XPS EPS Extruded Polystyrene Foam External Wall Insulation Board
XPS extruded thermal insulation board external wall roof heat insulation sound insulation board
The extruded polyphenylene insulation board (xps) is a rigid sheet which is continuously extruded and foamed by a special process using polystyrene resin as a raw material. The inside is an independent closed bubble structure, which is a kind of high pressure resistance. , non-absorbent, moisture-proof, airtight, lightweight, corrosion-resistant, long service life, low thermal conductivity and other environmentally friendly insulation materials.

XPS wall and floor heat insulation board advantage
1. Excellent thermal insulation performance: very low thermal conductivity ,used as the insulation structure of the fence structure ,it can be the most economical (with the minimum thickness) materials which can meet the building insulation requirements
2. Carbon dioxide foaming process: The cutting-edge CO2 foaming process replaces the traditional Freon (CFC and HCFC) gas, protects the ozone layer, it is more environmentally friendly and energy-saving, non-radioactive or volatile, formaldehyde-free and safe for both indoor and outdoor use.
3. High compressive strength: Extruded board can provide perfect compression capacity and impact resistance, compressive strength is up to 800KPa. It is more than just a light weight insulating material, its intrinsic mechanical strength enables it to withstand higher load pressure on the ground and underground side walls,provide the solution of thermal insulation and structure as one
4 fire resistance rating: high-end flame retardant formulations combined with the CO 2 foaming process, to produce high-quality flame retardant B1 extruded board, increase fire safety performance of the extruded board
5. Very low water absorption: (≤ 0.29%) has excellent hydrophobic, moisture and impermeability of the performance, and in can ensure that the thermal conductivity will not be reduced due to water absorption, thermal insulation performance can be maintained above 90%, superior Freeze-thaw resistance, and there will be no qualitative changes after long-term immersion or withstand repeated freeze-thaw cycles
