What is PVDF?
PVDF stands for polyvinylidene fluoride. It is a part-crystalline food-approved thermoplastic, notable for its good chemical resistance.
PVDF is supplied in sheets and rods in a natural colour.
Several companies produce PVDF, and the material is known under several brand names such as TECAFLON™ og Symalit®.
The characteristics and advantages of PVDF
![Overview of the characteristics of PVDF plastics](/media/qvqdd5dw/pvdf_uk.jpg?cc=0.02471836419753087,0.019496945399007256,0.019726080246913375,0.024947499045437048&width=1140&height=485&v=1dabd631eeb4cc0)
PVDF is a material with a high operating temperature and high density at 1.78 g/cm3. In other words PVDF is one of the heavier construction plastics, only exceeded by PFTE, which has density at 2.18 g/cm3.
Furthermore water absorption is low, strength is high, and qualities of gliding and wear are good, allowing it to perform in exacting environments over a long service life.
It possesses good chemical resistance and high UV-resistance.
In certain applications, PVDF can be subject to cold flow.

PVDF applications
Due to the good chemical resistance against alkaline substances, for instance, PVDF can be especially useful in withstanding harsh cleaning agents: examples are the medical and dairy sectors.
PVDF is often used in environments with relatively high operating temperatures (up to 150 °C) and where there are requirements for low water absorption.
The material is also useful in environments exposed to UV.
PVDF is suitable in products such as:
- Pump parts
- Valves
- Gaskets
- Fittings
