Trimat MR 8728 Brake Lining

Technical Specification Sheet

Trimat MR 8728 is, a fully cured, flexible, non-asbestos, non-metallic friction material compounded with synthetic rubber.

Applications

Trimat MR 8728 is suitable for industrial applications where a medium co-efficient of friction is required. Due to the flexibility of the materials it is possible to offset any differences on radius.

The material is in a fully cured condition and is suitable for both bonding and rivetting.
