Lagging Performance Specifications
Cold Vulcanised Ceramic Lagging
Cold Vulcanised Ceramic Lagging – Natural
Ceramic lagging manufactured using high abrasion resistant ceramic tiles vulcanised to an abrasion resistant top rubber layer and a buffed CN bonding layer to provide high levels of adhesion. Can be supplied in long rolls or in strips with rubber ends to fit pulley face width length.
