摘要:
A flameproof thermoplastic resin composition comprises (A) 100 parts by weight of a thermoplastic resin; (B) about 1 to about 40 parts by weight of a sublimational filler; and (C) about 1 to about 30 parts by weight of a flame retardant. The thermoplastic resin composition can solve the problems of high specific gravity and deterioration of flame retardancy caused by adding a conventional filler.

A cross-linked polyphosphonate and a thermoplastic resin composition including the cross-linked polyphosphonate are disclosed. The composition may have excellent flame retardancy and mechanical strength and superior appearance and heat resistance.
摘要:
A non-halogen flameproof resin composition is disclosed. The resin composition includes a base resin including (A) about 80 to about 99% by weight of an aromatic vinyl resin and (B) about 1 to about 20% by weight of a polyphenylene ether; and (C) about 0.5 to about 30 parts by weight of a cyclic t-butyl phosphonate, based on about 100 parts by weight of the base resin comprising (A) and (B).
摘要:
A non-halogen flameproof polycarbonate resin composition is disclosed. The polycarbonate resin composition includes a base resin including (A) about 50 to about 100% by weight of a polycarbonate resin, (B) about 0 to about 50% by weight of a rubber modified aromatic vinyl resin, and (C) about 0 to about 50% by weight of an alkyl(meth)acrylate resin; and (D) about 0.5 to about 30 parts by weight of a cyclic t-butyl phosphonate compound, based on about 100 parts by weight of the base resin comprising (A), (B) and (C). The polycarbonate resin composition can have stability against fire and can be environmentally friendly since it does not contain a halogen flame retardant.
摘要:
Disclosed is a bishydroxyarylsiloxane compound. The bishydroxyarylsiloxane compound has a novel structure in which a particular moiety is introduced between siloxane blocks. Due to this structure, the physical properties of a copolymer of the bishydroxyarylsiloxane compound and a polymer can be tuned. Further disclosed is a method for preparing the bishydroxyarylsiloxane compound.
摘要:
Disclosed herein is a styrenic resin composition comprising (A) about 15 to about 80 parts by weight of a styrenic resin, (B) about 15 to about 80 parts by weight of a polyphenylene ether resin, and (C) about 0.1 to about 25 parts by weight of a phosphoric compound comprising (c1) about 1 to about 30% by weight of an alkyl phosphinic metal salt and (c2) about 70 to about 99% by weight of an aromatic phosphate ester, per 100 parts by weight of a base resin comprising (A) and (B).
