Product Description

1. General

  HGS Vermiculite Board is the main raw material of expanded vermiculite, mixed with a certain proportion of inorganic adhesive, and processed through a series of processes, it is a kind of plate with high temperature resistance, fire prevention, environmental protection, heat insulation, sound insulation and no harmful substances. After high temperature heating to 1200ºC, it does not produce harmful gases to human health, and the combustion performance reaches grade A.
