How to understand the cold flow phenomenon of polytetrafluoroethylene?
Thread Content
I have seen a lot of literature and papers saying that cold flow occurs in tetrafluoroethylene materials. What is cold flow? What are the dangers? How to prevent it? Can an expert tell me about it? I will get extra points for replying. Thank you.
PTFE has "cold flow properties". That is, plastic deformation (creep) of material products under long-term continuous load can be added with fiber material reinforcement, especially carbon fiber, which can greatly enhance the strength without affecting the use temperature and corrosion resistance. It's just that the color has turned black.
