ETFE Chemours/Dupont Tefzel and Solvay Haylar ECTFE
Chemours/Dupont Tefzel ETFE fluoropolymer and Solvay Haylar ECTFE are proven performers in the chemical and petrochemical processing industries. Their unique combination of properties and design versatility are helping to solve some of the toughest materials problems in process equipment and components.
What is HAYLAR ECTFE material?
Solvay Haylar ECTFE is a partially fluorinated semi-crystaline polymer offering a unique combination of mechanical properties, thermal and chemical resistance with outstanding ease of processability. Haylar ECTFE is a copolymer of ethylene and chlorotrifluoroethylene can bring advantages to the end user when compared to other fluoropolymers. It is a very versatile polymer available in all forms to meet processing needs Haylar Sheet offers excellent resistance to abrasion, harsh chemicals, and permeation.
What is TEFZEL ETFE Material?
Chemours/Dupont ETFE TEFZEL is a modified copolymer of ethylene and tetrafluoroethylene that is often used in applications that demand mechanical toughness with thermal, mechanical and chemical extremes. Tefzel ETFE material provides excellent resistance to attack by chemicals and solvents which can cause rapid deterioration of other plastics and all but the most costly metal alloys. Tefzel and Haylar ECTFE materials are 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 ETFE Tefzel Plastic. However, very strong oxidizing acids, such as highly concentrated nitric acid, will affect Tefzel ETFE and Haylar ECTFE in varying degrees. Organic bases such as amines and sulfonic acids will also affect Tefzel ETFE materials.
ETFE Tefzel sheet also 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. Tefzel ETFE plastic can also be reinforced with glass fibers to increase the flexural modulus to 95,000 psi.
Tefzel ETFE material has a broad continuous use temperature range from -370 degrees F/-223 degrees C to +300 degrees F/+150 degrees C.
