POM

Polyoxymethylene (polyacetal)

POM is stiff, slippery and fatigue-resistant thanks to its high crystallinity, making it the first choice for self-lubricating gears and mechanisms. Copolymer grades resist hot water and chemicals better than the homopolymer. It does not absorb moisture and stays dimensionally stable; it works well in snap-fits and latches that need spring.

Overview

POM is the standard grade of the POM family in the engineering plastics group. It is used in applications such as gears, cams and mechanism parts, zippers, clips and buckles, fuel-system and pump parts. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

  • Fuel-system and pump parts
  • Tap, valve and water-meter parts

Industries: Appliances and small domestic appliances, Furniture and consumer goods

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for POM are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
