PVDF is a kind of fluoroplastic product. It is the abbreviation of polyvinylidene fluoride resin (poly (vinylidene fluoride), which mainly refers to vinylidene fluoride homopolymer or copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer. It has the characteristics of fluororesin and general-purpose resin. In addition to its good chemical resistance, high temperature resistance, oxidation resistance, weather resistance, and radiation resistance, it also has piezoelectricity, dielectric properties, pyroelectricity and other special properties. Performance is currently the second largest product among fluoroplastics, with a global annual production capacity of over 43,000 tons. The application of polyvinylidene fluoride PVDF resin is mainly concentrated in the three major fields of petrochemical industry, electrical and electronic and fluorocarbon coatings. Polyvinylidene fluoride PVDF resin is one of the most important raw materials for fluorocarbon coatings. The fluorocarbon coatings prepared from it have been developed to the sixth generation. Since polyvinylidene fluoride PVDF resin resin has super weather resistance, it can be used outdoors Long-term use, no maintenance, this type of paint is widely used in power stations, airports, highways, high-rise buildings, etc. In addition, polyvinylidene fluoride PVDF resin resin can also be blended with other resins, such as polyvinylidene fluoride PVDF resin and ABS resin to obtain composite materials, which has been widely used in construction, automotive decoration, home appliance shells, etc.
Characteristics and advantages of PVDF screws:
1. PVDF has excellent chemical resistance, excellent resistance to high temperature discoloration and oxidation resistance.
2. PVDF has excellent wear resistance, flexibility, high tensile strength and impact strength.
3. PVDF has excellent UV resistance and high energy radiation.
4. PVDF has poor hydrophilicity.
5. Fluorinated resin (commonly known as thermoplastic Teflon) that can be injected and extruded.
6. Good heat resistance and high dielectric strength.
