Polyvinalidene Fluoride: PVDF is a specialty plastic material in the fluoropolymer family; it is used generally in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. Compared to other fluoropolymers, it has an easier melt process because of its relatively low melting point of around 177°C.

What is pvdf and pfa and what is the history of both the material?
PVDF, also known as poly(vinylidene difluoride), is a man-made polymer of 1,1-difluoroethylene. It's most commonly used as an insulative coat for electrical cables, but because of it's diversity as a material is also widely used in the Aerospace, Chemical, Construction, Military, Fishing, Medical and Semiconducting industries in various forms including those such as coatings, piping, tubing, sheets, films, plates, foams and insulators. PVDF has a high electrical resistivity, with a volumetric resistivity of 200,280 ohms per cubic metre, and a surface resistance of approximately 500,700 ohms per square metre, making it an ideal insulator and useful for coating fishing lines and wires. PVdF can also be made into a membrane form used to immobilize proteins, and is a highly flexible and tensile material, with a good chemical and solvent resistance. As far as specific dates go, I couldn't tell you much else about PVDF from my knowledge of the material, and, unless by PFA you mean Paraformaldehyde, I couldn't tell you anything about that either, sorry. I hope the information I have been able to provide helped, though!

Character of a Western blot?
Western blotting is a technique to detect specific proteins from a sample such as cell or tissue lysates. Western blot is a membrane (nitrocellulose or PVDF) on which the proteins are transferred for further analysis. Proteins on the blot are visualized by specific antibodies.

What is epdm ptfe stress saver gaskets?
EPDM/PTFE STRESS SAVER GASKETS T10(equivalent to Asahi gasket)----www.rubbersealing.comT.C.I valve gaskets offer a unique double convex ring design that gives optimum sealing with only one third the torque commonly required with flat faced gaskets. Asahi offers EPDM gaskets from 1/2" to 12"; PTFE-bonded EPDM gaskets in sizes from 1/2" to 12"; and PVDF-bonded EPDM gaskets from 1/2" to 10".Features and BenefitsEPDM - durometer A, hardness 65 - 68PTFE or PVDF-bonded EPDM for maximum corrosion resistancePerfect sealing at low bolt tightening torque ratings; longer gasket lifeIdeal for plastic piping systems, as well as metal or plastic-lined metal systemsWorking temperature:EPDM: - 40 - 195º FPTFE-bonded: - 40 - 250º FPVDF-bonded: - 40 - 250º FApproximately one third bolt tightening torque ratings as compared with flat or envelope type gasketThickness of bonded materialsPTFE: All Sizes: 0.016" (0.4mm)PVDF:Sizes 1/2" - 2": 0.016" (0.4mm)PVDF:Sizes 3" - 10": 0.020" (0.5mm)PTFE-bonded gasket excellent for most corrosive chemicalsPVDF-bonded gasket is ideal for the following:Semi-conductor industry, because of its purityAggressive chemicals (strong acids, bases, halogens, etc.)Media that generates any volatile gas (PVDF gas permeation is only 1/50 of PTFE)Both the PTFE and PVDF-bonded gaskets employ a proprietary laminating process for bonding to EPDM, providing the greater elasticity required for lower sealing torquesMaterialsSizes:EPDM: 1/2" - 12"PTFE-bonded EPDM: 1/2" - 12"PVDF-bonded EPDM: 1/2" - 10" (except 1 1/4" and 2 1/2")Typical ApplicationsChemical ProcessingWater & WastewaterLandfillsIrrigationFood ProcessingMining
