Acetal Acetal is a tough, stable engineering thermoplastic with a high modulus of elasticity, high strength, good rigidity, dimensional stability, resistance to moisture, solvents and other chemicals. It has very desirable toughness properties, performing well at extreme temperatures and under fatigue endurance. Common applications include precision gears, bearings with close tolerances, electrical engineering insulators, snap fit assemblies, and parts operating in a hot water environment. Acetal has a dynamic (Kinetic) friction coefficient of 0.25 Nylon Nylon plastics are one of the most frequently used thermoplastics for engineering and industrial applications because of their toughness, low coefficient of friction and good abrasion resistance. Nylon plastics can be formulated with a number of different additives to improve load-bearing capabilities and to reduce friction and the need for additional lubrication. Typical applications include rollers, wear pads, gears, nozzles, sound dampening, and sprockets. Nylon has a dynamic (Kinetic) friction coefficient of 0.35 UHMW UHMW-PE (also shortened to UHMW), stand for Ultra High Molecular Weight Polyethylene. It's this extremely high molecular weight that gives UHMW-PE an unsurpassed combination of slickness, toughness and chemical resistance. It's a common plastic encountered every day in the form of food containers and many home appliances. Because of its low coefficient of friction, UHMW-PE is self-lubricating; it replaces unwanted grease and oil in many applications such as bearings and conveyors. UHMW-PE has a dynamic (Kinetic) friction coefficient of 0.07 PTFE PTFE, or Polytetrafluoroethylene, is a fluoropolymer that is resistant to heat and chemicals. It has an extremely low coefficient of friction, and is used as a coating on cookware, gaskets, seals, and hoses. It is unaffected by virtually all acids and caustics, functioning in environments up to 500°F, and as low as -350°F. Virgin PTFE is approved by the Food and Drug Administration for use in the food, beverage, cosmetics and pharmaceutical industries. It is also of great use in laboratory applications because contaminants do not adhere to the surface. PTFE has a dynamic (Kinetic) friction coefficient of 0.12 - 0.15 MSCEASAMPLEPACKS
