Is PTFE harmful to humans?

Polytetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE, which was discovered in the late 1930s and put into industrial production in the 1940s. It is widely used in chemical, mechanical, electronic, medical, textile and other sectors.

For the most part, PTFE has essentially negligible harmful effects on the human body, with a high degree of safety due to the material's high chemical stability up to temperatures of 190°C, and is often used as a tissue substitute such as a human implant material. However, polytetrafluoroethylene may cause tumors in specific cases, such as in the high temperature environment of 200 ℃, may be harmful to the human body.
1, harmless situation: polytetrafluoroethylene in 190 ℃ or less will not cause harm to the human body, has good chemical properties, acid resistance, alkali resistance, not easy to deformation, denaturation, or absorbed by the body, more stable and safe, good tissue compatibility, less to make the human body to produce a reaction of exclusion, there is a certain biological aging effect. Therefore, PTFE is often used as an implantable material, such as being used as artificial blood vessels, organ patches and other medical products, belonging to the better biological tissue substitutes. Therefore, PTFE is generally considered to be harmless to the human body at daily temperatures up to 190°C. If PTFE is to be used as an implantable material, it should be used as an implantable material. If you want to use PTFE as a human implant material, it is recommended that you consult a doctor and then choose the material with the help of the doctor.
2, harmful situation: PTFE is classified by the World Health Organization as a class III carcinogen, mostly believed to be because of this material in the high temperature environment at 200 ℃, can release toxic gases, this may induce the occurrence of cancer. It is recommended that workers in the factory for high temperature processing of PTFE should pay attention to good protection to avoid damage to the body.
