Choose from two material types; 1. NATURAL NYLON 6/6 Primarily used in indoor applications. Life expectancy in ultraviolet light, (sunlight), is one to two years*. The normal operating temperature range of nylon 6/6 is -10°c to 85°c. 2. BLACK WEATHER RESISTANT NYLON 6/6 Primarily used in outdoor applications. Over a period of time, ultraviolet light attacks most plastic materials and reduces their properties by breaking down the molecular chain. A uniform dispersion of 2% carbon black provides UV resistance and increases the cable tie life expectancy to 7-9 years*.
