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.
Noise Isolation Coefficient
Fiberglass needle mats are suitable for continuous use at temperatures up to 1050°C. Characteristics are a low coefficient of thermal conduction, low heat storage and absolute incombustibility. Fiberglass needle mat is friendly to the skin, not hazardous to health and has excellent resistance to chemicals.
