Big engineering plasticNS902 Polyoxymethylene board
The English name of POM board is Polyxymethylene, commonly known as Saigang, which is a high melting point and high crystallinity thermoplastic engineering plastic. Due to the excellent characteristics of POM, it is very suitable for machining on automatic lathes, especially for manufacturing precision parts.
POM board has high mechanical strength, high rigidity, high hardness, excellent elasticity, sliding and wear resistance, excellent stability, excellent mechanical properties, physiological inertness, and is suitable for contact with food.
POM boards are widely used in fields such as automotive, electronics, clothing, medical, mechanical, and sports equipment.
