Class A Vermiculite Heat insulation & Heat resistance irregular block

 

Product Introduction

Class A heat insulation & heat resistance irregular vermiculite board is made of light weight, heat insulation & heat resistance high temperature firing vermiculite. It can help rapid temperature rising and temperature maintaining for furnace. The light weight has easier operation which fits the more and more strict industrial requirement and widely used in various industrial furnace & experimental furnace.

Characteristic

   High heat insulation & heat resistant ability

   Made of inorganic material, non-ignitable, eco-friendly

   Drug tolerance, acid proof & alkali resistance

   Good strength maintain after high temperature heating

   Little shrinkage and stable dimension in repeat heating, for making of expanded vermiculite with high temperature firing

   Lightweight, high operation and installation ability, easy processing, Construction cost reduce

   Heat shock resistance

   Electrical insulation property

   Excellent processing ability & machine ability

Application

   A1~A3 products can be applied directly to hot side of low temperature oven, drying oven etc.

   A1~A3 products can be applied at the back side of refractory material in various high temperature industrial furnaces. Its suitable for combination with high temperature refractory insulation brick

   Widely used as heat insulation board for furnace, kilns, pizza ovens, hot compression furnace, heating induction furnace
