Polyvinylidene Fluoride / PVDF Rods
Polyvinylidene Fluoride / PVDF Rods
Polyvinylidene fluoride / pvdf is one of the world’s toughest high purity synthetic materials with exceptional chemical resistance, strength and thermal stability.polyvinylidene fluoride / pvdf rods It is available as sheet, rod, film and tubing in a wide range of sizes for numerous applications. Its superior performance makes it a desirable choice for industries that require low permeability to chemicals, mechanical stress, or pressure and temperature extremes.
PVDF is a semi-crystalline polymer composed of long chains of repeating units linked together through a human-derived synthesis reaction.polyvinylidene fluoride / pvdf rods Unlike many other plastics, it does not require stabilizers, plasticizers or lubricants. Its pure, chemically inert structure also translates into a stable material that is easy to machine, extrude or fabricate. Its excellent anti-adhesion and abrasion properties combined with an exceptionally broad operating temperature range and low water absorption make it an ideal material for chemical processing, harsh/aggressive chemical handling, pressurized fluid systems and outdoor installations.
It can be fabricated into solid shapes, film and tubing by melt casting, extrusion, spinning and Langmuir-Blodgett processes.polyvinylidene fluoride / pvdf rods It can also be processed from a solution, typically with the addition of the solvent perfluorononanoic acid. PVDF can be made into a variety of finishes including glass reinforced, matt, glossy and self-lubricating.
The main reason for its enduring popularity in the industrial market is its outstanding chemical resistance and thermal stability. It is a very strong material with a modulus and tensile strength that is higher than most other thermoplastics. It is also extremely durable and has good impact resistance even at very low temperatures.
Like other fluoropolymers, PVDF has a very low chemical absorption rate. This property, coupled with its natural flame retardancy and ultrahigh purity, gives it excellent environmental safety characteristics. It is very resistant to many types of acids, bases and solvents, with good resistance to chemical permeation and attack.
Due to its outstanding mechanical and electrical properties, PVDF is commonly used in manufacturing equipment such as semiconductor manufacturing clean room components. It is also a popular material for tubing and piping, where its chemical resistance, mechanical strength, thermal stability and magno-electric properties make it ideal for corrosive environments.
PVDF is also a very good insulator, with a dielectric constant of over 100 million volts at 10 megahertz (MHz). It has a low boiling and melting point and can be used for a wide temperature range of -195°C to +270°C.
In the petrochemical industry, PVDF is a top-choice for pumps, valves, tanks and heat exchangers in liquid handling systems. It can handle a wide range of chemicals and withstand high pressures, mechanical stress, aggressive chemicals and abrasive particles. It also performs well in harsh environmental conditions and resists degradation from the effects of UV, radiation and aging.
