High Toughness, High Rigidity and Superior Resistance to Heat Aging
PBT is the newest crystalline plastic among engineering plastics, and has high toughness and rigidity, as well as superior resistance to heat aging (it maintains good mechanical properties even under high temperatures).
PBT also has good electrical properties under a broad range of temperatures. It has low water absorption, excellent climate and chemical resistance, and is well-balanced.
Uses
- Electric/electronic devices components
- Automobile components
Characteristics
- PBT can be used continuously at 130°C.
- PBT has good electrical properties.
- PBT has stable dimension changes due to low water absorption.
