XPS thermal insulation material

HUAMEI brand extrusion and expanded polystyrene (XPS) thermal insulation boards are made with polystyrene. Through special process, the hard expanded board is extruded. There is a sealed and foamed structure, which is an environmental protection material with the performances of high-resist compression, waterproof, moisture-proof, air proof, light weight, anti-corrosion, long service life and low conductivity factor and so on.

HUAMEI brand extrusion and expanded polystyrene (XPS) thermal insulation boards can widely used as thermal insurance and moisture-proof materials for wall, concrete roof, steel-structure roof, lower-temperature storage floor, car platform, air landing strip, high-way and other fields. It can control frost heaving of the ground and really a high-quality and low price material.

During the production process of Huamei extruded polystyrene (XPS) B1-class products, we use the high-quality heat-resistant flame retardants, and make them to mix with the main ingredient evenly and thoroughly by using world’s most advanced mixing conveyor, so as to solve the problem of uneven distribution of flame retardants that exist in other domestic manufacturers. The products B1 are in compliance with state regulations to alleviate the trepidation.



Product Features

Best and Long thermal insulation property

HUAMEI brand extrusion polystyrene (XPS) thermal insulation boards, with the conductivity factor of 0.028 W/m·k, has its good properties such as high thermal resistance and low linear expansion coefficient. Its conductivity factor is much lower than others such as EPS board, expanded polyurethane, thermal insulation plaster and cement perlite. Because of its stable chemical and physical structure, it has Best and Long thermal insulation properties, so it is one of the best thermal insulation materials in the world.


Good Water-proof and Moisture - proof Properties

HUAMEI brand extrusion polystyrene (XPS) thermal insulation boards has intensive obturation structure. There is no any gaps at the surfaces of the board, so it has lowest water absorption, best moisture-proof property.


Environmental Protection

HUAMEI thermal insulation boards (XPS) has stable chemical structure which can not be resolved to release harmful wastes. It utilizes international advanced CO2 foaming technique instead of traditional Freon foaming without Ozone Depletion.The harmful gas and waste water will be not produced in the production.The leftover bits and pieces can be reused。It is an environmental protection material。


Anti - corrosion and Long Service Life

Normal hard expanded thermal insulation materials will be aging after several years’ service, which will reduce their water absorption property. Because of good water-proof and anti-corrosion.


High - resist Compression Property

As the foamed structures are connected tightly, HUAMEI brand extrusion polystyrene (XPS) thermal insulation boards has high-resist compression, even through it is soaked in the water for a long time. It has best impulse strength if it is used for car platform, air landing strip and high-way road.


Light and Hard

As the foamed structures are connected tightly, HUAMEI brand extrusion polystyrene (XPS) thermal insulation boards is light and hard, and is not ease to damage like as expanded polyurethane and phenolics resin. It is ease to transport, install and cut. When it is used for thermal insulation of roof, it still has high compression of the structure.
