PTFE Extruded Tube Product Introduction

Product Overview

PTFE extruded tubes are high-performance tubing products continuously formed using pure Polytetrafluoroethylene (PTFE) raw material through high-temperature extrusion processes. With excellent chemical inertness and temperature resistance, they are an ideal choice for fluid transfer systems in chemical, electronics, medical and other industries.

Core Advantages
