For applications where higher temperature endurance is not needed, Cable USA offers a selection of flexible cable jackets including polyurethanes (very tough!) as well as Low-Smoke, Zero Halogen (LSZH) materials with temperature ratings from 80C through 125C.
The most popular material with this temperature rating is ETFE (aka Tefzel™). Not only is it excellent in chemical environments, it’s also very tough and functional at low temperatures down to -100C as well.
Several choices exist for 200C applications, including FEP Teflon™, Tefzel™ 750 (a higher-rated ETFE polymer), and silicone rubber. The fluoropolymers are highly chemical resistant as well as applicable in thinner walls to make them more affordable.
The preferred extrudable material for 250C applications is PFA, which (in addition to FEP attributes) is available in extremely long continuous lengths – differing in that regard from other 250/260C types of Teflon™. Also, mineral (mica/glass) insulated wire is also available at this rating, usually used for heater applications.
ECA™ extruded wire is now available for 300C applications, offering the same great chemical resistance and toughness as other fluoropolymers combined with the easy installation of an extruded wire.
For applications requiring temperature resistance up to 450C (and more), we offer high-performance mica/glass insulated products. These are great for direct connection to heater elements and other extreme temperature environments.
