Chemical Structure
-
Features:
1. Mechanical Properties: High strength, fatigue resistance, dimensional stability, and minimal creep (very little change even under high-temperature conditions).
2. Heat Aging Resistance: The enhanced UL temperature index reaches 120-140°C (excellent long-term outdoor aging resistance).
3. Solvent Resistance: No stress cracking.
4. Water Stability: PBT is not easily decomposed by water at room temperature (caution is needed when used in high-temperature and high-humidity environments).
Applications:
Electronics and Electrical Appliances: Connectors, switch components, household appliances, accessory parts, small electric motor covers (known for heat resistance, flame retardancy, electrical insulation, and moldability).
Automotive:
(1) Exterior Parts: Includes corner guards, engine cooling hole covers, etc.
(2) Interior Components: Involves interior mirror support strips, wiper blade brackets, and control system valves.
(3) Automotive Electrical Components: Includes ignition coil winding tubes and various electrical connectors.
