PVDF plastic is widely used in many professions because of its superior characteristics. In the following article, TAELIM will introduce this type of plastic with detailed information for you to understand.
Learn about PVDF plastic
PVDF, whose full name is Polyvinylidene Fluoride, also known as polyvinylidene difluoride (PVF2), is a semi-crystalline fluoropolymer belonging to the thermoplastic group. This type of plastic is notable for its high purity and heat resistance up to 150°C. The structure of PVDF is formed from alternating CH2 and CF2 groups, giving the material unique properties such as insolubility in many solvents and excellent electrical insulation.
The second most popular fluoropolymer after PTFE, PVDF is renowned for its excellent combination of mechanical strength, chemical resistance and processability. PVDF is available in a wide range of melt rates and can be supplemented with additives to optimize its performance in manufacturing processes and industrial applications. This versatility makes PVDF an important material in a wide range of industrial sectors.
