PTFE Tube has fantastic resistance to almost all chemicals, and is virtually inert. ... PTFE. It is stable in most aggressive and corrosive media, exceptions being liquid or dissolved alkali metals, flourine and other extremely potent oxidisers. PTFE Chemical Compatibility Chart A Suitable B Consult with TEADIT C Not recommended PRODUCT TF1570 TF1580 TF1590 Teadit 24SH Teadit 24B TF 1510 Chlorine Trifluoride C C C C C Chlorine, Dry or Wet A A A A A Chloroacetic Acid A A A A A 2-Chloroacetophenone A … It is stable in most aggressive and corrosive media, exceptions being liquid or dissolved alkali metals, flourine and other extremely potent oxidisers. Santoprene Chemical Resistance: Santoprene is a thermoplastic rubber designed to offer chemical resistance equivalent to neoprene.
PTFE Chemical Resistance This chart is intended to be used as a general guide only. B = Slight attack by absorption. PTFE hose offers exceptional chemical resistance, operates up to 500°F/260°C and handles pressures as high as 5,500 psi. Ductile iron flanges with tapped bolt holes, integral steel limit bolts, and reinforcing rings enable them to absorb vibration and allows thermal movement and misalignment in piping. As discussed above, PTFE has excellent properties such as chemical inertness, heat resistance (both high and low), electrical insulation properties, low coefficient of friction (static 0.08 and dynamic 0.01), and nonstick property over a wide temperature range (260 to 260°C). Material PTFE = Polytetrafluoroethylene including of Teflon® SS = Stainless Steel (316) PE#1 = Convenional Polyethylene PE#2 = Rigid Polyethylene PP = Polypropylene PVC = Polyvinylchloride Algoflon® PTFE is a high-molecular-weight thermoplastic consisting wholly of carbon and fluorine atoms.
It is resistant to a wide variety of solvents and chemicals. Since each rating is for ideal conditions, all factors affecting chemical resistance must be considered. Chemical Resistance Chart; Legend. PTFE is a soft fluoropolymer mechanical plastic with exceptional resistance to high temperatures, chemicals, corrosion and stress cracking. PTFE extruded tubing, and PTFE shrink tubing, are used … Chemical resistance PTFE. Skived sheets are more likely to curl than molded sheets. PTFE Chemical Resistance Chart. However, since the resistance of metals, plastics and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors. Many factors can affect the chemical resistance of a given plastic product, and it is your responsibility to do a test under your own conditions to ensure that the product you are using is fully compatible with your usage.
PTFE is stable at temperatures up to 500 o F and it is often used in high temperature environments . It … Chemical Resistance of Virgin PTFE: The chemical resistance of Virgin PTFE is excellent. These high temperature hoses are available with a smoothbore or convoluted moisture resistant core tube in a natural or conductive hose design. Pipe Gasket Chemical Resistance. PTFE expansion joints combine chemical resistance and our shortest face-to-face. Chemical Structure of PTFE Polytetrafluoroethylene Poly Tetra Fluoro Ethylene is a linear polymer free from any significant branching have chemical structure as: In PTFE, due to large fluorine Atom, PTFE Molecule takes up a twisted zigzag, with the fluorine atoms packing tightly in a … A = No Attack, possibly slight absorption. Acetaldehyde E Bromi ne * Cresol E Acetamide, Sat. It is not readily soluble in common solvents but will swell in aromatic solvents and halogenated organic solvents. Chemical Resistance of Virgin PTFE The chemical resistance of Virgin PTFE is excellent.
Some organic and halogenated solvents are absorbed causing minor dimensional changes but these effects are physical and also reversible. Some swelling and a small reduction in mechanical likely. The information is based primarily on the immersion of unstressed strips in the chemicals at ambient temperature and, to a lesser degree, on field experience.
It is easy to machine and is an excellent electrical insulator. Resistance E = Excellent G = Good F = Fair N = Not Recommended . The Chemical Resistance table below outlines many of the chemicals our PTFE Tubing can be used with, and it's resistance to them. Chemical Resistance of Virgin PTFE The chemical resistance of Virgin PTFE is excellent. Negligible effect on mechanical properties. PTFE surpasses most plastic when it comes to chemical resistance and performance in extreme temperatures. PTFE is not chemically resistive to.
