130 kg/m3 Aluminum Coated Fiber Glass Mat for Automotive Exhaust Systems Mufflers
Fiberglass needle mats 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.
The needled effect bonds and secures the individual fibers thus ensuring no fiber loss via the perforated tubes. Fiberglass fibers have a minimal amount of surface dressing that is required to assist in processing, this is usually organic i.e. starch and will disappear at temperatures above 200°C.
