What material is PVDF?

November 09,2022

PVDF resin refers to homopolymer of vinylidene fluoride or copolymer of vinylidene fluoride and a small amount of other vinyl monomers containing fluorine. PVDF resin has the characteristics of fluorine resin and general resin. In addition to good chemical resistance and corrosion resistance, it also has special properties such as high temperature resistance, oxidation resistance, weather resistance, radiation resistance, etc., such as piezoelectric, dielectric, and thermoelectric properties. It is the second largest product of fluoroplastics at present.

PVDF application

It is mainly concentrated in petrochemical industry, electronic and electrical industry and fluorocarbon coatings. Because PVDF has good chemical resistance, processability, fatigue resistance and creep resistance, it is an integral or lined pump, valve and pipeline of petrochemical equipment fluid treatment system., One of the best materials for pipe fittings, tanks and heat exchangers. Its good chemical stability and electrical insulation enable the production equipment to meet the TOCS and flame retardant requirements. It is widely used in the storage and transportation of high purity chemicals in the semiconductor industry. In recent years, porous membranes and coagulants made of PVDF resin have been used. Adhesives, separators, etc. are used for lithium secondary batteries. At present, this application has become one of the fastest growing markets for PVDF. PVDF is one of the most important raw materials for fluorocarbon coatings. The fluorocarbon coating prepared from it has developed to the sixth generation. Because PVDF resin has excellent weather resistance, it can be used outdoors for a long time without maintenance. This kind of coating is widely used in power stations, airports, highways, high-rise buildings, etc. In addition, PVDF resin can also be modified by blending with other resins. For example, PVDF and ABS resin can be blended to obtain composite materials, which have been widely used in the fields of architecture, automobile decoration, home appliance shell, etc. The chemical structure is combined with fluorocarbon bond. This short bond structure forms the most stable and firm bond with hydrogen ions. Therefore, fluorocarbon coatings have specific physical and chemical properties, which not only have strong wear resistance and impact resistance, but also have high fade resistance and UV resistance in harsh and harsh environments.

We currently mainly sell thermoplastic elastomers

(SBS,SEBS,SIS,SEPS,SSBR) and plastic chemical products such as polypropylene (PP drawing, injection molding, copolymerization), polyethylene (LDPE, HDPE, LLDPE).
