New grade of PBT designed for automotive gear housings

DSM Engineering Plastics (Sittard) : 15 December, 2003  (New Product)
DSM Engineering Plastics has introduced a new grade of Arnite polybutylene terephthalate (PBT) designed for automotive gear housings.
Designed for automotive gear housings, a new grade of Arnite PBT exhibits exceptional stiffness, dimensional stability and ductility, while at the same time reducing total assembly costs and weight. This new grade of Arnite PBT closes the performance gap between metal and plastic, thereby offering considerable advantages in weight reduction, design flexibility and assembly costs.

High Performance Arnite PBT was developed specifically to meet the performance requirements of the growing number of electromechanical gear and motor applications in the automotive industry, including wiper, window, cargo and side-door actuation, and moon roof and heating/air conditioning applications. The new resin provides an excellent balance of toughness and high stiffness in elevated temperature applications.

Additionally, high resistance to creep and fatigue, dimensional stability and stiffness are all factors that allow the manufacture of a moulded component that resists distortion, bending or unwanted movement under high-torque conditions.

This new material is a perfect complement to the existing portfolio of Arnite PBT formulations designed for demanding automotive applications.

Arnite is a focused line of thermoplastic polyester engineering materials based on polybutylene terephthalate (PBT) and polyethylene terephthalate (PET). Arnite grades exhibit excellent mechanical, electrical, and thermal properties, as well as good chemical resistance and dimensional stability. The Arnite product line includes unreinforced and glass fibre reinforced grades.

Special grades are designed to minimise warpage, maximize impact strength, or optimise surface quality. In addition to injection moulding grades, the Arnite product line includes various extrusion grades.
