Our 2-hour fire-rated polymer insulated cables employ innovative technology that
allows cables to survive and operate during a fire. At the heart of this technology is a
unique silicone rubber insulation material that ceramifies and maintains physical &
electrical integrity when exposed to flame conditions. The product offshoots of this
technology have been designed with practicality in mind. Engineering flexibility & installation
ease features have been maximized to allow for market acceptability.

At Rockbestos-Surprenant, we are proud to announce a new strategic alliance involving
our VITALink line of cables with Tyco Thermal Controls, the global leader in Mineral
Insulated Wiring Systems. In an exclusive agreement, Tyco Thermal Controls will sell
all Commercial and Transit fire-resistant wiring products for North America manufactured by Rockbestos-Surprenant Cable Corporation under the brand name of Raychem®. All International and Industrial fire resistant products manufactured by Rockbestos- Surprenant will continued to be sold under the VITALink brand name.
