General-purpose nylon
6/6 has good toughness, tensile strength, and resistance to creep,
particularly in the high temperature range. Nylon has excellent wear properties. low coefficient of friction, and exceptional chemical resistance to aromatic hydrocarbons, greases, and oils. Nylon is a hygroscopic material. Moisture acts as a plasticizer reducing the tensile strength, stiffness, and increasing elongation, impact strength, and energy absorbing characteristics. Outdoor weathering can be improved by the addition of carbon black. Nylon will perform well in long range service in most applications at temperatures as high as 185°F (85°C). Nylon is a translucent off white color. |
