Performance advantage
High temperature resistance - use working temperature up to 250 °C.
Low temperature resistance - good mechanical toughness; 5% elongation even at temperatures down to -196 °C.
Corrosion resistant - inert to most chemicals and solvents, resistant to strong acids and bases, aqua regia and various organic solvents.
Weather resistant - the best aging life in plastics.
Highly lubricated – the lowest coefficient of friction in solid materials.
Non-adhesive - is the smallest surface tension in solid materials and does not adhere to any substance.
Non-toxic - physiologically inert, long-term implantation of artificial blood vessels and organs without adverse reactions.
