Polybutylene Terephthalate (Pbt)

Features:

PBT blend is engineering plastics
Good creep resistance, very hard ,rigid and strong
High heat-distortion temperature, especially for glass fiber-reinforced grades
Service temperature to 140°C
Very good low-friction and wear-resistant properties
High dimensional stability (low thermal expansion coefficient, low water absorption)
Good electrical properties
Good chemical resistance
No environmental stress cracking
Good weathering resistance
Rapid crystallization and fast cycle time
Paintable
Flame-retardant grades available (UL 94 V-0, in some cases 5VA)

Applications:

Automotive (gear, sensor connectors)
Electrical and Electronics (lamp sockets, connectors, electrometrical components)
Consumer goods (handles and covers of cookers, electrical iron, casing for sandwich toaster)
Fibers in toothbrushes
It is used in the keycaps of some mechanical keyboards
Fluid handling
