Therm Expandable Microsphere
Trade Name: Therm Expandable Microsphere

Composition

This product is a kind ofcore-shell structure.The wall material is a copolymer of acrylonitrile and its derivatives; The core material is liquid low boiling point organic hydrocarbon.

Properties

When the microsphere is heated to reach a certain temperture, the shell will soften with plasticity. At the same time, the low boiling core material within the microspheres will be heated and vaporized to generatepressure, to realize the foaming purpose. With properties such as stable performance, non-staining, notaffecting the curing and molding speed,this productis suitable for normal or pressurized foaming with foamevenly and ideal fine pore structure.
