Plastic Profiles made of Polyketon – PK
Polyketone, PK for short, is one of the semi-crystalline thermoplastic polymers. It belongs to the group of engineering plastics and is characterized by outstanding chemical resistance. Only very strong acids and alkalis can attack this plastic. In addition, PK has other technically very valuable properties such as high impact strength, low wear and low moisture absorption coupled with good elasticity. The special properties are due to symmetry in the molecular structure and flexible chains. The plastic is synthesized in a special catalyst system. The compounds used are carbon monoxide, ethylene and propylene.
Polyketone is used when high wear resistance is important. Typical applications are mechanical engineering, the automotive industry, aerospace technology and electrical engineering.
Due to high thermal sensitivity and the resulting rapid crosslinking in the processing of polyketone, only very few companies are able to process PK.
Binder + Wöhrle processes PK in the field of plastic extrusion and injection molding. B + W has different types in use and produces customized plastic pipes, hoses -profiles, -sheathings, -connections and much more in the diameter range of 0.5 – 50 mm.
