Also known as tetrafluoro plate, Teflon plate and polytetrafluoroethylene plate processing. Wide temperature range (-200C ~ 260C). It is corrosion resistant to almost all chemicals (except some fluorides and alkaline molten metal). Excellent mechanical properties include aging resistance, which is used for bending and swinging. Excellent flame retardancy, excellent insulation characteristics, low water absorption, self-lubricating and non-sticky and a series of unique properties. Polytetrafluoroethylene (PTFE) has diffuse transmission characteristics, and its transmittance in ultraviolet band is better than other materials, and its visible infrared transmittance is acceptable, so it can be used in various sensors in ultraviolet-visible near infrared band.
