type product (birch groove)
4. RC type product (gutter)
