Tips: What is VITON?
VITON is a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main or side chains. The introduction of fluorine atoms gives rubber excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance, which has been widely used in aerospace, aviation, automobile, petroleum and household appliances and other fields.
