POLYTETRAFLUORETHYLENE / PTFE / ANULON 220

ANULON-220 Polytetrafluoroethylene (PTFE) popularly known as Teflon is an inert, non-toxic material well known for its remarkable properties, such as, self-lubrication, non-adherence, non-in flammability and immunity to chemicals or solvents. Its dielectric constant and loss factor are low and stable across a wide temperature and frequency range.Impact strength is high but tensile strength, wear resistance and creep resistance are low in comparison with other engineering plastics. Glass, bronze, carbon and graphite are added to improve specific mechanical properties to suit individual application. Its coefficient of friction is lower than almost any other material. Having excellent thermal properties, it has a wide working temperature range from – 80℃ to 250℃.
