Looking for High-Performance Plastic Components?
PVDF (Polyvinylidene Fluoride) is a semi-crystalline fluoropolymer. Fluoropolymers are great insulators and have hightemperature and chemical resistances. However, they are often soft and susceptible to creep failure. PVDF is a fluoropolymer with relatively high mechanical properties. Typical applications include corrosive environments requiring the chemical resistance of a fluoroplastic, while also needing the higher mechanical properties than a PTFE or PCTFE can provide. It has a long-term service temperature of 300 °F.
PVDF is white in color and is available in a wide range of rod and sheet sizes. It is also commonly used to make tubing or films for insulating applications. It is also inherently non-flammable and FDA compliant and therefore commonly utilized in food processing and chemical processing applications. Its electrical and flame properties have lead to PVDF being commonly used it lithium-ion batteries and for cable jackets as well.
It is easily machined with common metal working equipment. Tolerances of +/-.001 can be achieved with experience
