Molded Polystyrene Foam For Thermal Insulation

1200 (length) * 600 (width) * thickness (3CM-30CM)
12kg-24kg/m³
Polystyrene board is a new type of hard, environmentally friendly and energy-saving foam plastic board made of polystyrene resin supplemented with polymers, which is injected with catalyst while heating and mixing, and then extruded to produce continuous closed-cell foaming. It has an independent closed bubble structure inside and is a thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, aging resistance, and low thermal conductivity. It is a commonly used, high-quality thermal insulation and heat preservation material in the construction industry.

Overall Dimension

1. Polystyrene board has excellent thermal insulation performance. Polystyrene board is mainly made of polystyrene, which is originally an excellent low thermal conductivity raw material. It is extruded to form a tight honeycomb structure, which effectively prevents heat conduction. The thermal conductivity of polystyrene board is 0.028/m.k. Polystyrene board has the characteristics of high thermal resistance and low linear expansion rate. The thermal conductivity of polystyrene board is much lower than other insulation materials. At the same time, polystyrene board is light, cheap and has a stable chemical and physical structure, which can ensure the durability and stability of the thermal insulation performance of this material. Therefore, polystyrene board is one of the best insulation materials in the world. 2. Polystyrene board has high strength and compressive resistance. Polystyrene board has extremely high compressive strength. Even if it is blistered for a long time, it remains unchanged. It has great bearing capacity and good impact resistance. 3. Polystyrene board has excellent water and moisture resistance. Polystyrene board has a tight closed-cell structure. The polystyrene molecular structure itself does not absorb water. There are no gaps on the front and back of the board, so the water absorption rate is extremely low, and the moisture-proof and anti-penetration properties are excellent. 4. Polystyrene board has anti-corrosion and durable properties. Polystyrene board has excellent anti-corrosion, anti-aging, thermal insulation, and a service life of up to 30-40 years. 5. Polystyrene board is light, high hardness, convenient construction and low cost. The completely closed-cell foaming structure of polystyrene board forms a light weight, and the uniform honeycomb structure makes it hard, so it is not easy to break, easy to carry, easy to install, easy to cut, and will not affect the bearing capacity of the structure when used as roof insulation. 6. High-quality environmentally friendly. Polystyrene board is not easy to decompose and mildew, no harmful substances volatilize, and the chemical properties are stable. It is a high-quality environmentally friendly product.
Scope of application of polystyrene board Polystyrene board is widely used in wall insulation, flat concrete roof and steel structure roof insulation, low temperature storage ground, airport runway, highway and other moisture-proof insulation.
