- Protects surfaces, gives good electrical insulation, absorbs shock and vibration, and resists corrosion between different metals.
- Nylon has low friction, good wear and creep resistance, and strong resistance to greases, oils and aromatic hydrocarbons.
- Nylon absorbs moisture from its surroundings. Wet nylon loses tensile strength and stiffness but stretches more and absorbs more impact.
Who it helps: Anyone needing an outdoor nylon washer to insulate, protect a surface or separate two metals.
