Materials › Polybutylene terephthalate (PBT)
The engineering plastic of electrical equipment: connectors, contact carriers, housings. PBT generally absorbs less moisture than the polyamides and has good dimensional stability. Dimensional changes still depend on the grade, the reinforcement, the moulding conditions and the service environment. For hot water and prolonged damp environments, the hydrolysis resistance of the chosen grade has to be assessed.

Brands and manufacturers
Data from producers’ datasheets, medians per family: they are for comparing levels with one another, not guaranteed values. We supply the datasheet of the chosen grade on request.
Real components, not renderings
Parts made in our own plants, with finishing done in-house.
