Lagging Performance Specifications
Hot Vulcanised Ceramic Lagging
Hot Vulcanised Ceramic Lagging – FRAS
Hot vulcanising ceramic lagging is manufactured using high abrasion resistant ceramic tiles vulcanised to an abrasion resistant top rubber layer, a buffed CN bonding layer to provide high levels of adhesion and an uncured bonding layer to provide high levels of adhesion after autoclave curing.This ceramic 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.
