Polyesters, PETP, PBT, PET
Thermoplastic Polyesters are engineering thermoplastics based on PBT (Polybutylene terephthalate) and PET (Polyethylene terephthalate).
Polyester resins combine excellent mechanical, electrical and thermal properties with very good chemical resistance and dimensional stability. Polyesters also offer low moisture absorption and have good flow properties.
The Thermoplastic Polyester product line includes grades that range from un-reinforced to glass reinforced, flame retardant and high flow materials. Specialist Grades are designed to minimise warping, maximise impact strength or optimise surface quality. The range also includes grades for applications that typically require higher strength and or higher heat resistance.
Thermoplastic Polyesters are engineering plastics with excellent processing characteristics with high strength and rigidity for a broad range of applications. Thermoplastic Polyesters have useful properties such as
• Extreme low water absorption.
• Exceptional dimensional stability, due to the low water absorption.
• Excellent electrical properties.
• Excellent resistance to chemical attack.
• High environmental stress crack resistance.
• Very good heat and heat ageing resistance.
• Low creep, even at elevated temperatures.
Thermoplastic Polyesters are easily processed by Injection Moulding, and ProPlastix can advise on all your specific applications.
