ASA Composite Roof----（The terpolymer of Acrylonitrile, Styrene and Acrylate）
Application: villa gardening and pavillions.
Great temperature tolerance---- It can work under -40 - +70 °C
Extrodinary thermal Insulation----Coefficient of heat conductivity is 0.325w/m.k., which is 1/310 of that of clay tile, 1/5 of that of cement tile, and 1/2000 of that of 0.5mm thickness color steel tile.
Good insulation----It is nonconductive and they will be kept intact in case of accidental discharge.
Fast Installation----the effecitive width is 880mm.
Green and Enviroment----No asbestos or radioactive element, it can be recycled and can completely meet the requirement of environment protection.
Perfect self-cleaning performance-----The surface is compact and smooth so it will not absorb dust and is clean and new after being washed by rain. No mark is left on the roofing surface.
Stable Volume-----The expansion coefficient is 4.93×10-5㎜/㎜/℃,besides it also has a two-way stretch performance on geometrical shape, which enable it to accommodate to its extension in case of big temperature change.
Excellent waterproof performance-----materials is high weather resistance resin which is compact and does not absort water. And the width is 45% wider than conventional ones. Therefore few joints and better waterproof performance.
Good sound insulation----test shows good absorting effect under noise of rainstorm and strong wind.
Excellent corrosion resistance----The experiment proves that the roofing has not chemical reaction when it is soaked in salt, alkali and various acids under 60% for 24 hours. It is very suitable for use in places where acid rain often falls and coastal areas.
Strong fire resistance----According to GB8624-2006 standard detection conducted by the state authoritative department of fire prevention, its fireproofing performance is ≥ Class B
Good resistance to impact----The shows the roofing doesn’t crack after 1KG steel ball falls on it from 3 meters height. And the resistance to impact under low temperature is also very outstanding.
Lasting color and life----It is able to maintain its color even under long term exposure to such severe conditions as ultraviolet radiation, dampness, heat and coldness. According to the application result in such areas with intensive sunlight as Arizona and Florida, this product is able to ensure for 10 years of color change of ΔE≤5. And we guarantee 20years of life.
Excellent load-carrying ability-----In cold area, the roofing is not damaged or crack if covered by snow all years when the supporting space is 660mm and 150KG of load applied.
