Polyvinylidene fluoride. Polyvinylidene fluoride; PVDF

PVDF is a semi-crystalline polymer with a crystallinity of about 50%. So far, there are five crystal types, α, β, γ, δ and ε, which are formed under different conditions and can be transformed into each other under certain conditions (heat, electric field, mechanical and radiation energy). Among these 5 crystal forms, β crystal form is the most important, and PVDF for piezoelectric and pyroelectric applications mainly contains β crystal form.

property

White powdered crystalline polymer. Density 1.75-1.78g/cm3. Glass transition temperature -39℃, embrittlement temperature -62℃, melting point 170℃, thermal decomposition temperature about 350℃, long-term use temperature -40 ~ 150℃. It can be formed by general thermoplastic processing methods. Its outstanding characteristics are high mechanical strength and good radiation resistance. It has good chemical stability, and is not corroded by acids, bases, strong oxidants and halogens at room temperature. Fuming sulfuric acid, strong alkali, ketone, ether sponge and a few chemicals can make it swell or partially dissolve, and strong polar organic solvents such as dimethyl acetamide and dimethyl sulphone can make it dissolve into colloidal solutions. The most common processes are emulsion polymerization and suspension polymerization.

Tensile strength

PVDF resin mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other copolymers containing a small amount of fluorinated vinyl monomer. PVDF resin has the characteristics of both fluorine resin and general resin, in addition to having good chemical corrosion resistance, high temperature resistance, oxidation resistance, weather resistance and radiation resistance. It also has special properties such as piezoelectricity, dielectric property and thermoelectricity, and is currently the second largest product in fluorinated plastics, with a global annual production capacity of more than 43,000 tons. PVDF applications are mainly concentrated in the petrochemical, electronic and electrical and fluorocarbon coatings three major fields, due to PVDF good chemical resistance, processing and fatigue and creep resistance, is one of the best materials for the petrochemical equipment fluid handling system as a whole or lining pumps, valves, pipelines, pipeline accessories, storage tanks and heat exchangers.

Its good chemical stability, electrical insulation performance, so that the production of equipment can meet the requirements of TOCS and flame retardant, is widely used in the semiconductor industry of high-purity chemicals storage and transportation, in recent years, the use of PVDF resin made of porous film, gel, diaphragm, etc., in the lithium secondary battery application. This is one of the fastest growing markets for PVDF. PVDF is one of the most important raw materials of fluorocarbon coatings, fluorocarbon coatings prepared with its raw materials have been developed to the sixth generation, because PVDF resin has superior weather resistance, can be used outdoors for a long time without maintenance, such coatings are widely used in power stations, airports, highways, high-rise buildings, etc. At present, there is no room temperature curing fluorocarbon resin for coatings with vinylidene fluoride as fluorine monomer and other fluorine monomer copolymerization in China, which has great development space. In addition, PVDF resin can also be blended with other resins, such as PVDF and ABS resin blended composite materials, has been widely used in construction, automotive decoration, home appliance shell and so on.
