TefzelTM Fluoropolymer Resin Chemical Use Temperature Guide Technical Information TefzelTM--Tough for Abrasive Service TefzelTM fluoropolymer resin is a proven performer in the chemical and petrochemical processing industries. It has gained notable recognition for its unique properties and design versatility that are helping to solve some of the industry's toughest materials problems in process equipment and components. Like the Chemours family of TeflonTM fluoropolymer resins, TefzelTM provides excellent resistance to attack by chemicals and solvents that can cause rapid deterioration of other plastics and all but the most costly metal alloys. TefzelTM is inert to strong mineral acids, inorganic bases, halogens, and metal salt solutions. Even carboxylic acids, anhydrides, aromatic and aliphatic hydrocarbons, alcohols, aldehydes, ketones, ethers, esters, chlorocarbons, and classic polymer solvents have little effect on TefzelTM. Very strong oxidizing acids near their boiling points, such as nitric at high concentration, will however affect TefzelTM in varying degrees. So will strong organic bases, such as amines and sulfonic acids. In addition to its chemical resistance, TefzelTM has excellent mechanical strength, stiffness, and abrasion resistance. This may be an important consideration for process applications where abrasive slurries often accelerate wear and degradation of alternative materials. TefzelTM can also be reinforced with glass fibers to increase the flexural modulus to 950,000 psi/6,550 MPa. TefzelTM has a broad continuous use temperature range from -150 to 300 F (-100 to 150 C). Specific temperature ratings vary with equipment design; thus, it is important to consult with component manufacturers for in-use service recommendations. Chemical Resistance Guide Table 1 lists over 450 chemicals whose corrosive characteristics create problems that can often be solved by specifying TefzelTM fluoropolymer. The maximum use temperature for each chemical service listed is suggested as a guide only. Not all chemicals listed have been tested in a Chemours laboratory. This guide is based on selective laboratory tests of representative chemicals; field applications and experience; and engineering judgments as to the suitability of TefzelTM in these chemical environments. Table 1 lists chemicals and the "upper suggested use temperatures" for organic and inorganic chemicals and plating solutions. The temperature ratings, especially for inorganic chemicals, apply to aqueous and non-aqueous systems. It is recommended that tests be conducted under actual or simulated use conditions wherever possible to determine suitability of TefzelTM or any other material for a specific application. It is also suggested that the equipment fabricator be consulted for in-use service recommendations. Representative Compatibility Data The data presented in Table 2 show the effects of various representative chemicals on the properties of TefzelTM as tested in Chemours laboratories. The test results shown in Table 2 represent the tensile strength, elongation, and weight changes after exposures at indicated temperatures. These test results confirm the chemical-resistant properties of TefzelTM. TefzelTM Fluoropolymer Resin Table 1.
