Product Description:
Fiberglass needled felt (mat) is mainly used for thermal insulation and acoustic insulation application, and it's also a kind of filter material which is used as medium to purify gas and split solid from liquid. It filters dusts and solid impurities through its pores. Needled mat is featured with good ventilation property, good efficiency with getting rid of dusts, gaseous emission with good cleanliness degree, neat and smooth surface, being not easy to block the pores, being not easy to become deformed, being easy to clean off dusts, long useful time, stable chemical property. Fiberglass needled mat is applied to purify atomosphere and clean off dusts, as filter material in those fields such as metallurgy, chemical engineering, building materials, smelt metal, mechanics, mining, petroleum, medicine, food and so on.
