Trimat GBC Brake Lining

Technical Specification Sheet

Trimat Trimat GBC is a semi-flexible asbestos-free brake lining, manufactured from a solid woven fabric of both natural and man-made yarns , with a brass wire inclusion which helps to stabilise the frictiom value by conducting from the operating surface.

When the woven fabric is impregnated with the specially developed synthetic resin it produces a high friction material with excellent stability and high resistance to wear.

Both surfaces can be supplied ground, making it suitable for bonding and riveting to either internal or external contracting braking systems.

Applications

This material can be supplied for use on oil immersed applications, although the friction value will be much lower than shown on the friction/temperature graph which is based on dry conditions.

A most efficient general purpose brake lining suitable for use on most applications, including winches, cranes, earth-moving and agricultural equipment, forging machinary and many others. Because of its versatility it is of course an ideal quality to stock.
