Technical Data Sheet: Engineering Plastic Type “DL”
General Notes:
- POM/GF30 acetal resin reinforced with 30 wt% glass fiber.
- Good tensile and flexural strength, fatigue and creep resistance.
- Low friction, good wear and abrasion resistance.
- Low moisture absorption.
- Good chemical resistance (oils, grease, fuels, organic solvents); not resistant to strong acids, alkalis and oxidizing agents; good hydrolytic resistance (hot water).
- Insulating
- Typical applications include handling of very scratch sensitive components (ceramic and glass devices, wafers, capillary)
