--Excellent thermal insulation property, which makes it hard to moisture condensate, in this ----kind of condition, it is hard for bacteria to embrace, and give us a comfortable air

--Low noise during air circulation

--Low thermal insulation increases the heat loss

--Lightweightness makes more efficient gasoline consumption


--thermal insulation less than 0.04 w/m.k

--water absorption reaches to 0.3% ( 60Kpa, 24H), impermeable

--Soft foam is shocking absorption

--5mm foam:  Air sound insulation 12dB, the impact sound insulation reaches to 19dB

--Temperature resistance: under 120℃, 24h, the ratio of shrinkage of XPE in less than 10%, IXPE is less than 7%.

--Eco-friendly: Crosslinked polyethylene foam meets with the tendency of automotive light-weights, and is non-VOC material
