Delrin® 525GR NC000 | POM-GF25 | DuPont Engineering Polymers Product Texts
ISO 9988: POM-H,MNR,4-3,GF25
Common features of Delrin® acetal resin 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 colours and speciality grades.
The good melt stability of Delrin® acetal resin normally enables the recycling of properly handled production waste. If recycling is not possible, DuPont recommends, as the preferred option, incineration with energy recovery (-17 kJ/g of base polymer) in appropriately equipped installations. For disposal, local regulations have to be observed.
Delrin® acetal resin typically is used in demanding applications in the automotive, domestic appliances, sports, industrial engineering, electronics and consumer goods industries.
Delrin® 525GR is a 25% glass fibre reinforced, medium viscosity acetal homopolymer for injection molding.
