In present work, a large-scale test rig has been used for determinating friction of a commercial polyoxymethylene homopolymer (POM-H). GF20215976 (acetal - homopolymer POMH), film, thickness 0. POM homopolymer is a semi-crystalline polymer (75–85% crystalline) with a nominal melting point of 175 °C. View Pricing. It is a lightweight, low-friction and wear-resistant material with good physical and processing properties. On the contrary, thermoplastics have a different response to heat. Thermooxidative degradation at and beyond processing temperatures of a polyoxymethylene copolymer has been progressively accelerated to carbonisation through oven-storage aging. 5 mm, size 150 × 150 mm; Synonyms: OX311050; find -GF44042352 MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich The hemiformal is then heated to release the formaldehyde, and the formaldehyde is polymerized by anionic catalysis. 2 As with any material, some characteristics.
