Plastic Shilp Udyog

P. T. F. E. ( Poly Tetra Fluoro Ethylene ) Is a highly versatile product with remarkable properties viz. Self lubricating, nonstick, nontoxic, non wettable, non flammable, non brittle, extra low coefficient of friction and resistant to wide range of chemicals combines with excellent electrical properties and working temperature range from -250oc to + 260oc. Therefore, it is best suited material for bushes seal for revolving shaft application under the most corrosive acid, alkalis or solvent. P. T. F. E. Is well known material for exceptional properties with regards to chemical inertness, heat resistance & frictional properties, which lead to use of this material in very critical applications also. P. T. F. E. Can easily bended with various fillers like glass, graphite, carbon, bronze, mos2, and others to give the unique combination of the properties of p. T. F. E. And the advantageous characteristics of the blended fillers to suit for typical applications.
