Product introduction:

Fire door core board produced by our company using expanded perlite as the main raw material, inorganic adhesives and chemical additives mixed with a certain proportion, through a set of process as. As a result of the expanded perlite is a natural perlite ore, structure after high temperature above 1300 DEG swell and become, granular spherical body hollow honeycomb, so fire door core board made is an ideal product for natural green environmental protection.

From raw materials into the factory to the finished product, the entire manufacturing process through the production and inspection strict and meticulous, coupled with our company's special fireproof glue, steel wooden fire door core board production by domestic customers to use and after testing, fire resistance limit to the new national standard of first class fire door.

Fire door core board, fireproof glue produced by our company have passed the combustion properties of GB grade 8624-2006/A1 (NO:200710615), GB/T 20285-2006 "material smoke toxicity risk classification" AQ1 level (NO:200810831) test.
