Shanghai GongYe FiberGlass needlemat has been specifically
developed for use in vehicle exhaust silencer applications.
Manufactured from 9 micron filament E-Glass fibers that are
specially carded to produce a high volume batt. This is then
mechanically needled to bond the fibers, which results in a
dimensionally stable mat or felt, possessing excellent thermal and
acoustic insulating properties without any chemical binder.
