XPS extruded insulation board is an extruded polystyrene heat insulation board. It is made of polystyrene resin as raw material plus other raw materials and polymers. It is heated and mixed while injecting a catalyst, and then extruded and formed. Manufactured from rigid foam panels.
It has a closed-cell honeycomb structure, with extremely low water absorption, low thermal conductivity, high compression resistance, and aging resistance).
1. Thermal insulation
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. The closed cell rate of its structure has reached more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring its long-lasting and stable thermal insulation performance. Compared with foamed polyurethane, it is 80% The closed cell rate is self-evident. Practice has proved that the 20mm thick XPS extruded insulation board has the same thermal insulation effect as 50mm thick expanded polystyrene and 120mm thick cement perlite. Therefore, this material is the best choice for building insulation.
2. Lightweight and easy to use
The completely closed-cell foaming chemical structure and the honeycomb physical structure of the XPS board make it light and high-strength, easy to cut and transport, not easy to break, and easy to install.
3. Hydrophobic and moisture-proof
Water absorption is an important parameter to measure insulation materials. After the thermal insulation material absorbs water, its thermal insulation performance decreases. Under low temperature conditions, the sucked water is easy to freeze, which destroys the structure of the thermal insulation material, thereby reducing the compression resistance and thermal insulation performance of the board. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable and there are no gaps, which solves the problems of water leakage, penetration, frosting, and condensation of other materials.
