Polyethylene is a polystyrene foam board which uses a polymer resin supplementing heat while mixing catalyst injection, extrusion and then extruded rigid foam board continuity closed-cell foam. There is a separate closed bubble structure, which is a high compressive strength, low water absorption, moisture-proof, airtight, lightweight, corrosion resistance, super anti-aging (long-term use without aging), low thermal conductivity, excellent performance of environmentally friendly insulation material.
Extrusion plate widely used in dry wall insulation, flat concrete roof and steel roof insulation, low temperature storage ground, low temperature floor heating pipe heating auxiliary radio, parking platforms, airport runways, highways and other areas of moisture-proof insulation, and control ground frost. The material is inexpensive, superb insulation and moisture-proof material in construction.
First, excellent, long-lasting insulation properties.
As lower thermal coefficient of all the insulation material goal, extruded polystyrene board is mainly made by EPS foam. Also, polystyrene was originally an excellent low thermal conductivity material, supplemented by extrusion, and compact honeycomb structure is more effective in preventing heat conduction, which has the characteristics of high thermal resistance, low linear expansion. Thermal conductivity is much lower than other insulation materials, such as EPS board, foam polyurethane, insulation mortar and perlite.
Second, the superior resistance to water, moisture resistance.
Extruded sheet with a tight closed-cell polystyrene molecular structure does not absorb water, and positive and negative plates are no gaps. Therefore, the water absorption rate is very low and moisture and anti-permeability is excellent.
Third, anti—corrosion, durability.
General rigid foam insulation material is easy to aging after years of use, and lead to performance degradation caused by water. The extruded sheet because of excellent corrosion, aging resistance, thermal insulation, water vapor under high pressure, can maintain its excellent performance. Finally, the service life will be up to 30-40 years.
