In recent years, there has been a lot of buzz around the polymer Polyvinylidene Fluoride (PVDF). It sparked interest because it has the strongest piezoelectric characteristics of any commercial polymer. Polymers are frequently employed in high-tech applications such as chemical process equipment, electrical and electronic equipment, speciality and energy-related applications. But what makes PVDF PIPE a high-performance plastic in a variety of industries? Continue reading to learn more.
PVDF (Polyvinylidene Fluoropolymer) is a strong, stable fluoropolymer with particular technical benefits. PVDF, which was discovered in 1969 by Dr. Heijji Kawai, offers an excellent performance-to-cost ratio.
PVDF is a semi-crystalline thermoplastic that is utilized in applications that need the utmost purity and can survive severe chemicals. PVDF is one of the most radiation-resistant polymers available, only being outperformed by PEEK and Polyimide.
The polarity of alternating CH2 and CH2 groups on the polymer chain leads to very desired insolubility and electrical characteristics.
When compared to other fluoropolymers, PVDF has a low density (1.78/cm3).
Our FL308 is available in Rod, Tube, and Sheet forms and may be manufactured via injection moulding, compression moulding, or hot moulding. This material is widely utilized in the semiconductor, defence, chemical, and medical sectors, as well as in the manufacture of lithium-ion batteries.
PVDF, which consists of homopolymers and copolymers, is
typically produced using the free radical polymerization of 1,1-difluoroethylene (CH2=CF2). Polymerization occurs in a suspension or emulsion at temperatures ranging from 10-150°C and pressures ranging from 10-300 atm. The resultant material is subsequently processed into film or sheets.
PVDF Fittings copolymers are most often prepared using chlorotrifluoroethylene (CTFE) or hexafluoropropene (HFP).
Copolymers are appropriate for wire and cable as well as tube applications that require increased flexibility.
Production of the PVDF Solef® lines is carried out according to the highest quality standards and in full compliance with the environmental restrictions set by the applicable laws in force and in accordance with ISO 14001. All products are made in accordance with the quality guarantee system in compliance with ISO 9001.
Polyvinylidene fluoride (PVDF) is a high weight fluoropolymer and long-lasting thermoplastic with good thermal, mechanical, electrical, and chemical properties. PVDF is exceptionally well suited for material engineering and plastic-type applications because of these qualities. For long-term service, Kynar PVDF is essentially inert, durable, and stable. PVDF, being a thermoplastic polymer, loses stiffness when heated, allowing for product recycling and reformation. Kynar, as synthetic plastic, is resistant to high temperatures, harsh/aggressive chemical handling, pressured fluid systems, and outdoor installations. PVDF products are permitted for usage at temperatures as high as 284°F prior to material softening. This is significantly higher than PVC or CPVC, which have maximum service temperatures of 140°F and 200°F, respectively. PVDF resins may be suitable for even higher temperatures, depending on the individual grade.
PVDF products like PVDF Ball Valve are naturally resistant to many of the problems associated with other materials. PVDF is resistant to surface abrasion, fungus, algae, and microbial film growth, the formation of fire and smoke, ozone exposure and usage damage, and is naturally unaffected by the breakdown effects of sunlight UV to which most other polymers are prone. PVDF is an excellent insulator that resists both hot/cold thermal transfer and electrical conductivity. PVDF also has unusual piezoelectric capabilities, which means it may respond to and influence electrical and/or magnetic fields.
PVDF PIPE rates high among synthetic and metallic materials in terms of chemical compatibility, as well as resistance to chemical penetration and attack. PVDF is chemically stable and resistant to strong acids, strong oxidants, solvents, halogens, alcohols, salts, and weak bases. PVDF has been observed to be possibly sensitive to softening and/or swelling when exposed to strong bases, esters, and ketone specified compounds.
It is important to know the right process of installation of PVDF. The processes differ for threaded and flanged joints.
For threaded joints:
To guarantee the hydraulic seal of the joint on fittings and valves with a threaded female end, we recommend you perform the following operations:
For flanged joints:
