Thermoexpandable Microspheres
Thermoexpandable Microspheres refers to the thermal expansion foaming macro particle formed by packaging low boiling point hydrocarbon inside the enclosure of thermoplastic polymer. It is white solid powder particle under normal temperature. Independent hollow bubbles can be formed through the integral sudden expansion of expanding low boiling point hydrocarbon and the softened thermoplastic enclosure by adding heat swelling agent. It thus plays a special role in producing injection molding foaming shoe soles such as PVC and TPR type ones.
Product Introduction
Thermoexpandable microspheres (TEMs) are microscopic spheres with a thermoplastic shell enclosing a volatile liquid or gas core. They expand significantly when heated, due to the vaporization of the core material, creating a cellular structure within materials like paints, construction materials, and printing inks. Microsphere expansion agent provide benefits such as lightweighting, thermal insulation, texture enhancement, and impact absorption, making them valuable in industries requiring advanced material properties.
