You Are buying 245 mm / 24.5 cm Le
ngth Polyacetal H
The Acetal Rod is a high strength, temperature resistant,
highly crystalline thermoplastic with a high melting point.
Low coefficient of friction, good abrasion resistance, and dimensional c
stability make it suitable for machining as per nylons, having much
lower moisture absorption. Ideally suited for electrical insulators
requiring exceptional structural strength at high temperatures or
moisture conditions and for machining mechanical parts.
Polyacetal H is quadrant's homopolymer acetal grade.
It offers a higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate and ofter also a better wear resistance than acetal copolymer.
