RU-7/RW -7 A flexible moulded, non-metallic friction material on a synthetic resin / rubber base, light grey in colour, having medium co-efficient of friction with excellent temperature, wear and fade resistance. Inhibitor of squeal and judder, the lining is suitable for bonding on either surface. It is particularly useful where small stocks must cater for wider range of lining sizes.
The RU- 7 quality is also offered with wire backing where riveting is preferred over bonding and is designated as RW- 7. It has all the friction characteristics of RU- 7 and the wire backing enhances the physical strength of the roll lining.
