General Information
Consider Celcon® Acetal copolymer if your design requires wear resistance, high flexural fatigue strength, toughness and creep resistance.
Celcon® Acetal copolymer is comparable to Delrin® & Hostaform® POM and offers high strength and rigidity over a broad temperature range, low wear, toughness and resistance to repeated impact. These products are notable for their superior dimensional stability, long-term creep resistance, long-term fatigue resistance and excellent resistance to moisture, chemicals and fuels, even oxygenated fuels and gasohol. Celcon® products are used extensively in injection molding and are also readily processable by other conventional techniques such as extrusion, compression molding, rotational molding and blow molding. In addition, Celcon® Acetal copolymer is suitable for 2-component hard-soft molding with thermoplastic elastomers, including SEBS, a styrene based elastomer.
Celcon® Acetal copolymer can be supplied as unfilled polymer of varying viscosities and as specialty grades which include glass reinforced, impact modified, UV resistant, low gloss, static dissipative, low wear, bleach resistant and laser markable products. Certain specialty grades offer outstanding properties for fuel and plumbing applications. Celcon® grades that comply with FDA, UL and NSF are available. 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.16661) has been created. All Celcon® products are available in a wide array of colors which do not contain heavy metals i.e. Cd, Hg, Pb, Cr(VI), and virtually all colors can be matched.
Due to their versatility, Celcon® products are used in numerous applications such as gears, springs, clips, snap-fits, knobs and gaskets for fuel system components, toys, washing machines, hand tools, shower heads and seat belt buckles. Celcon® is also used to produce sheets, rod and slab stock shapes that can be machined to tight tolerance.
