- Window regulators, seat belt systems, and lock systems – lightweight with high strength.
3. Electrical & Electronics
- Insulating parts, switch components, and connectors – because of good dielectric strength and low moisture absorption.
- Cable ties and coil bobbins – provide strength + stability in varying conditions.
4. Food & Beverage Machinery
- Conveyor components, sliding guides, star wheels, cutting boards – food-safe grades are FDA approved.
- High hygiene applications due to low moisture absorption and easy cleaning.
5. Textile & Packaging Machinery
- Wear strips, rollers, guide rails – excellent abrasion resistance and dimensional accuracy.
- Used in high-speed machinery due to low friction.
6. Chemical & Pump Industry
- Pump housings, impellers, valve seats, seals – resistant to many solvents, oils, and weak acids/alkalis.
- Reliable in wet conditions due to low water absorption.
7. Precision Instruments & Medical
- Measuring instruments, dental devices, medical housings – Delrin-C is dimensionally stable and can be sterilized (in specific grades).
8. Construction & Industrial Equipment
- Sliding pads, hinges, handles, and machine covers – high strength + long-term durability.
- Replaces metals in many structural parts to reduce weight.
Engineering Advantages of Delrin-C Sheets:
