Delrin®
This plastic is Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde, Delrin® is a trademark of the DuPont Co. This plastic has excellent dimensional stability after cold working, is relatively tough, while remaining a bit slippery. It is used by Carr lane Mfg. most commonly in applications where impact resistance is not a priority while retaining a non-marking surface.
Nylon
This Thermoplastic was first used in commercial products in the 1930s. Carr Lane Mfg. uses this material in applications where impact resistance or material strength is a primary concern, while retaining the benefits of good dimensional stability, non-marking qualities, and slipperiness.
