High quality PBT/PET injection virgin grade glassfiber filled

Short Description:

Material plastic PBT/PET has the characteristics of good heat resistance, low moisture absorption, good chemical resistance, good weather resistance, high dielectric strength, good electrical properties, high dielectric strength and dimensional stability. And it is easy to be made to glass fiber reinforced or flame-retardant products, which can be ultrasonically welded and easily processed. And they are widely used in the fields of electrical and electronic, mechanical and chemical, automotive, etc.

Product Detail

Product Tags

PBT/PET is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. It is a thermoplastic (semi-)crystalline polymer, and a type of polyester. There are resistant to solvents, shrinks very little during forming, is mechanically strong, heat-resistant up to 150 °C (or 200 °C with glass-fiber reinforcement) and can be treated with flame retardants to make it noncombustible. It was developed by Britain's Imperial Chemical Industries (ICI).

PBT is closely related to other thermoplastic polyesters. Compared to PET (polyethylene terephthalate), PBT has slightly lower strength and rigidity, slightly better impact resistance, and a slightly lower glass transition temperature. PBT and PET are sensitive to hot water above 60 °C (140 °F). PBT and PET need UV protection if used outdoors, and most grades of these polyesters are flammable, although additives can be used to improve both UV and flammability properties.

PBT/PET Features

Good heat resistance, super toughness& fatigue resistance.

Nice electrical stability.
