On July 9, 2021, Jiutian Xingge and the Aerospace Port signed the "Jiutian Xingge (Haiyang) Aerospace Industrial Park Project Investment Cooperation Agreement", successfully taking the first step in the construction of the Haiyang base.

        Low temperature thermal insulation technology, including buffer layer preparation technology, foam preparation technology, sealing reinforcement layer preparation technology, high temperature heat protection layer preparation technology. Low temperature insulation technology is suitable for liquid methane (-172℃), liquid oxygen (-183℃), liquid hydrogen (-253℃) tank insulation, and can be used for the production of tanks of various diameters. It has low temperature insulation foam preparation technology, low temperature and high temperature heat protection system design technology, and production process technology. Low-temperature thermal insulation foam has small pore size, high toughness, low thermal conductivity, closed cell rate greater than 95%, and excellent comprehensive mechanical properties. Cryogenic insulation technology can be used to insulate cryogenic pipelines for short-term or long-term use. Foam spray can be sprayed by hand, poured, or sprayed by machine; it can be used for military or civilian use.
