The phosphorus compound to be used is preferably a trivalent phosphorous compound.
摘要:
To provide a polybutylene terephthalate resin composition that excels in the anti-heat shock property, flame retardation and hydrolysis resistance. A polybutylene terephthalate resin composition is prepared by combining a halogenated benzylacrylate compound, an antimony oxide compound and a carbodiimide compound with the polybutylene terephthalate resin. The content of the carbodiimide compound may be an amount that makes the amount of the carbodiimide functional group to be at least 0.3 equivalents and no more than 5.0 equivalents, when the terminal carboxyl equivalent of the polybutylene terephthalate is set as 1.

摘要:
A laser weldable PBT-series resin composition and a molded product thereof are provided, in which the composition is weldable uniformly and has high welding strength even when the composition comprises a polybutylene terephthalate (PBT) as a base. The laser weldable resin composition comprises 1 to 50 parts by weight of (B) an elastomer (such as a polystyrene-series thermoplastic elastomer or a polyester-series thermoplastic elastomer), 5 to 100 parts by weight of (C) a polycarbonate-series resin, 1 to 10 parts by weight of (D) a plasticizer (e.g., an aromatic polycarboxylic acid ester, and an acrylic plasticizer), and 0 to 100 parts by weight of (E) a filler or reinforcing agent (such as a glass fiber), relative to 100 parts by weight of (A) a polybutylene terephthalate-series resin (a homopolyester or a copolyester). The molded product prepared from the resin composition has a small light transmittance fluctuation range depending on sites to be irradiated of the molded product. Thus, the molded product can be bonded to a counter part article uniformly by a laser welding.
摘要:
A laser weldable PBT-series resin composition comprises a polybutylene terephthalate (PBT)-series resin (A), and at least one resin (B) selected from the group consisting of a polycarbonate-series resin (b1), a styrenic resin (b2), a polyethylene terephthalate-series resin (b3) and an acrylic resin (b4). The PBT-series resin (A) may be a PBT homopolyester, or a PBT-series copolymer modified with not more than 30 mol % of a copolymerizable monomer (e.g., a bisphenol compound or an adduct thereof with an alkylene oxide, and an asymmetrical aromatic dicarboxylic acid). The ratio (weight ratio) of the resin (B) relative to the PBT-series resin (A) [the former/the latter] is about 0.1/1 to 1.5/1. The resin composition may comprise a glass fiber. The resin composition is excellent in laser weldability, and can improve in welding strength of a shaped article formed from the resin composition.
