Lagging Performance Specifications
Cold Vulcanised Ceramic Lagging
Cold Vulcanised Ceramic Lagging – FRAS
Ceramic lagging manufactured using high abrasion resistant ceramic tiles vulcanised to an abrasion resistant FRAS rubber and a buffed Fras CN bonding layer to provide high levels of adhesion. This lagging is for use in applications where there is a risk of fire and/or explosion such as underground coal mines, and grain and sugar handling facilities and is a safety critical item. Can be supplied in long rolls or in strips with rubber ends to fit pulley face width length.
