Description

Common features of Delrin® acetal resins include mechanical and physical properties such as high mechanical strength and rigidity, excellent fatigue and impact resistance, as well as resistance to moisture, gasoline, lubricants, solvents, and many other neutral chemicals. Delrin® acetal resins also have excellent dimensional stability and good electrical insulating characteristics. They are naturally resilient, self-lubricating, and available in a variety of colors and speciality grades. Delrin® acetal resin typically is used in demanding applications in the automotive, domestic appliances, sports, industrial engineering, electronics, and consumer goods industries.Delrin® 511CPE is a medium viscosity acetal homopolymer with enhanced crystallization for faster cycle times, excellent creep and fatigue resistance, and very low VOC emissions.Delrin® 511CPEprovides improved thermal stability, excellent dimensional stability, low warpage, fewer voids, and improved productivity for injection moulding.
