Physical and mechanical characteristics of Nylon

What is...

Nylon 6/6 Polyamide (PA)

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 particularly to aromatic hydrocarbons, greases and oils.

Nylon is a hygroscopic material. Moisture acts as a plasticiser 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 85°C. Nylon is a translucent off-white colour.
