PTFE / Teflon Coating
PTFE / Teflon Coating
PTFE / Teflon Coating and it’s variants have become a solution to many problems associated with modern manufacturing and materials handling, such areas benefiting from the material are; food processing and packaging, chemical protection and as a dry lubricant in place of oils. Other specialist chemical companies have expanded the technology and developed the business, thus offering almost unlimited opportunities within the range of PTFE / Teflon coatings. PTFE coatings, Teflon® and Xylan® have gained reputations for their non-stick properties, however, in modern day life the material has been put to many other uses, including uses in aviation, electronics, telecommunications, automobiles and trucks, as well as pollution control and renewable energy projects.
PTFE / Teflon Coating is extraordinarily resistant to chemical attack, and the surface free energy of solid PTFE / Teflon Coating is very low. This means that liquids do not readily wet the solid, and other solids do not adhere strongly. These properties render PTFE / Teflon Coating very valuable for forming protective surface coatings, in a wide range of applications from non-stick cookware to surgical sutures. However, the very properties which make PTFE / Teflon Coating so useful in such applications also make it very difficult to form PTFE / Teflon Coatings which are sufficiently adherent to their substrates.
Industrial coatings are aqueous based and are milky white dispersions of PTFE / Teflon Coating particles in water, stabilized by wetting agents. They can be further formulated to meet specific needs by adding other solid or liquid ingredients and pigments. These aqueous dispersions offer a practical method for coating or impregnating using a resin that does not respond to traditional solvent or melt-processing techniques.
Using new polymer technology and a cleaner, more effective new wetting agent, current PTFE / Teflon Coating products introduce a new generation of high-performance PTFE coating products.
PTFE / Teflon Coating Properties
PTFE / Teflon Coating is a highly useful plastic material polytetrafluoroethylene (PTFE). PTFE / Teflon Coating is one of a class of plastics known as fluoropolymers. A polymer is a compound formed by a chemical reaction which combines particles into groups of repeating large molecules. Many common synthetic fibers are polymers, such as polyester and nylon. PTFE / Teflon is the polymerized form of tetrafluoroethylene. PTFE has many unique properties, which make it valuable in scores of applications. It has a very high melting point, and is also stable at very low temperatures. It can be dissolved by nothing but hot fluorine gas or certain molten metals, so it is extremely resistant to corrosion. It is also very slick and slippery. This makes it an excellent material for coating machine parts which are subjected to heat, wear, and friction, therefore the first choice for most enigineering solutions. PTFE has low electrical conductivity, so it makes a good electrical insulator. and it is essential to the manufacture of semi-conductors. PTFE is also found in a variety of medical applications, such as in vascular grafts, although there are restrictions as to the use of PTFE / Teflon Coating associated with medical devices, please consult us on specific application requirements.
