Fluon® PTFE possesses numerous excellent properties and is widely used around the world. It is known as a highly functional fluoropolymer with superior characteristics,such as chemical resistance and heat resistance, as well as electrical insulation, low friction and non-stick properties.
●Heat resistance : Usable within a wide temperature range from -180 to +260ºC.
●Chemical resistance : Durable to the most of chemical agents and solvents.
●Nonflammability : Has an oxygen index of at least 95%, meets UL spcification UL94V-0, and is non - flammable.
●Electrical properties : Dielectric constant and dielectric tangent are stably low at all frequencies; exhibits excellent insulation.
●Friction : Shows the minimum coefficient of friction in solids.
●Non-stick : Excellent non-stick and release properties.
●Weather resistance : Can be used outdoors for a long period of time and is highly durable against sunlight, wind,rain and exhaust gases.
