Altafluor 100 PTFE was the original TEFLON material developed by E.I.DUPONT CO. PTFE is the most flexiible of all fluoropolymers offered. It has the broadest temperature range of any fluoropolymer and can resist highly corrosive liquids and gases even at elevated temperatures. The smooth surface finish and lowest coefficient of friction and lubricity make it ideal for bushing or bearing applications. Non-flammable. Non-toxic. FDA compliant -21 CFR 177.1550. Very low permeability. Altafluor 100 is compatible with most standard fittings (not suitable for use with flare-type fittings). Applications include use in laboratories, chemical processes, analytical and process equipment, crogenic, electrical, high temp and automotive. Manufactured from 100% virgin grade PTFE resins, it is the most flexible, is chemically inert and resistant to nearly all industrial chemicals and solvents.
