NYLON 6/6 POLYAMIDE  (PA)
ZYTEL 101F NC010 (Dry) (PA)
DuPont Engineering Polymers / Americas - Polymide 66
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 185F (85C).
Nylon is a translucent off white color.
