Rostec begins polymer deliveries for Russian aerospace industry.

The Russian State Corporation Rostec has developed the country’s first industrial production technology of an overstable polymeric material for hi-tech industries.

The first experimental batches of polyaryletheretherketone (PEEK) are already being supplied to the customers, including enterprises, which are affiliated with Rostec, the State Atomic Energy Corporation Rosatom and the Federal Space Agency Roskosmos, Rostec’s press service said.

"PEEK is designed for application in extreme conditions such as high temperatures or severe atmosphere. This polymeric material is resistant to mechanical and electric loads as well as to radiation in outer space," Rostec said.

The PEEK synthesis technology has been developed by the JSC Research Institute of Plastics named after G.S. Petrov (JSC "NIIPM"), which has patented its innovation. The institute is an affiliate of the RT-Chemcomposite holding company, which has already launched the polymer’s fine chemical production and is working on the industrial production technology.

PEEK is resistant to temperatures ranging from 200 to 260 degrees Celsius and preserves its properties up to 300 degrees Celsius. The polymer is also functional in low temperatures close to minus 196 degrees Celsius. PEEK’s overstable properties make it possible to apply it in the iron and steel industry, the nuclear industry, the aircraft-building industry, engineering, the aerospace industry, the electrical engineering industry, medicine and other branches.

"The Russian industry will need 27 tons of PEEK annually in 2019-2024. So far the polymer has been imported from Europe and the United States. The technology developed by the RT-Chemcomposite holding company of the Russian State Corporation Rostec as part of an import substitution program will make it possible to replace all foreign analogues," Rostec’s Executive Director Oleg Yevtushenko said.
