Description
Black acetal copolymer (POM-C) round bar from 50mm to 220mm diameter, in lengths from 500mm to 3000mm. Acetal is one of the most popular engineering plastics for machined parts: stiff, strong, low-friction and dimensionally stable, and it machines to a clean, accurate finish. The black grade hides wear marks and is a good choice for parts exposed to daylight.
- ✔ Low friction and excellent wear resistance – ideal for sliding and rotating parts
- ✔ Stiff, strong and tough, with good fatigue resistance
- ✔ Low moisture absorption – holds tight tolerances where nylon would swell
- ✔ Machines beautifully – turns, mills, drills and taps to a smooth finish
- ✔ Good chemical resistance to oils, fuels, solvents and many detergents
