(a) Nylon
Nylon offers good insulating properties plus resistance to heat, shock, vibration and chemical solvents Also nylon possesses lightness elasticity and superior torque strength Nylon 6/6 is used for 80
or 9O% of all nylon fastener applications. Nylon 6/10 is used for ultraviolet
applications or where high temperatures are Involved Nylon should not be used in mineral acids Also, nylon should be carefully considered for use
in direct sunlight application because It has a tendency to oxidize and
embrittle.
(b) PVC
Used for outdoor weathering, and applications where there are high concentrations of mineral acids The prime reason PVC fasteners are
used in industry is because of their corrosion resistance to acids.
