Title:
FLAME-RETARDANT RESIN COMPOSITION FOR TRANSMISSION SIDE MEMBER IN LASER WELDING
Document Type and Number:
WIPO Patent Application WO/2007/077794
Kind Code:
A1
Abstract:
Disclosed is a flame-retardant resin composition (for a transmission side member)
for laser welding, which is composed of a polyester resin (A) and at least one phosphinic
acid material (B) selected from phosphinates, diphosphinates and polymerized
products of them (preferably a metal salt or the like). The laser light transmittance
of a molded article of such a resin composition may be not less than 15% when the
molded article has a thickness of 2 mm. The resin composition may further contain
a fluorine-containing resin, a nitrogen-containing flame retardant (such
as a triazine compound and cyanuric acid and/or isocyanuric acid and a salt),
and/or a filler (glass fibers or the like). This resin composition enables to
attain both high level of laser welding performance (laser transmission) and
high flame retardance.
