Nylon sheet which has not been compounded with UV stabilizers are sensitive to ultraviolet light. These compounds should not be used for extended outdoor service. Carbonblack (our black Nylon Sheet) is the most effective of the UV stabilizers. These additives also increase tensile strength and hardness and decrease ductility and toughness slightly.
