Chemicla Blowing Agent

Descriptions Chemical blowing agent is a chemical additive that is able to evolve gas through thermal decomposition and produce foam structures in a polymeric matrix. It is largely classified into two: one is organic chemical blowing agent and the other is inorganic chemical blowing agent. Commercial chemical blowing agents produced by Kum Yang are outlined as follows. Azodicarbonamide (CellcomAC Series) p,p'Oxybis(benzene sulfonylhydrazide) (CellcomOBSH Series) pToluenesulfonyl hydrazide (CellcomH Series) pToluenesulfonyl acetone hydrazone (CellcomKE) N, N'Dinitrosopentamethylenetetramine (CellcomA80s) pToluenesulfonyl semicarbazide (CellcomTSS) 5Phenyltetrazole (Cellcom5PT) Sodium Bicarbonate (Kycerol Series) The special features of main chemical blowing agent besides AC are as follows.

You must select the most suitable blowing agent according to their species, specialty, application, processing methods and conditions in cases of plastics and rubbers. Please refer our general selection guide of Cellcom Blowing Agent below attached. Best Selection for Suitable Blowing Agent Please check the properties of ideal chemical blowing agent to make proper sponge. The blowing gas must be evolved within a defined temperature and time. Regular particle size and excellent dispersion in the plastic. The blowing agent should be controlled the decomposition temperature and generated low heat. The gas foamed should not have corrosive action. The decomposition residue should be non-toxic and non-pollution The decomposition residue should not effect to the foam in its chemical and physical properties Non-effective in Polymeric crosslinking and vulcanization. The blowing agent should have a high gas yield and be economic. The blowing agent should have good transportation and storage stability. And select the general blowing agent according to the resin and processing methods. Please refer the selection guide as follows.
