Fireproof board:
Because of owning high proportion MGO, MgCl2 and perlite as materials, fireproof board has perfect fire-resistant performance. It can be expanded rapidly through high temperature. We ever had one professional test that 9mm thickness fireproof board can be last 2hours in the fire. Therefore it is widely used as fire door core, wall partition, furniture and public place of entertainment.
