Kynar® PVDF: A broad range of properties useful in a variety of markets
Kynar® and Kynar Flex® fluoropolymer resins offer a wide range of extreme properties to suit the most demanding needs of the wire & cable industry.
Kynar® resins retain excellent physical properties in adverse chemical and thermal environments allowing them to be used when more flexibility and toughness are required. The chemical resistance of Kynar® and Kynar Flex® PVDF resins allows for use in corrosive chemical, acid and extreme temperature environments. Kynar® resins also provide exceptional abrasion resistance, excellent UV resistance, inherent flame resistance, and low smoke generation.

Kynar® PVDF Flame, Smoke and Heat Resistance
The excellent flame, smoke, and heat resistance properties of Kynar® PVDF are naturally achieved through its chemical structures, requiring no additives. Virgin Kynar® resin does not easily burn and will self-extinguish when the flame source is removed making it ideal for building plenum applications. Its high mechanical strength, abrasion resistance, and cut-through resistance allow Kynar® PVDF to maintain the integrity of the cable insulation and to withstand the abuses during the installation of plenum cable. In addition to fire performance, many grades of Kynar® PVDF are rated at 150°C RTI and are NYC Local Law 5 Compliant.
The inherent fire performance of Kynar® PVDF can be further improved by modifying the polymer. These constructions generate almost no smoke and no flame spread when tested to UL 910/NFPA 262, UL 2024 and NFPA 255 methods.

Application Focus: Heating Cables
Heating cables face exposure to chemicals, mechanical forces from installation, and a broad range of temperature fluctuation from -60°C to 150°C. Kynar® PVDF resins have excellent abrasion resistance and flexibility allowing for ease of installation, and Kynar® resins have the widest flexibility range of all the fluoropolymers allowing them to fit a variety of heating cable designs. Additionally, select Kynar® PVDF grades can operate continuously from -60°C up to 150°C. Kynar® PVDF is not degraded from concrete or other chemistries present during installation.
Application Focus: Industrial Cables
Industrial cables are subject to millions of flex cycles, elevated temperatures, factory oils and greases, abrasion, and stray welding sparks. Kynar® PVDF resins are ideal for industrial cable jackets because they have excellent flex fatigue resistance. The flexible nature of the Kynar® resin is inherent to the copolymer and it does not require any plasticizer which could leach out over time and compromise flex fatigue resistance. Kynar® PVDF has excellent flame and smoke performance, and plenum rated packages are available as well. Kynar® PVDF resists incidental contact with oils, hydrocarbons, and most solvents, and it is robust as an outer jacket so that it does not get abraded away if dragged upon the ground during or after installation.
Application Focus: Kynar® UHM for Connector Housings
For high performance cable connector designs requiring the mechanical strength of PEEK but with a lower temperature requirement, (up to 150°C) Kynar® UHM can be used which will significantly save on raw material costs. With a tensile modulus around 1,000,000 psi, Kynar® UHM is extremely rigid and dimensionally stable, ideal for tight tolerance molded parts. It maintains excellent chemical resistance, and burn performance.
