It offers a high modulus of elasticity combined with great strength, stiffness and resistance to abrasion. Moisture has little or no effect on acetal, and because of this, the dimensional stability of close tolerance fabricated items is excellent. It is suitable for mechanical parts or electrical insulators that require structural strength at above normal temperatures.
Properties:
High modulus of elasticity. High strength and stiffness.
Low coefficient of friction. Easily fabricated with hand
tools and automatic production machinery. Good abrasion
and impact resistance. Low moisture absorption. Excellent
machine ability. Natural lubricant. Resistant to petrol,
solvents, and other neutral chemicals. Useful in air
temperatures of -50°C to +150°C.
Applications:
Acetals overall combination of physical, tribological
and environmental properties make it ideal for many
industrial wear and mechanical applications. Pump and
valve components. Gears, Bearings, Bushings, Rollers,
Fittings, Electrical insulator parts.
