SABIC VALOX™ FR 553 PBT (Asia)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT)
Material Notes:	VALOX 553 is a 30% glass filled flame retardant Polybutylene Terephthalate/Polycarbonate (PBT/PC) injection moldable grade. It has excellent chemical resistance and a UL94V0@0.86mm and 5VA@2.3mm flame rating. This is a good candidate for applications needing reduced shrinkage/warpage including appliance handles, spotlights, electric motors, and pump housings Information provided by SABIC
