Expandable Microspheres for Lightweight Microcellular Applications
Heat-expandable microspheres for creating lightweight microcellular structures
Foamed MicrospheresIndustrial BondingElectronics ProtectionFoam Dressing
Our expandable microspheres consist of a thermoplastic shell encapsulating a hydrocarbon blowing agent. When heated, the shell softens and the internal pressure causes the microsphere to expand dramatically — increasing volume by 40-60 times.
This unique property makes them ideal for creating lightweight microcellular structures in injection molding, extrusion, and compression molding processes. Used widely in automotive, footwear, seal strips, thermal insulation coatings, and industrial applications.
