1. mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (high temperature conditions rarely change);2. heat aging: enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term aging is also very good);3. solvent resistance: no stress cracking; water stability: PBT is not easy to break down with water;4.electrical performance: -- Insulation: Excellent (humid, high temperature can also maintain electrical stability, is the ideal material for the manufacture of electronic and electrical parts); --dielectric coefficient: 3.0-3.2; -- arc resistance: 120s5. molding processability: ordinary equipment injection molding or extrusion.As the crystallization speed, good fluidity, mold temperature is also lower than other engineering plastics requirements. In the processing of thin-walled parts, only a few seconds, only 40-60s for large parts can be. Application1,Electrical and electronic industry: connector, timer, reel, cover circuit breaker, transmission wheel, cable rack, etc2.Automobile industry: intake manifold, engine cover, engine decoration cover, cylinder head cover, oil filter, wiper, radiator grille, fuel pipe, etc3.Sports equipment: bicycle cushion, wheel hub and wheel, bicycle handle and zero accessories, skate accessories, etc
