| Polyvinylidene fluoride, or PVDF, is a fluorinated thermoplastic resin which has outstanding resistance to most mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols, halogenated solvents, and oxidizing environments. It also has outstanding aging resistance, with its properties remaining constant after many years. TECAFLON® PVDF’s excellent chemical and physical properties and the ease with which it can be processed make it especially suitable for components in the chemical, petrochemical, hydrometallurgical, pharmaceutical, food, nuclear, and paper and pulp industries, as well as the semiconductor processing industry. Superior chemical resistance Remarkable fire resistant properties UV and gamma radiation stability Very high dielectric and piezoelectric constants Absolutely non-toxic Good mechanical properties in tension as well as in deflection, torsion, and compression compared to other fluorinated polymers Does not swell or alter in a wet environment Uses standard machining and welding techniques&& |
