ALLURETHANE / Products / Blowing Agent
A blowing agent is a substance which is capable of producing a cellular structure via a foaming process in a variety of materials that undergo hardening or a phase transition, such as polymers, plastics, and metals. It is typically applied when the blown material is in a liquid stage. The cellular structure in a matrix reduces the density, increasing thermal and acoustic insulation, while increasing relative the stiffness of the original polymer.
Allurethane supplies different grades of blowing agents to the polyurethane industry, for instance :
Methylene chloride (MC)
