polypropylene pfa vs nitrile tube

Teflon (FEP) Labware | Thermo Fisher Scientific - US

FEP is most frequently used to make products used in critical appliions where their inert properties and low extractables are valued, such as leak-proof Nalgene bottles and centrifuge tubes. FEP is also used where plastic is preferred over glass for its shatterproof properties, where the labware will be exposed to aggressive chemicals or extreme temperatures.

Teflon Vs PTFE What Really Are The Differences?

Teflon is a synthetic polymer containing carbon and fluorine called polytetrafluoroethylene. That’s right, Teflon is PTFE but by another name. Teflon is the trademarked brand name for PTFE owned by Chemours, and just as we call our vacuums Hoovers and sticky tape Sellotape, so we’ve come to know PTFE by the name it was given.

FEP / PFA / Teftek Chemical Compatibility

PFA and Teftek® also can be used under the appellation. Though all of the fluoropolymers can be alogued in the same family, they vary in regards to thermal and mechanical properties. PTFE and PFA have a raised temperature tolerance in comparison to FEP and Teftek®. FEP, PFA and Teftek® are clear, yet PTFE is translucent.

Rubber Tubing

Made from Nitrile rubber. This material strikes a good balance between cost and quality. EPDM foam tubing is available for high UV outdoor use. All of our foam tubing is latex free. Foam tubes are available cut to length or by the foot. Many sizes are available in coils which average 350 feet per carton.

FEP Tubing (Fluorinated Ethylene Propylene) - NMR Tubes

1-828-584-2600. FEP Tubing (Fluorinated Ethylene Propylene) is the preferred material in production of small diameter tubing of continuous lengths. While some temperature resistance is saced with FEP (to 400º F), its chemical and dielectric properties are similar to those of PTFE. FEP tubing is a clear tubing that is an economical choice

Yureka Sdn Bhd continuously diversify its business to seals and gaskets, provided material such as PTFE, Viton, EPDM, NBR, Neoprene, TPE, Engineering Plastics etc, covering the whole Malaysia with offices in Kuala Lumpur, Penang and Johor.

Difference Between PFA and PTFE | Difference Between

14/1/2012· PFA is more expensive and more rare than PTFE. I use a lot of PFA fittings and PFA tubing for handling corrosive liquids such sulfuric acid 93%. All my suppliers always give me extremely long delays because PFA is very expensive and rare so manufacturers produce parts in very low quantity. To give you an idea, a simple PFA 1” NPT cost about $40/ea.

Fluorinated Ethylene Propylene - an overview

Fluorinated Ethylene Propylene (FEP) FEP is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP), first produced by DuPont in 1956 (Teflon™ FEP) to reduce PTFE’s high crystallinity and melt viscosity. This improves FEP processing characteristics while maintaining high perfluorination. Bulky FEP perfluoromethyl groups

HDPE and PP Plastic: What''s the Difference? - Acme Plastics

7/1/2019· PP, which stands for polypropylene plastic, is a type of plastic that is specifically known for its semi-crystalline nature, it can be shaped and formed easy thanks to the material’s low-melt viscosity. Polypropylene is ideal for injection molding–but that isn’t its only use. Polypropylene plastic can be found in everything from ropes to



Polypropylene Copolymer - PPC | Emco Industrial Plastics

Polypropylene Homopolymer (PPH) is the most widely utilized. PPH offers a high strength to weight ratio and is stiffer and stronger than copolymer, this coined with good chemical resistance and weldability allows this material to be used in many corrosion resistant structures. Polypropylene copolymer (PPC) is a bit softer but have better

Southeastern Industrial Plastics : Polypropylene and PVDF

PP. (Polypropylene) PP as specified by ASTM D 4101, is a meer of the polyolefin family of pure hydrocarbon plastics. Although PP has half the strength of PVC and CPVC, with a design stress of 1,000 psi at 73° F, it may have the most versatile chemical resistance of the thermoplastic materials identified as the sentinels of industrial piping.

Perfluoroalkoxy alkane - Wikipedia

Compared to PTFE, PFA has better anti-stick properties and higher chemical resistance, at the expense of lesser scratch resistance. Unlike with PTFE, the alkoxy substituents allow the polymer to be melt-processed. On a molecular level, PFA polymers have a smaller chain length and higher chain entanglement than other fluoropolymers. They also contain an oxygen atom at the branches.
