METHOD FOR PREPARING THERMOPLASTIC POLYURETHANE POWDER BY NON-AQUEOUS PHASE SUSPENSION POLYMERIZATION, AND POLYURETHANE POWDER PREPARED BY USING METHOD

摘要

Disclosed are a method for preparing thermoplastic polyurethane powder by non-aqueous phase suspension polymerization, and the polyurethane powder prepared by using the method. The spherical polyurethane powder is good in fluidity and fast in melting speed, and physical and chemical properties and particle sizes of the spherical polyurethane powder can be adjusted according to use requirements; the spherical polyurethane powder can be widely applied to powder coating industry, plastic modification industry, powder-based additive manufacturing, and foamable polyurethane elastomers.
