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)
