Product Text
Common features of Crastin® thermoplastic polyester resininclude mechanical and physical properties such as stiffness andtoughness, heat resistance, friction and wear resistance, excellentsurface finishes and good colourability. Crastin® thermoplasticpolyester resin has excellent electrical insulation characteristicsand high arc-resistant grades are available. Many flame retardantgrades have UL recognition (class V-0). Crastin® thermoplasticpolyester resin typically has high chemical and heat ageingresistance.
The good melt stability of Crastin® thermoplastic polyesterresin normally enables the recycling of properly handled productionwaste. If recycling is not possible, DuPont recommends, as thepreferred option, incineration with energy recovery (24 kJ/g ofbase polymer) in appropriately equipped installations. Fordisposal, local regulations have to be observed.
Crastin® thermoplastic polyester resin typically is used indemanding applications in the electronics, electrical, automotive,mechanical engineering, chemical, domestic appliances and sportinggoods industry.
Crastin® 6129 is an unreinforced, high viscosity polybutyleneterephthalate for extrusion and injection moulding.
