Product Description

Main body beads 
 
Ceramic Beads
 
 Ceramic  Beads for heating elements
 
Application:  As ceramic parts of flexible pad and channel heaters at operations of pre and post weld heat treatment; Welding process, stress-relieving, pre-heating & post heating, ship-building, other resistance-heating environments.
 
Properties: Higher density, higher surface finish and uniformity than heat press cast method, excellent thermal conductivity and heat transfer, resistance against thermal shock and mechanical abuse.
