PTFE Extrusion Process

Pre-sintered PTFE resin is plasticized in an extruder (300-380°C) and driven through a precision die by a high-pressure screw (10-40 MPa) to continuously form tubes, rods, or profiles. Subsequent sintering ensures material densification.  

 

Advantages

  • High-efficiency continuous production
  • Complex cross-section shaping
  • Performance optimization 
  • Low material waste


Typical Applications

  • Corrosion-resistant pipelines (DN10-DN300)  
  • 5G high-frequency cable insulation (dielectric constant 2.1)  
  • Expanded PTFE (ePTFE) sealing tapes (compression recovery >80%)  
  • Minimally invasive multi-lumen catheters (wall thickness 0.2 mm ±0.03)
