PTFE is typically soft and weak polymers, macromolecules gravity between smaller, less stiffness, hardness, strength, and in the long-term will deform under the action of stress.
PTFE easily thrown when loading creep, is typical of a cold flow of the kind of plastic. PTFE creep compressive stresses, temperature and varies with the degree of crystallinity, high temperature creep higher. The crystallinity of PTFE in 55% 80%, creep up to 2% when when the crystallinity of 55% and 80%, creep to grow quickly. Mechanical performance properties of PTFE is the coefficient of friction small, 0. 110.10, in an existing plastic material, and all project materials in the least. PTFE has a mechanical function is good, we take a look at how its mechanical function. Its friction coefficient is extremely small, only 1/5 of polyethylene, which are important characteristics of perfluorocarbon. Because of Intermolecular fluorine-carbon chain is very low, so the Teflon non-stick.
