POLYTETRAFLUOROETHYLENE - PTFE Developed in 1938, PTFE become widely known with the name TEFLON from Dupont. Because water and water containing substances like most foods do not wet PTFE, adhesion to PTFE surfaces is inhibited. Owing to this property, PTPE is used as a non-stick coating for pans and other cookware. It is very non-reactive and therefore it is often used in containers and tubes for reactive and corrosive chemicals. Wher used as a lubricant, PTFE reduces friction, wear and energy consumption of machinery. Main properties of PTFE are as follows:
• High resistance to high temperatures (+260°C)
• Low coefficient of friction
• Suitable for contact with food
• Excellent resistance to chemicals and hydrolysis
PTFE (PolyTetraFluoroEthylene)
*The strength of the carbon-fluorine bond and the high atomic weight gives PTFE a range of outstanding properties.
*High Heat Resistance: The high heat resistance allows PTFE products to be used in continuous service without losing their physical properties in high heat applications up to + 260°C (500°F), and in low heat applications down to - 70°C (-95°F).
*Excellent resistance to corrosives and chemicals
*Self lubricating and anti-sticking
*Outstanding electric properties. PTFE has high dielectric strength, low loss factor, and very high surface resistance on a broad frequency range.
*PTFE can be manufactured as an electric conductor for anti-static applications using special techniques.
*Good mechanical properties. Excellent tensile strength in low and high temperatures conditions, good resistance to fatigue and impacts.
*Total resistance to ageing, humidity and UV rays.
*Nontoxic and qualified for use in food industry.
Fields of Application:
*Chemistry
*High temperature applications
*Food and beverages
*Medical devices
*Laboratory
*Equipment
*Electrical insulation
*Paint, Coating
*Medicine
*Automotive
*Motorcycle
FEP (Fluorinated Ethylene Propylene)
*FEP is a solution that can be processed as a fluorinated plastic.
*FEP has similar properties as those of PTFE, but has some specific differences. Its coefficient of friction is slightly higher.
*Wide continuous operating temperature range: up to 205 °C (400°F) and down to -60°C (-75°F).
*High clarity and excellent UV resistance.
*Low gas and vapor permeability.
Fields of Application
*UV applications
*Chemistry
*Food and beverages
*Medical devices
*Laboratory
*Medicine
*Equipment
*Gas sampling
*Flow monitoring
PFA (Perfluoroalkoxy)
*PFA is a solution that can be processed as a wholly fluorinated, high-purity high-quality fluorinated plastic.
*PFA is the best combination of the properties offered by PTFE and FEP.
*Wide operating temperature range: up to 260 °C (500°F) and down to -70°C (-95°F).
*Low coefficient of friction, and anti-sticking properties
*Excellent resistance to corrosives and chemicals.
*High clarity and excellent UV resistance.
*Longer flexibility life.
*Low gas and vapor impermeability.

*UV applications
*Chemistry
*Food and beverages
*Medical devices
*Laboratory
*Medicine
*Equipment
*Gas and air sampling
*Flow monitoring
*Semi-conductive wet benches
