1. PTFE products can be continuous used in 195 ~ 260 ℃, can be used in a short time under the environment of 300 ℃;
2. PTFE products can be used in almost all strict chemical mediator (except for F elements and molten alkali metals, they have a certain corrosive effect on PTFE products);
3. PTFE product has a low coefficient of friction and good self-lubricating property;
4. PTFE products have excellent dielectric properties
