What is delron material?

I'm not aware of a material named "Delron", but there is a material called "Delrin" which is a brand name for an acetal polyoxymethylene resin owned by DuPont. It is a hard resin approved for food handling use by the FDA. It is an economical material with properties of good strength, light weight, and self-lubrication. It is commonly used in the food industry, toys and in paint-ball markers. Grades with higher toughness and strength are used in ski-bindings, gears, and many other applications; typically those which require moderate strength and low-friction.
