PULEXTRUSION
Pulextrusion combines COMFIL® pultrusion with thermoplastic extrusion. Thermoplastic can provide surface functions (colours, texture) or inexpensive section filling. When strategically located in an extruded profile, COMFIL® provides high stiffness and reduced thermal expansion.

Key Processing Points:
- Rovings are pulled from packages through tensioning devices and into an infrared or convection oven to heat the material from min. 25 degree C over the melting temperature of the matrix material.
- The molten COMFIL® rovings are drawn over a series of heated impregnation bars before entering a cross head extrusion die.
