ProTec acquires PolymersNet

News International-French

The company based in Lampertheim/Germany is specialized in design, construction, and commissioning of powerful systems for manufacturing of long-fiber reinforced thermoplastics (LFT) using the pultrusion technology. 

ProTec, which previously distributed these systems exclusively as a sales partner, has now taken over PolymersNet assets. In addition to patents, experts and the supply chain, these include the LFT production line that had been used up to now for process and material developments and for specific customer trials in Lampertheim. This facility will now be set up in a specially designed technical center at the ProTec headquarters in Bensheim, where it will also be upgraded and extended.

Efficient technology for high-grade materials
The LFT pultrusion lines are customized for the economical production of high-quality thermoplastics with fibers of pellet length. Long-fiber reinforced thermoplastics with fiber lengths (pellet lengths) of 7 mm to 25 mm are the usual industry standard. The fiber strands – made of either glass or carbon fibers – are isolated to create the filaments before being uniformly coated (impregnated) with the polymer melt in the impregnation die. After a cooling process the fiber-polymer strands are then pelletized. Fiber content of up to 60 percent by weight and plant sizes with throughputs of up to 1,200 kg/h can presently be realized.

Long-fiber reinforced thermoplastic parts produced on injection molding machines result into high-strength and lightweight components that also offer excellent surface quality. ProTec system technology is designed for the production of a broad range of materials with different types of fiber reinforcement and very diverse polymer matrices. The technology has now developed to the stage where it can also be used to extract LFT reliably from carbon-fiberreinforced PP – a material combination that was previously difficult to produce.
