Formula: POM-C
Form: Rod
Material: Polyoxymethylene Copolymer (POMc)
Commodity: Polymers
As part of our extensive range of plastic rods, POM Copolymer Rods are made from a highly engineered thermoplastic and available in 115 variations. POM Copolymer combines stiffness, strength and dimensional stability with inherent lubricity and abrasion resistance. It also has low moisture absorption, making it suitable for applications like gears, rollers and bushings that require tight tolerances. In addition, its chemical resistance makes it ideal for food processing equipment and medical devices. The many options of these versatile POM Copolymer Rods enable tailoring to specific engineering needs across industrial, scientific and medical settings.
