Foamable thermoplastic resin particle composition

Abstract

Abstract PURPOSE:To prepare the titled composition capable of preventing the leak of water, oil, fat, etc., and applicable in wider field, by coating the surface of a foamable thermoplastic resin particle containing specific amount of specific hydrocarbon with specific amount of a phosphoric acid ester containing perfluoroalkyl group. CONSTITUTION:The surface of a foamable thermoplastic resin particle containing 1-10wt%, based on the particle, of a foaming agent comprising volatile hydrocarbon (e.g. propane) having a boiling point lower than the softening point of said resin particle, is coated with 0.01-0.2wt%, based on the resin particle, of a phosphoric acid ester containing perfluoroalkyl group (e.g. the compound of formula) and 0.01-0.05wt%, based on the resin particle, of preferably a binder (e.g. sodium alginate) to obtain the objective foamable thermoplastic resin particle composition. USE:Food vessel, food container, portable handy ice box, etc.
