-The length is continuous,if you purchase 5 x 1meter, you will get 5 meters in one go。-Polytetrafluoroethylene (F4, PTFE) is the engineering plastic material with the highest temperature resistance (280-300°C), the highest electrical resistance (45KV/mm), the strongest acid resistance, alkali resistance, the most viscous resistance, the slippery and wear resistance. It is widely used in machinery, automotive, electronics, chemical, aerospace, medical, communications, transformer and other industries。
Main characteristics
1. High temperature resistance, long-term use temperature 200-260°C;
2. Aging resistance, the best aging life of plastics, can be used outdoors for a long time。
3. High lubrication, with the minimum friction coefficient (0.04) in plastics, is an excellent self-lubricating material, and the friction coefficient does not change with temperature。
4. Non-sticky, with the smallest surface tension in solid materials, the inner wall of the pipe is not easy to adhere to colloids and chemicals;
5. Non-toxic and physiological inertia。
6. Excellent electrical properties. PTFE is a highly non-polar material with good dielectric property, great resistance and dielectric constant of about 2.0. PTFE is the smallest of all electrical insulating materials and is an ideal class C insulating material。
7. High chemical stability: It can withstand all strong acids, including Aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, strong alkali, strong oxidant, reducing agent and various organic solvents. It is very suitable for high purity chemical feeding。
