Extruded Polystyrene Foam Board Introduction

Posted on January 9 2013 by XPS board is widely used in moisture-proof insulation of walls, flat concrete roof and steel roof insulation, and low temperature storage ground parking platforms, airport runways, highways and other areas. in trim boards, waterproof foam board, China PVC mouldings exporter

What is an Extruded Polystyrene Foam Board?



Extruded polystyrene foam board is referred as extruded board, also known as XPS board. It is a special process continuous extrusion the foam molding material, smooth surface of the dura mater, the internal completely closed-cell foam, honeycomb structure has high compressive strength, light weight, wear-resistant, non-absorbent, non-degradable and other characteristics. Compared with EPS polystyrene foam board, XPS trim boards have greater advantage in strength, heat resistance, resistance to water vapor permeability. Even after being immersed in water, XPS board can maintain good insulation properties and compressive strength, especially suitable for the thermal insulation of buildings.

Extruded Polystyrene Foam Board Performance



Insulation: thermal conductivity is lower or equal to 0.028w / m • k (W / m • Kelvin), thermal conductivity is much lower than other insulation materials with high thermal resistance, low linear expansion characteristics, widely used in roof insulation systems, cold storage, and internal and external walls. Absorbent: waterproof foam board, as an insulation material, water absorption is the extremely important technical indicator. If water absorption is too high, it will result in poor insulation properties. The closed-cell structure of XPS board can effectively prevent the penetration of water molecules, and even suffered mechanical damage during construction XPS board is able to maintain low water absorption. Green: XPS board stable chemical properties, non-volatile harmful substances, but also will not break down or mildew. XPS board in the production process uses environmentally friendly materials, and will not emit harmful gases, and the generated solid waste processing also may be recovered.

Use and Advantages of Extruded Polystyrene Foam Boards



XPS board is widely used in moisture-proof insulation of walls, flat concrete roof and steel roof insulation, and low temperature storage ground parking platforms, airport runways, highways and other areas. The as low as possible of thermal conductivity is the goal of all insulation materials, the XPS board thermal conductivity is much lower than the EPS board, the thermal conductivity of polyurethane foam insulation mortar, and perlite insulation materials. The general insulation material is easy to be aging after used for several years, and the insulation performance is getting poor. XPS board has excellent anti-corrosion and anti-aging properties, and the effective service life is up to 30 years to 40 years. XPS board honeycomb structure has a very high strength, unlike polyurethane foam, phenolic foam is easily crisp, unbreakable, and easy to transport and install.
