Lagging Performance Specifications

Hot Vulcanised Ceramic Lagging

Hot Vulcanised Ceramic Lagging – Natural

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. Can be supplied in long rolls with the option to make your own strips using end pieces orin strips with rubber ends to fit pulley face width length.

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.
