Abstract

The invention provides a foaming styrene resin particles. According to the invention, adhesion does not occur in the pre-foaming process, the fluidity of the foaming particles is good, the peeling of the coated medicaments is inhibited, the agglomerating is good, and oil does not seep. The foaming styrene resin particles provided by the present invention is prepared from styrene resin particles impregnated with a foaming agent. The surfaces of the resin particles are coated with a composition comprising: polyethylene glycol A with a molecular weight less than 400; 0.003 to 0.04 parts by weight of aliphatic acid amide or aliphatic acid diamide, relative to 100 parts by weight of the resin particles; 0.2 to 0.8 parts by weight of aliphatic acid metal salt, relative to 100 parts by weight ofthe resin particles; and polyethylene glycol B with a molecular weight less than 400. Relative to 100 parts by weight of the resin particles, the composition comprises 0.02 to 0.08 parts by weight ofthe polyethylene glycol A and the polyethylene glycol B. The resin particles are coated two times respectively.
