Developed in the 1960s for chemical handling and wire insulation and jacketing, Kynar®/PVDF is a registered trademark of Arkema Corp. PVDF stands for polyvinylidene fluoride.
Kynar® / PVDF is a tough, engineering thermoplastic that offers an excellent balance of performance properties. It has the characteristic stability of fluoropolymers when exposed to harsh thermal, chemical and ultraviolet environments.
What are the highlights of Kynar® / PVDF fasteners
- Kynar®/PVDF is a highly non-reactive and pure thermoplastic fluoropolymer.
- Kynar®/PVDF has good creep resistance and weatherability.
- Kynar®/PVDF is currently used in applications requiring the highest purity, strength, and resistance to solvents, acids, bases, and heat. It is known for low smoke generation during a fire.
- Kynar®/PVDF has an easier melt process than other fluoropolymers because of its relatively low melting point of around 177 °C.
- Kynar®/PVDF has a low density (1.78) and lower cost than other fluoropolymers.
- Kynar®/PVDF has a useful temperature range of -148°F to 302°F
- Can be injected, molded, or welded. Used in the injection molding process.
- Kynar®PVDF is commonly used in the chemical, wet bench, modular clean room, medical and defense industries, chemical industry companies, as well as in lithium ion batteries.
- Tensile Strength at Yield by MPa/psi standards 5075-7250 with a Max service temp of 300° Fahrenheit.
