recubrimientos Dupont Chemours Teflon

Teflon ® coating


Like many great human inventions, Teflon® was discovered by chance: while Dr Roy J. Plunkett was experimenting with a coolant in 1938, he observed that a compressed, frozen TFE (tetrafluoroethylene) sample polymerised in a beaker, giving rise to the first known fluoropolymer: polytetrafluoroethylene (PTFE). This new material presented high chemical and thermal resistance, apart from having other extremely useful properties. It was patented by DuPont in 1941 with the name Teflon® and was mainly marketed in the form of bakeware items.

Teflon ® product range, properties and benefits

All the PTFE Teflon® coatings are made without PFOA and can be used in continuous temperatures reaching maximum values up to 260°C. There is a wide offer available, particularly in the kitchenware sector:

The original Teflon® Classic has non stick properties and excellent value for money in everyday use. It is a bilayer system of at least 25 microns.

Teflon® Select lasts longer as it is designed for more intensive use: it is a trilayer system with a minimum thickness of 35 microns.

Teflon® Xtra is a reinforced coating system.

Teflon® Platinum is even more resistant to abrasion and scratching, as it withstands the use of metal utensils and even abrasive scouring pads. It is also a trilayer system with a thickness of up to 40 microns and microparticles of an extremely hard material.

In recent years Teflon® has continued to offer innovations such as Teflon® Infinity, a four-layer system with a modern, attractive stone finish in different colours, and Teflon® Profile which, although a trilayer system, has greater resistance to scratching thanks to a unique technology and a wrinkled appearance similar to the skin of a reptile.

Teflon® industrial non-stick coatings can be applied using spray techniques, in both liquid and powder form, and are so versatile that they can be applied to parts with a wide variety of sizes and shapes. It can also be combined with other materials that have different properties, adding specific benefits for special needs. So if we consider its benefits such as its high thermal resistance, chemical inertness, good dielectric stability and low friction coefficient, Teflon® non-stick coatings are perfect for the industrial sector as when applied, their friction coefficients may reach 0.02- 0.15, depending on the load, speed and coating type. Furthermore, the use of Teflon fluoroplastics is beneficial in manufacturing semi-conductive materials: in addition to Teflon® PTFE, products such as Teflon® PFA and Teflon® FEP can be used, which protect from corrosion in multiple aggressive industrial processes, such as those used in the chemical industry.
