Class A Vermiculite Heat insulation & Heat resistance irregular block

   

Product Introduction

Class A vermiculite heat resistance & insulation brick belongs to light weight inorganic mineral material, has excellent heat resistance & insulation property. It can reduce the heat loss through furnace wall, accelerate the furnace heating speed, decrease the heating time and save the fuel cost.

Characteristic

   High heat insulation property

   High heat resistance property

   Light weight, easy to process & operation

   Drug tolerance, anti-corrosion

   Thermal shock resistance

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

   Excellent processing ability

Application

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

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

   Backup insulation material for industrial stoves

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

Dimension

*Standard Size: L230*W114*T45mm; Density 400~1200 kg/m3

Except standard size, we can offer OEM for customer requirement, but it will produce model charge, pls kindly understand.
