Teflon Coating Roll
Teflon Coating Roll
Teflon Coating Rollmade by coating the roll surface with Teflon (fluorine resin), which forms highly stable compound as a result of strong chemical bond between fluorine and carbon, and nearly perfect chemical inertness, heat resistance, non-adhesion, outstanding insulation stability, and low coefficient of friction. Teflon coating roll is made by using the same process as conventional rolls, except for applying Teflon coating at the end of the process.
