Technical Datasheet | Supplied by Celanese
VANDAR® 4662Z MD-BK204 BLACK is a black colored, dimensionally stable, tough polybutylene terephthalate alloy) [PBT] with good weatherability, high modulus & moldability and reinforced with 30% glass. Exhibits high ductility, low moisture absorption, good stiffness and high abrasion resistance as well as excellent chemical- & thermal- resistance. Has high impact resistance & notched impact strength at low temperatures while retaining strength and stiffness. Possesses good processability & paintability as well as resistance to organic solvents, fuels, lubricants and brake fluids. Prevents creeping & sagging at much higher temperatures. Is suitable for processing by injection molding and film extrusion. Complies with RoHS, PFOS and PFOA.
