InterSource E-Glass 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.

The mechanical bonding system secures the individual fibers thus eliminating fiber loss via the perforated tubes. InterSource needlemat can be supplied pre-rolled as packs on cardboard mandrels, InterSource packs are wrapped in Polythene sleeves for ease of handling and to reduce any irritation from the glass fiber. We also offer a complete cutting and die-cutting service for more complex shapes.

PROPERTIES OF E-GLASS NEEDLEMAT
E-Glass fibers have a minimal amount of surface dressing that is required to assist in processing, this is usually organic i.e. starch or silage and will disappear at temperatures above 200°C. E-Glass Needlemats are suitable for continuous use at temperatures up to 550°C higher in exhaust applications, however tensile strength continues to reduce noticeably as temperatures increase above 400°C.
