TFE\/PDD is characterised by transparency and a small refraction index. Like the most others fluoropolymers, TFE\/PDD is resistant to multiplicity of chemicals and applicable over a wide temperature range. The service temperature of the copolymer lies under 360\u00b0C. At temperatures above 360\u00b0C the thermal decomposition of the copolymer starts. TFE\/PDD shows a exceptional resistance to UV-radiation and it is in a great extent permeable for UV-radiation.<\/p>\n<hr>\n<h2>Usage:<\/h2>\n<ul>\n<li>as optical fibre<\/li>\n<li>as coverage for lenses in the microwave- radar- and optical domain<\/li>\n<li>in UV cells<\/li>\n<li>as passivation and protective envelope<\/li>\n<li>as non-reflecting coat for optical units<\/li>\n<li>as highly permeable membrane for the separation of gases<\/li>\n<\/ul>\n<hr>\n<h2>Formula:<\/h2>\n<p><img fetchpriority=\"high\" decoding=\"async\" src=\"\/wp-content\/uploads\/TFE_PDD.jpg\" alt=\"Tetrafluoroethylene-Perfluorodimethyldioxole- Fluorocopolymer (TFE\/PDD)\" width=\"400\" height=\"269\"><\/p>\n<blockquote><p>Category:<br \/>Thermoplastic<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Description: TFE\/PDD is a thermoplastic, amorphous fluorocopolymer, which is also known under the name TEFLON\u00aeAF by DuPont.
