Nylon is the generic designation for a family of synthetic polymers known generically as Polyamides. Nylons offer extremely good wear and impact resistance. They also withstand sustained contact with a wide variety of chemicals and offer a good operating temperature range.Given its relative light weight and toughness Nylon is frequently used as replacement material for metal as gears, fittings, and bearings.Nylon is one of the most widely used engineering thermoplastics. It offers an excellent combination of mechanical performance and cost. Cast Nylon (Type 6) and Extruded Nylon 101 (6/6) are the most common. These manufacturing methods are also combined with various fillers to achieve a number of additional attributes. MDS (molybdenum disulfide -MoS2) and NSM are common solid lubricant filled offerings. Oil filled and glass filled versions are available to provide additional options for lubricity and toughness. Other well-known family members include Nylon-11 and 12.
