Hostaform® polyoxymethylene copolymer (POM)
Available from Celanese Corporation
Hostaform is a highly crystalline engineering thermoplastic resin whose balance of properties and ease of processability offer performance and cost advantages. Hostaform offers high strength and rigidity over a broad temperature range, low wear, toughness (down to –40°C) and resistance to repeated impact. Hostaform products have excellent dimensional stability, long-term creep resistance, long-term fatigue resistance and outstanding resistance to moisture, chemicals and fuels, including fuels with high methanol content.
It can be supplied as unfilled polymer of varying viscosities and as specialty grades that include glass reinforced, impact modified, UV resistant, static dissipative, low wear, and laser markable products. Hostaform XAP (low odor), XF (resistance against hot diesel fuels) and MR130ACS (improved resistance against chlorine and aggressive cleaner), extend the portfolio. Most grades comply with FDA and EU regulations, and drinking water testing has been conducted successfully for standard Hostaform products. Medical technology (MT™) grades that comply with USP Class VI guidelines are excellent candidates for dry powder inhalers, insulin pens and other medical devices, and a Drug Master File (No. 11559) is active.
Applications include: gears, springs, clips and gaskets in fuel system components, toys, washing machines, electric toothbrushes and shavers, faucets and safety belt buckles. Hostaform is also used to produce sheets, rod and slab stock shapes.
