Product TextsCommon features of Crastin? thermoplastic polyester resin include mechanical and physical properties such as stiffness and toughness, heat resistance, friction and wear resistance, excellent surface finishes and good colourability. Crastin? thermoplastic polyester resin has excellent electrical insulation characteristics and high arc-resistant grades are available. Many flame retardant grades have UL 識別(recognition) (class V-0). Crastin? thermoplastic polyester resin typically has high chemical a If recycling is not possible, DuPont recommends, as the preferred option, incineration with energy recovery (24 kJ/g of base polymer) in appropriately equipped installations. For disposal, local regulations have to be observed.16	kg	ISO 1133
