Depending on the application temperature, media and concentration, a number of fluoropolymers are available. +31 (0)76 - 5718295 This makes PTFE harder to burn and more heat resistant than ETFE. Click to see.

Working as a hydrophobic, neither water nor water-based substances wet PTFE. It has a slightly higher coefficient of friction, lower continuous service temperature, and is more transparent than PTFE. ETFE is distinguished from perfluopolymers (totally fluorinated polymers) as a partially fluorinated copolymer of ethylene and TFE. Chemical Resistance - Zeus fluoropolymers and other engineered products are ideal as transport for today's highly volatile chemical compounds and exotic fluids. Materials of Construction. FEP also has better gas and vapor permeability properties and excellent UV transmission. Both PTFE and PFA show outstanding chemical properties for resistance to corrosive agents, non-solubility, and non-flammability. These can be used as structural materials or as corrosion protection lining. sf: (650) 871-6566 l benicia (707) 746-1600 so. PTFE Chemical Resistance Chart. Click to see. PTFE (or polytetrafluroethylene) is a fluorocarbon solid. ETFE, or ethylene tetrafluoroethylene, consists of carbon, fluorine and hydrogen, has a higher tensile strength than PTFE, though PTFE will stretch before breaking. ETFE Properties. Shop for ETFE .

Tech Tip– ETFE is stiffer and has better creep resistance than many softer fluoropolymers such as PTFE or FEP. This chemical modification provides significantly higher strength relative to PTFE, FEP or PFA.

Fluoropolymers (PVDF, ECTFE, FEP, and PFA) Highest corrosion resistance in the plastics sector. Both are virtually identical in terms of their electrical properties for dielectric, dissipation, and surface resistivity.

CHEMISTry COMPATIBIlITy Inlet and outlet flapper valves are made of FFKM or PTFE for both highest leakage tightness and best chemical resistance FFKM Valve connectors are made of ECTFE for an optimum of thermal, mechanical and chemical resistance ECTFE Head cover and clamping disc are made of thick walled molded ETFE with

Chart Codes.

Note: The chemical resistance of each polymer is mainly determined by the chemical structure of the material and the strength of the weakest link in this specific structure. While similar to PTFE, FEP has some distinct differences. ETFE has a lower working temperature of up to 150°C, whereas PTFE has a higher working temperature of up to 230°C. PTFE is far harder to burn, as it requires a higher concentration of ambient oxygen. It is also more heat resistant, melting at 327°C, which is 60°C more than ETFE. 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.
