Copolymer coated steel tape is a type of steel tape commonly used for cable armoring. The steel tape is coated with a layer of copolymer, which provides excellent adhesion between the steel tape and the outer jacket of the cable. This helps to prevent moisture and other contaminants from entering the cable, which can lead to degradation and failure over time. The copolymer coating also provides additional protection against abrasion and impact, making it ideal for use in harsh environments. Additionally, the steel tape provides mechanical strength to the cable, enhancing its overall durability and resistance to damage.
