PBT Compounds
Material overview
Polybutylene terephthalate is a thermoplastic polyester with good mechanical strength, heat resistance, electrical performance and dimensional stability. PBT is commonly modified with glass fiber, mineral fillers and flame-retardant systems to meet the requirements of automotive, electrical and electronic, appliance and industrial applications.
Key properties
-
Good strength and toughness for mechanically loaded components.
-
Good thermal performance and dimensional retention at elevated temperature.
-
Resistance to oils, fuels, acids, alkalis and many industrial chemicals.
-
Good electrical insulation and dielectric performance, including in humid environments.
-
Low shrinkage and good dimensional accuracy for precision molded parts.
-
Good wear performance and low friction for selected mechanical components.
Typical applications
-
Automotive lighting, electrical connectors, handles and under-hood components.
-
Electrical connectors, sockets, switches, housings and cable-related components.
-
Heat-resistant appliance components.
-
Gears, bearings and pulleys.
