AlfaBondĀ® Coated Copper

AlfaBond® coated copper consists of a copper tape coated onone side with an adhesive ethylene copolymer. The composition of the copolymer is exactly the same as that developed by The Dow Chemical Company for coated copper and maintains its bond strength when exposed to moisture. The peel strength is maintained after accelerated water aging when tested according to ASTM B736. The bond strength to the jacket is maintained when cableis tested according to the corrosion test that is part of the recommendations ofCIGRE Study Committee 21. The copolymer exhibits excellent adhesion to the copper substrate and to the low, linear low, medium and high density polyethylene jackets, or over-sheaths, used for cable applications. The copper meets the requirements of ASTM B 694 for electrical grade copper, 99.9% pure.
