Delrin® 500CPE NC010
Sold by DuPont
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® 500CPE (DE20729) is a medium viscosity acetal homopolymer with very low VOC emissions for applications in automotive interiors. It provides good mechanical performances with improved processing, thermal stability and productivity for injection molding.
