Teflon was discovered by Roy J. Plunkett (1910-1994) in 1938 and was used as a commercial product in 1946.Scientifically teflon is called polytetrafluroethylene (PTFE). This is a polymer which has repeating chains of –(CF
2-CF
2)- in it.
1. In electronics industry it is used on account of its insulation property in wires and system components.Also used because of its outstanding electrical performance and durability.
Uses for coating
2. Used for metal finishing, paints and coatings,as flour additives can be added to reduce the wear and tear on load-bearing surfaces. For example in inks and lithographic printing, thermoplastics and molded gears, protective industrial surfaces, lubricants to thicken, sterile packaging, etc.
Uses as automobile air bags
3. In optical devices, as it can be used as clear coating, requiring a low refractive index and still perform in aggressive chemical environments over a wide range of use temperatures and light waves (UV-IR). For example, it is found in lightweight surgical lamps, photovoltaic cell glazing, etc.
4. In automobiles it finds its uses as airbag systems, fuel hose permeation barrier, fuel system, chassis, brake systems, oil filter, etc.
5. Used as nonstick coating on cooking
devices like pans, oven , tawa as it is nonstick and exceptional performance at high temperatures.
