Product Description

This product is used E-glass fiber as raw material into a short length of 6cm to 9cm long staple, and then by the decomposition of carding, puffing into a very fine form of blankets, acupuncture into the machine, with thousands of branch rolling pin Up and down in a row from gill slit. The main ingredients for the aluminum oxide and silicon soil calcium oxide, whether it is heat-resistant, tensile, strength and toughness, fire resistance, corrosion resistance, electrical insulation and so on, very good, it has a very high insulation, sound-absorbing, dust removal efficiency of more than Filter fabric, and other characteristics.
