NON ASBESTOS FLEXIBLE MOLDED

Redco Non-Asbestos Flexible Molded - 4311
 
Type of Material:
Redco R-4311 Non Asbestos Flexible Molded
Material Description:
Extrusioned material, dark grey color, flexible to vulcanize, with mineral fibers and rubber binder.
Characteristics:
Before Vulcanizing, it is a flexible material which fits to any diameter of drum, easy handling. After Vulcanizing, it is a rigid material, with medium friction coefficient in normal and hot; the mineral finbers give it good structural resistance and has resin residual no cured of 2.5%
