Abbreviation: PTFE
　　
　　Chinese Name: polytetrafluoroethylene
　　
　　Polytetrafluoroethylene is known as the “king of plastics”， with a service temperature of - 190-250 ℃，
　　
　　Advantage
　　
　　High temperature resistance - operating temperature up to 250 ℃。
　　
　　Low temperature resistance - good mechanical toughness; 5% elongation can be maintained even when the temperature drops to - 196 ℃。
　　
　　Corrosion resistance - for most chemicals and solvents, it is inert, resistant to strong acids and bases, water and various organic solvents.
　　
　　Polytetrafluoroethylene pipe
　　
　　Weather resistant - has the best aging life in plastics.
　　
　　High lubrication is the lowest friction coefficient among solid materials.
　　
　　No adhesion - the minimum surface tension in a solid material, no adhesion of any substance.
　　
　　No toxicity - physiological inertia, no adverse reactions after long-term implantation as artificial blood vessels and organs.
　　
　　Electrical insulation - resistant to 1500 volts of high voltage.
