GEHR Plastics PBT® Polybutylene Trephthalate
Categories:	Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT)
Material Notes:	Extremely high toughness allows the use of self tapping screws or inserts. The good sliding properties and the high dimensional stability also open up a wide range of possible applications. Very good results can be achieved in joining processes with two component adhesives on the basis of e.g. epoxy resins or cyanoacrylates as well as silicones. Painting of the part or high vacuum coating of the component surface is also possible. The continuous operating temperature ranges from approx. -60°C to 100°C. Properties: high stability, stiffness and toughness even at low temperatures, good creep resistnac, high surface hardness, good polishability, high dimensional stability, easy to metalize, good sliding proerties, good electrical insulation characteristics, high resistnace to chemicals, easy to paint, good UV and weather resistance, sensitive to hydrolysis. Applications: components with metal inserts, pump components, housing components, tankk caps, gear wheels, insulation parts in electrical engineering, applications with UV exposure. information provided by GEHR
