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.
