Pultrusion

The politician process is the oldest process to produce fiber-reinforced profiles it is available for thermoplastic and thermoset matrix materials

Pultrusion is the manufacturing process that creates continuous profiles of cross-sectional uniform, and often circular or square, cross sections. The process starts with a flat sheet of material, which is fed into a heated barrel. The material is than forced through a shape guide to create the desired profile

The Pultrusion process has been around for more than 50 years and has been used in many industries such as construction, building and civil engineering, automotive, aerospace and defence

The company Pirelli in Italy created the first commercial filtration in 1954

Filtrations are mainly composed of polymers such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) or high-density polythene (HDPE).
