Advantage of PTFE：
High Temperature Resistant, working temperature can be 250℃
Low Temperature Resistant, can continual 5% elongation even 196℃
Corrosion Resistance——Show Inertia to most chemicals and solvents, can stand
acid alkali, water and variety of organic solvents.
Weather-Resistance——With best aging with a plastic life. High lubrication-with the lowest friction coefficient in solid materials.
Inadhesion——With the lowest surface tension of the solid materials
Non-Toxic——With physical inertia, can be artificial blood vessels and organs implanted without adverse reaction.
