Teflon & Ptfe

PTFE, or PolyTetraFluoroEthylene, refers to the polymer (CF2)n. This synthetic fluoropolymer of tetrafluoroethylene is hydrophobic, non-wetting, high-density, and heat-resistant, making it a highly versatile material. It is especially recognized for its non-stick characteristics.

PTFE is a high-performance engineering specialty polymer developed by Dr. Roy J. Plunkett at DuPont's Jackson Laboratory in New Jersey, USA, on April 6, 1938. This polymer exhibits remarkable characteristics, particularly in chemical inertness and heat resistance.

TFE Monomer is generally manufactured by synthesis of Calcium Fluoride (Fluorospar), Sulphuric Acid & Chloroform. The polymerisation of TFE is carried out in carefully controlled conditions to form PTFE. The chemical structure of PTFE is due to presence of stable & strong C-F bonds, PTFE molecule possess outstanding chemical inertness, high heat resistance & remarkable electrical insulation characteristics, in addition to excellent frictional properties

PTFE is a polymer widely utilized in the chemical, mechanical, and electronic industries:

• Chemical inertness to all known substances, although it is susceptible to attack by molten alkali metals, chlorine, trifluorides, and fluorine.
• Resistant to solvents, remaining insoluble in all solvents up to 260°C. Some highly fluorinated oils may cause swelling
• Operating temperature range from -25°C to 260°C, applicable at atmospheric pressure
• The metal with the least friction coefficient among all recognized metals.
• Nontoxic refers to substances that are safe and do not cause harm to living organisms or the environment.
• Resistance to radiation: the electrical properties stay nearly the same throughout.
• Outstanding resistance to weathering.
• Exceptional electrical and insulating characteristics across a broad frequency spectrum
