Blowing Agent

Thermally expandable microspheres are new age blowing agents with the thermoplastic cell containing low boiling point liquid hydrocarbon. When heated, these microspheres expand greatly in size; the heat boils hydrocarbon while softens the thermoplastic shell and expands the shell.

As it is a hollow balloon, it creates closed cell structure. By selecting the appropriate grade, you can optimize the expansion starting temperature or degree of expansion.

Applications -

• It can be used in weight reduction and appearance improvement purpose for thermoplastics, inks, and coatings.
• Structural Foam (EVA-EM, PVC, PP, PE, Epoxy, Rubber, Silicon, etc), Wall Paper, Sound Damping Coating, Clay, Shoes, and functional filler. It can be used as a mating agent as well.
• It can be used in extrusion moulding, injection moulding, coating, and various other processes such as Press Moulding, Blow Moulding, etc.

Features:-

• Fine, uniform, closed-cell structure
• Expands even in low viscosity system
• No surface pin holes
• Cell size can be controlled by selecting the appropriate grade

Azodicarbonamide is widely used in the foaming of PVC, PP, LDPE, EVA and other plastic articles lgor example windows and doors, gaskets, padded floor mats, artificial leather, gym/exercise mats or shoe soles.
