Product advantages

Product advantages:

Excellent fire performance

It will not burn in case of fire, carbonize at high temperature, melt, shrink or fall

Very low thermal conductivity

There is no burning sensation on the back of the plate when the flame is sprayed at 150 ℃

High strength

Actual picture of treading on 60kg / M ~ 3 board (the weight of treading personnel is 92kg)

Composite fireproof aluminum foil

Effective improvement of fire resistance and strengr


Material Science	weight（Kg/m³）	thermal conductivity W/（m·℃）	Thermal resistance value (0.025㎡×℃/W)	Combustion grade
Phenolic	40~80	0.025	1	Flame retardant B1
polyurethane	20~40	0.025	1	Flame retardant B2
Eps	20~40	0.03	0.86	Flame retardant B2
Xps	20~40	0.041	0.61	Flame retardant B2
Rock wool	80~120	0.053	0.48	Non combustible A
Glass wool	80~120	0.036	0.69	Non combustible A
Foam glass	80~120	0.066	0.066	Non combustible A

Comparison conclusion: phenolic foam insulation sandwich layer has better thermal insulation effect than rock wool, EPS, XPS and other insulation materials, and is equal to polyurethane material; However, the fire resistance of phenolic foam is obviously better than that of polyurethane, and the price is also more favorable than that of polyurethane. Therefore, in terms of comprehensive performance, phenolic foam wins.
