 Only Plastpolymer Joint Stock Company produces TPFP films in Russia. Melting fluoropolymer films have a complex of unique properties and retain all advantages of film materials, the basic one of them is high efficiency at low consumption of materials. Films retain excellent properties of initial polymers, namely tensile strength, multiple bend stability, extreme temperature stability, radiation stability, stability to corrosive fluids, transparency. Properties of films depend upon the initial polymer and processing conditions. As a rule, fluoropolymeric films are produced by flat die extrusion and winding onto drum with specific temperature. Depending upon the application films can be produced with various widths up to 450 mm and thickness from 0.010 to 0.50 mm. TPFP films are used to produce combined film materials with the complex of properties that can not be provided by a single polymer in its pure form. These films are not explosive, hardly inflammable, they do not effect upon people in case of direct contact at 25±10 оС. When fluoroplastic films are produced any pollution protection is not required. Basic Properties of Thermoplastic Fluoropolymeric Films.
