Polyvinyl Chloride

Polyvinyl chloride is a thermoplastic polymer. It is a vinyl polymer constructed of repeating vinyl groups (ethenyls) having one hydrogen replaced by chloride. It is the third most widely produced plastic, after polyethylene and polypropylene. It is widely used in construction because it is cheap, durable, and easy to assemble. It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is used in clothing and upholstery, electrical cable insulation, inflatable products and many applications in which it replaces rubber.

Potassium Ferrocyanide

Potassium ferrocyanide is a coordination compound. It can be used as an alternate nitrogen source for plants. It is often used as a gardening technique. Industrially, this complex is used in metal extraction and to make adhesives, computer electronics, fire retardants, cosmetics, dyes, nylon, paints, inks, plexiglass, pharmaceuticals, and rocket propellant. It is also used in low doses in some food preparation. It works as an anti-caking agent and it removes copper from red wine, as copper is used as a fungicide on grapes. In the laboratory, potassium ferrocyanide is used to determine the concentration of potassium permanganate, a compound often used in titrations based on redoxreactions.

Rhenium Rod Industrial Grade 99.9%

Rhenium metal is silvery rod, bar, stick, plate, sheet, foil, strip, coil and powder. It exists in soot from calcinator for molybdenite and copper ore, which is byproduct of refining molybdenum and copper. Ammonium perrhenate (NH4ReO4) and potassium perrhenate(KReO4) are the raw materials.  Its chemical properties are close to manganese and technetium.

Rhenium Metal 

CAS No.:7440-15-5 EINECS No.: 231-124-5 Molecular Formula:Re Molecular Weight:186.207
Melting Point:3180℃ Boiling Point:5900℃ Density:21.04 UN 3178 4.1/PG 2

Applications

Rhenium metal bar is mainly for nickel-rhenium alloys, which apply to manufacturing combustor, turbine blade and exhaust nozzle of jet engine.  These alloys contains 6% rhenium at highest.

Rhenium can enhance physical property of tungsten. W-Re alloys have better plasticity at low temperature and high-temperature stability is better too, which is easy to process and shape. The change increase with the amount of rhenium increase, so W-Re alloy contains 27% rhenium, which is also the solublity limit of rhenium in tungsten. The alloys can apply to X-ray sources and thermocouple

In chemical industry, rhenium metal powder can use as catalyst for dehydrogenation.  Rhenium metal powder is raw material for Pt-Re catalys that is for producing gasoline without lead and high octane.  It is for spectral analysis too.
