Nylon is noted for its low friction and good chemical resistance. Its polymer structure, with flexible chains and semi-crystalline regions, reduces surface wear and lets it form a thin lubricating layer in contact parts, so moving components like bearings and gears run with less resistance. It also resists many oils and solvents, making it durable in chemical environments. It isn’t extremely heat resistant compared with some high-temperature plastics and it’s not a good conductor of electricity, since polymers are generally electrical insulators. So the combination of low friction and chemical resistance best fits nylon’s well-known behavior.
