DAITHERMO DTK
This environmentally friendly, lead-free polymer bearing material consists of polyetheretherketone resin (PEEK), a superior performing engineering plastic, fiber reinforcing material and a special filler. With the highest heat resistance among thermoplastic resins, PEEK also provides high strength, chemical resistance and excellent sliding characteristics.
Product Details
Features
- Excellent heat resistance (to 260°C).
- Availability of a grade with the same strength as fiber-reinforced type and aluminum alloy.
- Excellent chemical resistance.
- Availability of complex injection-molded shapes.
Major Applications
Automotive parts for brakes, automatic transmissions and air conditioning equipment
Characteristics
| Specific Load MPa | Sliding Speed m/min | Service temp. Range °C (Min. to Max.) | Friction Coefficient μ | Tolerance of Foreign Particles | ||
