PVDF pipe/tee elbow - xh026

PVDF tube/tee elbow - xh026 Product introduction PVDF tube/tee elbow - xh026 PVDF tube/tee elbow The appearance of PVDF tube/tee elbow is semi transparent or white powder or particles, with tightly arranged molecular chains and strong hydrogen bonds. The oxygen index is 46%, non combustible, crystallinity is 65%~78%, density is 1.77~1.80g/cm3, melting point is 172 ℃, thermal deformation temperature is 112~145 ℃, and long-term use temperature is -40~150 ℃

PVDF tube/tee elbow is a copolymer of a small amount of fluorine-containing vinyl monomers, which combines the characteristics of fluororesin and general-purpose resin. In addition to good chemical corrosion resistance, high temperature resistance, oxidation resistance, weather resistance, and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and thermoelectric properties. It is the second largest product in fluorine-containing plastics production, with a global annual production capacity of over 53000 tons.

In the chemical structure of PVDF pipes/three-way elbows, fluorine carbon bonding is used, which forms the most stable and firm bond with hydrogen ions due to its short bond properties. Therefore, fluorocarbon coatings have specific physical and chemical properties, not only strong wear resistance and impact resistance, but also high resistance to fading and ultraviolet radiation in extremely harsh and harsh environments.

PVDF pipe/tee elbow is a coating made of PVDF meltable fluorocarbon resin, which is homopolymerized from vinylidene fluoride (VDF) with a purity of ≥ 99.99%. The fluorocarbon coating made of 70% PVDF resin has unparalleled super weather resistance and processing performance when sprayed or roller coated and baked into a paint film. Fully comply with the American Building Materials Standard AAMA2605 and the Chinese Industry Standard HG/T3793-2005. PVDF not only has strong wear resistance and impact resistance, but also has high resistance to fading and ultraviolet radiation in extremely harsh and harsh environments. PVDF is the second largest production of fluoroplastics, with a global annual production capacity of over 53000 tons.

PVDF (polyvinylidene fluoride) has the strongest toughness, low friction coefficient, strong corrosion resistance, aging resistance, weather resistance, and good radiation resistance among fluoroplastics.

Application scope of PVDF pipe/tee elbow

PVDF applications are mainly concentrated in three major fields: petrochemicals, electronics and electrical, and fluorocarbon coatings. Due to its excellent chemical resistance, processability, fatigue resistance, and creep resistance, PVDF is one of the best materials for pumps, valves, pipelines, pipeline fittings, storage tanks, and heat exchangers in petrochemical equipment fluid treatment systems as a whole or lining. PVDF has good chemical stability and electrical insulation performance, so that the equipment can meet the requirements of TOCS and flame retardancy. It is widely used in the storage and transportation of high-purity chemicals in the semiconductor industry. Porous membranes, gel, separators, etc. made of PVDF resin are used in lithium secondary batteries. At present, this use has become one of the fastest growing markets for PVDF demand. PVDF is one of the main raw materials for fluorocarbon coatings, and fluorocarbon coatings prepared from it have developed to the sixth generation. Due to its strong weather resistance, PVDF resin can be used outdoors for a long time without maintenance. This type of coating is widely used in power plants, airports, highways, high-rise buildings, etc. In addition, PVDF resin can also be modified by blending with other resins, such as PVDF and ABS resin to obtain composite materials, which have been widely used in construction, automotive decoration, household appliance shells, etc.
