Polybutylene Terephthalate (PBT) is a high-performance thermoplastic polyester known for its high strength, heat resistance, and excellent electrical properties. It is similar to Polyethylene Terephthalate (PET) but has lower moisture absorption and better processability, making it ideal for engineering applications.
About PBT
Key Properties of PBT
High mechanical strength and toughness
Provides durability and impact resistance.
Good heat resistance
Can withstand temperatures up to 150–200°C.
Excellent electrical insulation
Ideal for electronic and automotive components.
Low moisture absorption
More stable in humid environments compared to PET.
Good chemical resistance
Resistant to fuels, oils, and solvents.
Dimensional stability
Maintains shape under stress and temperature changes.
Fast crystallization
Allows for shorter molding cycles and high productivity.
Available JEDA Options
Common Applications of PBT
Automotive Parts
Connectors, ignition system components, sensors
Electrical & Electronics
Switches, sockets, circuit breakers, insulation parts
Industrial Machinery
Gears, bearings, conveyor components
Consumer Appliances
Hairdryer housings, coffee machine parts, kitchen appliances
Medical Devices
Surgical instruments, diagnostic equipment
Performance Overview
PBT is often reinforced with glass fibers for added strength and heat resistance. Compared to PET, PBT has lower melting temperature and better processability, making it faster to mold while still offering excellent durability and insulation properties. However, it has lower stiffness than PET and may degrade under UV exposure without proper stabilization.
