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.
