Pulextrusion combines Thermopreg™ Pultrusion
Thermoplastic can provide surface functions (color, texture) or inexpensive section filling. When strategically located in an extruded Profile
, Thermopreg™ provides high stiffness and reduced thermal expansion.Rovings
are pulled from a package through a tensioning device and into an infrared or convection oven to heat the material from 200°C to 220°C.
The molten Thermopreg™ rovings are drawn over a series of heated impregnation bars before entering a cross head extrusion die.
