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, 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 (MI)
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®.
Rockbestos-Surprenant will continue to sell under the VITALink brand name for the
Industrial and International markets.
