PTFE – or polytetrafluoroethylene – is a thermoplastic fluoropolymer. PTFE products have the highest operating temperature of any fluoropolymer and have extremely low coefficient of friction, fair abrasion resistance and good chemical resistance. Usually, these coatings are being used where a dry lubricant or low friction, or corrosion resistant coating is necessary.
FEP – or fluorinated ethylene propylene – non-stick coatings melt and flow during baking to provide a smooth non-porous surface with excellent abrasion resistance. Because the coating is non-porous its chemical resistance is superb. FEP coatings are extremely non-wetting and convince with a very low coefficient of friction.
As coating materials we use well-known brands like Teflon®, Greblon®, Ilaflon® or Xylan®.
