The advent of nonstick cookware has greatly simplified people's lives, eliminating the worry of accidentally burning meat while cooking or fish sticking to the pan when frying. The appearance of these nonstick pans differs little from ordinary ones; the key lies in an additional layer of polytetrafluoroethylene (PTFE) coating on the inner surface. Leveraging PTFE's exceptional thermal properties, chemical resistance, ease of cleaning, and non-toxic nature, this popular kitchenware was developed. PTFE, hailed as the “King of Plastics,” boasts outstanding chemical corrosion resistance and aging resistance—even aqua regia struggles to corrode it. While ordinary plastic products are prone to aging—where items that initially appear fine develop cracks or even break after three to five years or a decade—products made from “Plastic King” can withstand outdoor exposure to sun and rain for two to three decades without damage. Consequently, it is widely used in daily life and chemical engineering.

The “King of Plastics” is also extensively employed in industrial absorption towers and corrosion-resistant vessels. With ongoing improvements to its properties, its applications in modern life, agriculture, industry, national defense, and science and technology will continue to expand. In Western developed countries, nonstick cookware has long been commonplace. In China, its adoption began in the 1990s, and its unique properties are increasingly recognized by consumers.
