Crastin SF PBT Polyester Resin

DuPont™ Crastin® PBT thermoplastic polyester resins are based on polybutylene terephthalate. By making physical and technical modifications, a very wide range of products is available that are ideally suited to an enormous variety of industrial applications, including electronics, electrical, automotive, mechanical engineering, chemical and apparatus engineering, domestic and medical appliances and sporting goods. In fact, this growing family is currently available in over 30 different grades, approximately half of which are flame retardant. New Crastin® SF PBT products use a technology to enhance flow of the resin to extremely high levels:

• Crastin® SF dramatically reduces manufacturing costs
• Improving productivity by up to 30%
• Reducing machine size thanks to lower filling pressure
• Reducing part thickness under standard filling conditions
• Lower energy consumption
• Wider processing window
• Lower reject rate
• Improved flow to fill moulds for thinner or more complex parts than standard PBT grades
• Crastin® SF offers excellent property retention: stress, strain and impact, thermal stability and more
• Crastin® SF is a direct drop-in replacement for standard PBT grades
