| DUPONT DELRIN® SUPERTOUGH ACETAL - 100ST (IMPACT MODIFIED) | ||
| DELRIN® 100ST NC010 | ||
| DuPont Engineering Polymers / Americas - Acetal (POM) Homopolymer | ||
| Delrin® acetal resins are thermoplastic polymers made by the polymerization of formaldehyde. Delrin 100 is a high viscosity resin, which shows outstanding physical properties, especially toughness. Delrin is noted for high strength and rigidity in a wide temperature range, fatigue endurance, excellent resistance to moisture, gasolines, solvents, and many other neutral chemicals. High resistance to repeated impacts, resilience, it also has a good wear resistance and low coefficient of friction. | ||
| APPLICATIONS | ||
| Delrin® can be used in automotive, appliance, plumbing, construction, hardware, electronics, and consumer goods. | ||
