As a critical "protective barrier" in industrial production and high-end manufacturing, PTFE Liner (polytetrafluoroethylene liner) has become an indispensable core component in multiple industries due to its outstanding comprehensive performance. Made of high-purity PTFE resin through specialized molding and processing technologies, this liner inherits the material's inherent advantages: excellent corrosion resistance to withstand strong acids, alkalis, and organic solvents; stable temperature resistance ranging from -200℃ to 260℃; ultra-low friction coefficient for smooth media conveying; and reliable insulation to ensure safe operation of equipment.
