PTFE 四氟垫

Use the advantages of PTFE gaskets:
High temperature - use temperature up to 250 ℃.
Low temperature - has good mechanical toughness; even if the temperature dropped to -196 ℃, but also to maintain a 5% elongation.
Corrosion-resistant - for most chemicals and solvents, showing inertia, the ability of acid and alkali, water and various organic solvents.
Weather - the best plastic in the aging life.
High lubrication - is a solid material in the lowest coefficient of friction.
Do not adhere to - is a solid material in the smallest surface tension, does not adhere to any substance.
Non-toxic - with physical inertia, as a long-term implantation of artificial blood vessels and organs in vivo without adverse reaction
