Teknor Apex Company has developed four new PVC jacket compounds to meet flame test requirements for power and control tray cables. Apex ® 70018 is a 73 Shore A PVC compound for soft, low gloss, highly flame-retardant jacketing for use over polyethylene, suitable for indoor applications. The material is capable of achieving UL oil resistance I and II ratings, and has a brittle point of -16°C. Apex 70020 is a 79 Shore A PVC compound for outdoor-rated jackets over crosslinked polyethylene. It is capable of Oil I and II ratings and is designed to pass -25°C cold impact and -40°C cold bend tests. Apex P-55007 is an 82 Shore A blend of PVC and thermoplastic polyurethane (TPU) formulated for use in appliance wiring and tray cables over polyethylene cores. This is the most flame-retardant of a series of PVC/ TPU blends. Flexalloy ® 9627-79 is a 67 Shore A PVC elastomer developed as a spatter-, oil- and UV-resistant material for welding cable. It meets the UL-62 standard for flexible cable and is for use over PVC or crosslinked polyethylene cores. All four compounds pass requirements for UL-1277 (electrical power and control tray cables with optional optical fiber members) and UL-13 (power-limited circuit cables); meet the CSA FT-4 burn tests with appropriate cores; and have a maximum continuous operating temperature of 105°C.
