General Info

DELRIN® 511P is a homopolymer acetal from DuPont that offers enhanced crystallization characteristics. This higher level of crystallization helps to augment aspects of the physical properties such as fatigue strength, stiffness, and creep resistance.

Note: DuPont discontinued DELRIN® 550 at the end of 2002 and replaced it with DELRIN® 511P.

DELRIN® 511P

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
