Injection Molded Products Gear TI grade
TI-5000 Series (PAI: Polyamide-imide)
Superior Balanced Physical Properties and Optimal for Heat-Resistant Gears
The TI-5000 Series boasts superior heat resistance (continuous use temperature of 250°C), heat distortion resistance (deflection temperature under load of 279°C), mechanical properties (especially tensile strength and shock resistance), fatigue resistance, flame retardance, friction and wear resistance, and stress crack resistance.
Characteristics
- (1) The TI-5000 Series demonstrates a superior balance of heat resistance and strength.
→ Its strength lends itself to preventing cracks in gear tips or welding. - (2) It demonstrates high strength even without reinforcement from glass fibers as well as superior abrasion resistance.
→ This property prevents any damage to itself or to other materials (for example, contact gears or internal shafts) - (3) This series demonstrates superior dimensional stability.
→ The linear expansion coefficient is minimal, and precision is high.
The TI-5000 Series “exceeds the performance of traditional engineering plastics in almost all aspects.”
TI-200 Series (PPS-based)
A Series with High Heat Resistance and Strength for Those Looking for a Low-Cost Option!
The TI-200 Series is based on PPS resin, which offers superior heat resistance and flame retardancy, strengthened with special fibers. Its favorable moldability lends itself well for manufacturing with reliably high accuracy. The combination of high-strength grade TI-250A and sliding grade TI-200C not only gives this series low self-abrasion, but it also lowers the abrasion with other materials under extreme usage conditions of high temperature and high torque.
