PEKK material from the French manufacturer Kimya is one of the strongest and most durable plastics not only in our product portfolio but in the entire market. The material available here is additionally reinforced with carbon fiber, which creates even greater rigidity and strength. PEKK (polyether ketone ketone) is a high performance polymer that is one of the most demanding materials in the current research situation. This material is generally used in the automotive and aerospace industries, as it can often produce parts with metal properties, but which are much lighter or can be made more easily. However, the many advantages in terms of technical properties are only possible because PEKK is processed at high temperatures. A standard 3D printer cannot process this material. The material requires a print nozzle temperature of at least 380 ° C, a print bed temperature of 150 ° C and a closed and heated 80 ° C chamber.
Characteristics of Kimya PEKK carbon
PEKK offers several advantageous properties. For example, the material is heat resistant up to 260 ° C and at the same time slows down the flame according to UL94 V0. For this reason, the material is often used to build air ducts on trains, airplanes or even cars. In addition to the high mechanical properties of the printing material, it also offers a very attractive surface quality, as is usually the case with carbon fiber reinforced filaments.
Chemical resistance of Kimya PEKK carbon
PEKK has extremely high chemical resistance. Among the materials that do not affect PEKK or have little or no absorption are acids, alcohols, alkyds, ketones, bases, esters, ethers, halogens and hydrocarbons. Nitric acid, sulfuric acid and methylene chloride are not recommended.
