Class A Vermiculite Heat insulation & Heat resistance board

        

Product introduction

Class A heat insulation & resistance board has not only high insulation property, heat resistance property, excellent Sound insulation noise reduction performance, but also has good intensity property, durability, workability, acid resistance ability, corrosion resistance ability. It can be combined use according to different purpose and corresponding temperature.   

Characteristic

   High heat insulation & heat resistant ability

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

   Drug tolerance, acid proof & alkali resistance

   Good strength maintaining after high temperature heating

   The main material is high temperature fired vermiculite. It has little change and good dimension stability even after high temperature firing.

   Large panel, lightweight, high operation and installation ability, easy to process, construction cost reducing

   Thermal shock resistance

   Good electrical insulation property

   Excellent process-ability & machine-ability.

Application

   1A3 products can be directly applied to hot side of low temperature oven, drying oven etc.

   A1~A3 products can be applied at the back side of refractory bricks in various high temperature industrial furnaces. It best fit for combined use with high temperature refractory insulation bricks.

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