Kwerk GmbH - Your Partner for Innovative Plastic Semi-Finished Products



<Semi-finished plastic products play a crucial role in the plastics industry, offering a diverse range of applications across various sectors such as automotive, electrical and electronics, mechanical engineering, medical technology, and more.

Within the realm of semi-finished plastics, there exists a wide array of product types, including PMMA XT pipes, PMMA XT solid bars, PVC-U solid bars, PP solid bars, PEHD solid bars, PE solid bars, PVC U hollow bars, PVC-U 6KT bars, PE-HD U profiles, PVC-U L profiles, PVC-U 4KT profiles, PVC-U T profiles, PVC-U flat profiles, PVDF sheets, ABS sheets, PVDF-ELS sheets, PC sheets, PEEK sheets, PEEK-MOD sheets, PET sheets, POM-C sheets, and many others.

Semi-finished FRP gratings hold numerous advantages over alternative materials, boasting exceptional chemical resistance, mechanical strength, and temperature resistance. These gratings are available in various forms, including rods, tubes, sheets, profiles, and U-sections. Notably, PVC-U hollow rods, 6KT rods, and flat profiles represent typical examples of versatile semi-finished products.

Selecting the appropriate semi-finished product depends on the specific requirements of the intended application. Key considerations include chemical resistance, mechanical properties, temperature tolerance, and dimensional stability. Each material possesses distinct properties and applications that render it suitable for specific needs.

Semi-finished plastic products offer an extensive range of possibilities to cater to diverse applications. They serve as a cost-effective and versatile alternative to alternative materials, finding utility across numerous industries. In essence, semi-finished plastic products stand as an indispensable component within modern manufacturing processes.
