The advent of "non-stick pan" has brought great convenience to people's lives. People don't have to worry about cook the meat anymore, but they will burn if they are not careful. When frying fish, the fillets will stick to the wall of the pot. This non-stick pan has nothing to do with the appearance of ordinary pan, but a layer of PTFE is coated on the inner surface of the pan, and this popular kitchen utensil is made by using the excellent thermal performance, chemical performance, easy cleaning performance and non-toxic performance of PTFE.
PTFE is known as the "king of plastics", which has good chemical corrosion resistance and aging resistance, and aqua regia is not easy to corrode. Ordinary plastic products are prone to aging. Things that looked good in the past will crack or even break after three to five years or ten years. Products made of "Plastic King" can be placed outdoors, and will not be damaged in 20 or 30 years regardless of sun and rain. Therefore, it is widely used in life and chemical industry.
