Plastic Sheet, Rod & Tube

Plastic Machining Company uses high-quality UHMW, nylon, and acetal plastic sheet, rod and tube from manufacturers including Quadrant Engineering Plastics, Cast Nylons, Ensinger, Rochling and other resin converters.

Nylatron GS Nylon Plastic SheetThe same high-quality materials we use for our components may be purchased as semi-finished plastic sheet, rod and tube. See our selection below; standard sheet size and rod/tube length depend on the material and material grade.

Comparing nylon, UHMW & acetal: Both nylon and UHMW plastics feature low friction, self-lubricating grades and long life in high wear applications.

Nylon comes in FDA compliant grades for food processing machinery and has a higher tensile strength as well as a higher ratio of stress to strain in flexural deformation.

UHMW features higher impact strength with more resistance to chemicals. It also has high abrasion resistance and near-zero water absorption.

Copolymer acetal and homopolymer Delrin® offer low moisture absorption (not quite as much as UHMW) and desirable chemical resistance. In addition, it has higher mechanical strength, rigidity and dimensional stability (change resulting from exposure to varying temperature).

Dimensional stability is a consideration in strict tolerance part applications where little to no expansion of the material is required. Acetal / Delrin is stronger than both UHMW and nylon plastics.

UHMW plastic, nylon plastic, and acetal / Delrin plastic all carry the advantage of resisting moisture, with near zero water absorption, while also resisting harsh chemicals and contaminants. Plastic power transmission parts do not rust like many metals and survive in the harshest of environmental conditions.
