Polyvinylidene fluoride (PVDF) or polyvinylidene fluoride (PVDF) is a highly unreacted thermoplastic fluoropolymer formed from the polymerization of vinylidene fluoride.
PVDF is a special plastic for applications that require the highest purity and resistance to solvents, acids and bases. Compared to other fluoropolymers, such as polytetrafluoroethylene (Teflon), PVDF has a low density (1.78 g/cm 3).
It can be used as high-end wire pipe products, sheets, tubes, films, sheets and insulators. It can be injected, cast or welded and is commonly used in the chemical, semiconductor, medical and defense industries, as well as in lithium-ion batteries.
It can also be used as a crosslinked closed foam and is increasingly used in aerospace and aerospace applications. It can also be used for repeated contact with food because it meets FDA standards and is completely non-toxic.
As a fine powder, it is a component of metal advanced coatings. These PVDF grades offer excellent gloss and color retention.
They are used in many well-known buildings around the world, such as the Petronas Towers in Malaysia and Taipei 101 in Taiwan, as well as commercial and residential metal roofs.
PVDF films are used in western blotting to stabilize proteins due to their non-specific affinity for amino acids.
PVDF is also used as an adhesive component for carbon electrodes in supercapacitors and other electrochemical applications.
Therefore, in the construction and building materials industry, aluminum color has diversified and improved products before competing in the market, used in many different categories of works, from walls, walls, roofs to decorative advertising art pieces.
Color coated aluminum as a protective coating on the surface of buildings requires high durability and good environmental resistance, especially in the Marine environment.
The decisive factor of quality, in addition to the basic components are high-quality aluminum and durability, but also depends on the surface paint must have strong protection, good corrosion resistance and color fastness, resistance to chemical changes in the weather and environmental pollution.
Coatings are surface elements that interact directly with external factors, so coating systems play an extremely important role in protecting the inner layer from harsh tropical weather conditions.
In order to ensure the role of the coating, high-quality aluminum coatings must be guaranteed to prevent the phenomenon of cracking and fading of the coating, which is common in hot and serious Asian countries.
In the face of increasing climate change, external factors from the environment include hot sun, ultraviolet light, dirt, acid rain and many other causes of pollution. The coating now acts as a shield for the aluminum layer, as well as an environmental etchant for the beauty of the previous work.
Without good protection, these agents will gradually erode the paint and eventually destroy the entire structure of the aluminum layer. PVDF is an exclusive topcoat for aluminum and is intended for outdoor use for at least 10 to 20 years.
For color coated aluminum for civil and industrial applications, the requirements for coating systems vary from acrylic or polyester to super polyester and high quality coatings.
The variety and quality of polyvinylidene fluoride coatings allows the aluminum plating market to shape many quality segments from low to high.
