It’s more than acetal – it’s DuPont™ Delrin®.
Unlike acetal copolymers, Delrin® is a tough, lightweight and durable acetal polymer with inherent low friction, low wear, low noise, low moisture pick-up and excellent spring back properties, invented by DuPont.It's so well known that the brand name Delrin® is often misused as the industry term for acetal resin. But, not all acetals are equal.
How is Delrin® different?
Delrin® is an acetal homopolymer and has a uniform backbone with a larger crystalline block structure than acetal copolymers providing better chemical bonding. As a result, Delrin® is the stiffest and strongest unreinforced technical engineering polymer available.
Delrin® offers major benefits over acetal copolymer
Specifying Delrin® for highperformance, high precision mechanical parts can allow to optimize part design and production :
Mechanical properties comparison
For example, Delrin® 500P, our general purpose resin, significantly outperforms general purpose acetal copolymer across the entire mechanical spectrum:
