Applications > Wire and Cable
The portfolio of elastomer products for the wire and cable industry meet virtually all jacketing requirements in the low and medium voltage category.
Today, the lineup includes DuPont™ Neoprene polychloroprene, DuPont™ Viton® fluoroelastomer and DuPont™ Viton® FreeFlow™. Individually, each offers a unique performance profile. Collectively, they represent the broadest selection of synthetic elastomers from one company.
DuPont™ Vamac® ethylene/acrylic elastomer has exceptionally low smoke emission characteristics. When properly compounded with a sufficient amount of hydrated alumina, compounds of Vamac® offer an excellent combination of properties for low smoke, flame retardant cable jackets.
Widely used as protective cover for cables since the 1940s, Neoprene polychloroprene provides many of the attributes of natural rubber in jacketing but with significantly better heat, ozone-corona, weather, chemical, oil and flame resistance. Applications include jacketing for lead press cured black mining cables, and heavy-duty and extra heavy-duty cables. In addition, the outstanding physical toughness and exceptional resistance to flex cracking and abrasion of Neoprene leads to improved cable performance and service life.
During the manufacture of jacketing for wire and cable, die build-up can develop. The deposits on the die aversely affect production rates and surface quality. The use of Viton® FreeFlow™ reduces die build-up, improves processing and surface finish with no effect on performance including electrical properties or permeability.
Viton®, the world's first and leading fluoroelastomer, delivers exceptional performance in low voltage insulation and jacketing, being particularly resistant to high temperatures and aggressive fluids. Viton® can be crosslinked at high and low temperature and by irradiation.
