Evonik VESTODUR® X7212 black E70149 Polybutylene Terephthalate (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), 40% Glass Fiber Filled
Material Notes:	Self-extinguishing, reinforced polybutylene terephthalate compound with non-migrating and non-corrosive flame retardant. VESTODUR® X7212 black E70149 is a glass fiber-reinforced (45%), semi-crystalline thermoplastic compound for injection molding, based on polybutylene terephthalate (PBT). VESTODUR® X7212 is used for parts of high mechanical and thermal resistance. Test bars made of the compound are rated V-0 self-extinguishing according to UL94 by Underwriters Laboratories Inc. The incorporated flame retardant is non-migrating. The additive has no corrosive effects on metal inserts or neighboring metal parts. Therefore, the compound is distinguished for moldings in the electrical and electronical industry. Laser marking with high contrasts is possible. VESTODUR® X7212 is supplied as cylindrical pellets in polyethylene packaging. Pigmentation may affect values. Property data for dry samples. Information provided by Evonik.
