PTFE is widely used in medicine.
It includes artificial blood vessels and patches for soft tissue regeneration and surgical sutures for blood vessels, heart, general surgery and plastic surgery. PTFE is used as filling material in nose augmentation and mandible plastic surgery. ?
Polytetrafluoroethylene products are widely used in telecommunications, computers, testing and measurement, national defense, aviation and aerospace markets and many other high-performance and challenging fields. ???
As a medical material, expanded PTFE has excellent mechanical properties, durability, stability and biological adaptability. It will not cause rejection of the body, has no physiological side effects on the human body, and has the characteristics of multi microporous structure. It was first made into human blood vessel for clinical application since the 1970s. Now, due to its excellent performance, expanded PTFE has been widely used in clinic
PTFE material is used as anti sticking material. It has small surface tension of solid material, does not adhere to any substance, and also has excellent characteristics of high and low temperature resistance and non-toxic. Therefore, as a coating, PTFE is often used as anti sticking lining of tableware, and PTFE is mainly used as inner liner of non sticking pot and microwave oven. At the same time, it can be used for microwave drying conveyor belt in food industry and heat sealing sleeve anti sticking material in polyethylene bag.
Development of polytetrafluoroethylene
PTFE, as the main variety of fluorine-containing materials, has a very broad market application prospect, and China has a unique resource advantage, which is a key industry encouraged by the state.
At present, China has become a major producer of PTFE in the world, but there is still a big gap with foreign countries in terms of technology and products, especially in the research and processing application level of PTFE modification. Therefore, at present, domestic production enterprises and scientific research institutions focus on the research and development of PTFE application and processing technology while improving PTFE production technology, so as to promote the connotation of China's PTFE industry.
