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
