General Product Descriptions

NYLON

Nylon can replace vastly different materials because nylon's toughness and abrasion ?resistance lie between those of rubber and steel. This combination of properties, rather than ?superiority in any single area make nylon useful for many different applications Most commonly used are Type 6 (cast) and Type 6/6 (extruded). (Note physical differences above.) Nylon generally absorbs more moisture than other bearing materials and therefore may be dimensionally unstable in wet applications requiring close tolerances. Nylon is also available in oil or MoS2 filled compounds which offer a lower cofficient of friction for bearings and wear ?parts. Nylon oil filled offers a much high PV rating.

ACETAL

Acetal is a generic descriptive name for two polymers, Celcon- a copolymer made by Celaness- and Delrin- a homopolymer made by E.I. Dupont De Nemours. Both materials offer ?excellent machining properties and are both dimensionally stable making them ideal for holding close tolerances. The high compression strength and stiffness of acetal also make it a good material for high-load applications. Natural Acetal is USDA/FDA approved.

PTFE

PTFE, has qualities that place it at the top of the scale compared to other plastics and materials. PTFE has the lowest coefficient of friction of any solid known and has high heat resistance, up to 500?F. It is chemically inert, requires no lubrication and is moisture resistant. PTFE is manufactured in many variations, using additives such as glass and chemical compounds to give it specific properties for a particular application.

UHMW-PE

UHMW-PE has one of the highest impact strengths of any thermoplastic. It is abrasion ?resistant, has high tensile strength, displays resistance to stress cracking, and has a good coefficient of friction. It is well-suited where durability and low friction are of paramount importance. Its high resistance to corrosive chemicals, with the exception of oxidizing acids, make it an ideal choice for a wide variety of corrosive environment applications. UHMW-PE can operate successfully at temperatures as low as -375?F making it an excellent material for ?cryogenic applications. UHMW-PE is available in several grades including USDA/FDA approved natural, ultraviolet safe black, and cross-linked, which offers better wear resistance.

POLYPROPYLENE

This material has high impact and chemical resistance. It has a 50% higher temperature rating than UHMW at the same cost. It is also lightweight and dimensionally stable - good for low-cost fabrications.
