摘要:
The present invention provides a polyester resin composition for injection-molding which is excellent in mold releasability, and is capable of providing light reflectors which are excellent in apparent luminance and reflectivity, and suppressed in hazing even used under high temperatures. A polyester resin composition for injection-molding comprising, (A) 100 parts by weight of a polyester resin, (B) 0.1 to 20 parts by weight of zirconium silicate having an average primary particle size of 10 μm or smaller and (C) 0 to 5 parts by weight of a chelating agent capable of forming a chelate with mono- to tetra-valent metal ions.
摘要:
Provided is a resin article comprising a non-halogen series flame retardant to which high flame resistance is imparted. A flame-retardant polybutylene terephthalate series resin composition comprising 100 parts by weight of a polybutylene terephthalate series resin (A) having a glass-transition temperature according to the dynamic viscoelastic method of 0° C. to 75° C., and 5 to 70 parts by weight of a metal phosphinate (B).
摘要:
A thermoplastic polyester resin composition comprising 100 parts by weight of a thermoplastic polyester resin (A), 5 to 40 parts by weight of a phosphinate (B), and an organosiloxane (X); wherein the phosphinate is a calcium salt or aluminum salt of phosphine acid having the anion part having a particular structure; which, as the organosiloxane (X), comprises 1.5 to 10 parts by weight of an organosiloxane compound (X-1) or 0.01 to 5 parts by weight of an organosiloxane polymer (X-2), relative to 100 parts by weight of the thermoplastic polyester resin (A); and wherein the organosiloxane compound (X-1) comprises organic groups bonding to a silicon atom directly or through an oxygen atom, and 40 mole % or more of the organic groups are an aryl group, and the organosiloxane polymer (X-2) is in the form of solid at 25° C.
