These are manufactured using ultra-violet (UV) stabilized grade of HDPE with required Antioxidant content is another recommended additive. The inner layer of ducts is duly silicon coated which minimize the friction b/w OFC and the duct during the process of blowing the cable into the ducts, thus providing smooth installation of OFC in the duct without damaging the cable fibers.
