POM-C (Polyoxymethylene Copolymer)
4.8 (186 Reviews) 9058 orders
Material type: Plastic, Weather resistant
POM-C (Polyoxymethylene Copolymer) is a semi-crystalline engineering plastic that offers self-lubricating properties, low friction, and excellent wear resistance. It also features good dimensional stability, low water absorption, resistance to hot water and alkaline media, high rigidity, and excellent machinability via CNC. Its disadvantages include poor bondability and susceptibility to strong oxidizing agents. It is suitable for precision sliding applications and structural components in humid environments, such as slider blocks, gears, bushings, and cams in automation equipment, as well as fluid valve parts and wear-resistant transmission components in food machinery.
