The full name of extruded polystyrene board is extruded polystyrene foam board, referred to as an extruded board, also known as XPS board, extruded polystyrene board.

Application

Widely used in wall insulation, flat concrete roof, and steel structure roof insulation.

It is used for moisture-proof and thermal insulation in low-temperature storage grounds, parking platforms, airport runways, expressways, and other fields.

The extruded board is made of polystyrene resin supplemented by polymer while heating and mixing, injecting catalyst, and then extruding out a continuous closed-cell foamed rigid foam board, which has an independent closed cell structure inside. It is an environmentally friendly thermal insulation material with high compression resistance, low water absorption, moisture resistance, airtightness, lightweight, corrosion resistance, super-aging resistance (almost no aging after long-term use), and low thermal conductivity.

Extruded panels are widely used in drywall insulation, flat concrete roof and steel structure roof insulation, low-temperature storage ground, low-temperature floor radiant heating under heating pipes, parking platforms, airport runways, highways, etc. Frost heave is a heat insulation and moisture-proof material of good quality, low price, and high quality in the construction industry.

Product Features

Excellent and durable thermal insulation

The lowest possible thermal conductivity is the goal pursued by all insulation materials. The extruded board is mainly made of polystyrene, which is an excellent low thermal conductivity raw material, and then extruded with extrusion, the tight honeycomb structure can prevent heat conduction more effectively, and the heat conduction of energy gathering board The coefficient is 0.028W/m·k, and it has the characteristics of high thermal resistance and low linear expansion rate. The thermal conductivity is much lower than other insulation materials. Such as EPS board, foamed polyurethane, thermal insulation mortar, perlite, etc.

Excellent water resistance and moisture resistance

The extruded board has a tight closed-cell structure, the polystyrene molecular structure itself does not absorb water, and there are no gaps on the front and back sides of the board, so the water absorption rate is extremely low, and the moisture-proof and impermeable properties are excellent.

Anti-corrosion, durable

Ordinary rigid foam insulation materials are prone to aging after several years of use, which will lead to water absorption and performance degradation. The extruded board has excellent anti-corrosion, anti-aging, and heat preservation, and can still maintain its excellent performance under high water vapor pressure, and its service life can reach 30-40 years.
