Blowing Agent
Key Additive in Sponge
Introduction of
Blowing Agent
Chemical blowing agent is a chemical additive that is able to evolve gas through thermal decomposition and produce foam structures in a polymeric matrix such as plastic and rubber and is classified into organic chemical blowing agent and inorganic chemical blowing agent. Commercial chemical blowing agents produced by Kumyang are outlined as follows.
Application
Foams of PVC (Polyvinyl chloride) incorporated with blowing agent are insulation tube, synthetic leather, sandal, wall coverings, floor coverings and so on.
Blowing Agent for PVC
Following blowing agent can be useful for PVC application.
