Product Description
Fiberglass needled felt is an advanced material for air cleaning and thermal insulation made by cutting continuous glass fibers into given length and then felting them through a process of filamentizing, napping and needling. Characterized by high temperature resistance, good thermal insulation, superior acoustic absorptivity and high efficiency of cleaning tail gas. It has found wide application in mechanical, electrical, chemical, metallurgical, petroleum, coal, building and traffic industries, suitable for the use as sandwiched heat and sound insulation system in automobile, ship, and train carriages. When treated with a ternary rare-earth cleaning catalyst, it is an ideal material for tail gas cleaning and sound deadening for cars and motorcycles.
