What is PVDF

PVDF, Polyvinylidene Fluoride, is a type of polymer plastic material. Polymer materials consist of long-chain molecules formed through the polymerization reaction of repeating monomer units. Many natural materials we encounter are composed of polymers, such as natural rubber, cotton, and human organs. Artificially synthesized chemical fibers, plastics, and rubbers are also made this way.
PVDF is produced through the polymerization reaction of vinylidene fluoride monomers. The molecular structure of PVDF endows it with a series of excellent properties, including chemical stability, heat resistance, mechanical performance, and durability, making it widely used across various industrial fields.

Chemical and physical properties

PVDF possesses excellent chemical stability and exhibits outstanding resistance to most chemicals and solvents, making it an ideal material for pipes and containers in the chemical industry. In terms of temperature resistance, PVDF can operate over a long period within a temperature range of -30°C to 150°C, and certain special grades of PVDF can even withstand higher temperatures. Additionally, PVDF has superior tensile strength and impact resistance, suitable for applications requiring high durability. Common industrial applications of PVDF include its use as a binder or coating material in solar panels and lithium batteries, enhancing the performance and lifespan of the products. Due to its exceptional purity and chemical stability, PVDF is frequently used in semiconductor processes to manufacture pipes and container materials.
