Modified PTFE reduces porosity and cold flow and welds better, for welded or continuously loaded parts.
Modified PTFE is a Modified Grade grade within PTFE (Teflon), widely used in industrial CNC machining due to its balanced mechanical, thermal, and machinability performance.
Modified PTFE reduces porosity and cold flow, with improved weldability, suitable for parts requiring welding or long-term pressure service.
Modified PTFE grades are commonly used in the following fields and scenarios; our CNC machining services can provide custom parts for these industries.
Modified PTFE demonstrates the following core advantages in CNC machining and end-use applications.
The following are key process points when machining PTFE (Teflon) material, to ensure part quality and machining efficiency.
Use sharp carbide or high-speed steel tools with large positive rake angles to ensure light cutting rather than material extrusion.
PTFE is prone to creep; use low-clamping-stress methods (soft jaws/vacuum suction) and symmetrical layered material removal, with intermediate annealing when necessary.
Allow 24-hour stress relief after final machining before final inspection; batch parts are machined with identical parameters, achieving consistency up to ±0.01mm.
PTFE scratches easily and attracts dust via static; handle with gloves throughout, use dedicated workstations, and ultrasonically clean before shipment.
Besides Modified PTFE, PTFE (Teflon) offers several other grades with different characteristics. Click to view details.
