XPS Board/Extruded Polystyrene Insulation Board/Building Wall Material

Specifications

Product introduction

XPS (extruded polystyrene) insulation board is comprised of import polyethylene and manufactured through a special plastic extruction process with high density. It is produced by environmental material, and generates no harmful gas, the leftover material can be reuse, will not be decompose and mildew, anticorrosion. It has smooth surface through extrusion, and has completely closed cell inside. This kind of material has excellent heat insulate performance, high moisture resistance, lightweight excellent compressive strengths, and anticorrosion. This is ideally use for the construction industry.

XPS insulation board has 99% closed cell rate. As a result for high heat resistance, low expand rate and low thermo conductivity. The heat insulation effect of 25mm thick XPS board is superior than 120mm thick concrete perlite. It is usually used in apartments, high-rise buildings, workshop, cold storage warehoused for heat insulation. Compare XPS with ESP, ESP is bigger in cells and loser in structure.
