TDI Delrin Fiber Specifications

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, SMD, wafers)
