The use of fluoropolymers for non-stick cooking utensils

  • P Thomas


The formulation of non-stick coatings for cooking utensils is probably more complicated than had been thought. It has been shown that the addition of copolymers to PTFE greatly improves the properties of the coating.

The problem of having a ‘non-stick’ coating ‘sticking’ to a metal substrate is partly solved by the fluoropolymer stratifying to the coating surface. FEP is the copolymer of choice for adhesion of primers to very smooth surfaces where there is lack of mechanical adhesion.

The abrasion resistance and barrier properties of the coating are enhanced by the addition of PFA due to the better mechanical properties and lower crystallinity of this copolymer.

In the end, non-stick coatings are a complex blend of several fluoropolymers (homopolymer and copolymers), bonding resins and pigments. Fluoropolymers have not been developed essentially for non-stick cooking utensils technology, but today the consumer benefits from the most advanced non-stick technology due to the requirement of industry to search for increasingly improved performance with existing materials.
