DuPont™ Crastin® PBT thermoplastic polyester resins are based on polybutylene terephthalate. By making physical and technical modifications, a wide range of products are available that are suited to an enormous variety of industrial applications. In fact, this growing family is currently available in over 100 different grades, approximately half of which are flame retardant.
Grades of Crastin® polybutylene terephthalate
Crastin® Super Fast resins are tailored to reduce your molding cycle time with superior flow properties that enable filling of the mold at lower temperatures.
Among the many features of Crastin® PBT grades are mechanical and physical properties of stiffness and toughness, heat resistance, friction and wear resistance, excellent surface finishes and good colorability. They have excellent electrical insulation characteristics and high arc-resistant grades are available.
Processing is simple, with good flow properties leading to short cycle times using standard injection molding machines. Post-molding operations such as welding, fastening, gluing, printing, painting, hot stamping and laser marking are also easy.
