Bülte announced a new series of products based on organic thermoplastic polymer used in engineering applications, PEEK. Considered one of the top-of-the-range plastics, PEEK is a thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures (oils, hydrocarbures). Because of its robustness, it is used in particular to build items used in demanding applications, including bearings, piston parts, pumps, compressor plate valves and electrical cable insulation.
Due to its low flammability (UL 94), it is one of the few plastics compatible with ultra-high vacuum applications, which makes it suitable for many types of industries. Lastly, being inferior in density compared to metal makes it an excellent substitute in cases where weight is a limiting factor in the final product.
