On November 6, China`s leading high-temperature CPI (Colorless Polyimide) Films technology company, LNAK Advanced Materials Technology Group, revealed that the company’s high-temperature colorless and transparent polyimide products developed in cooperation with LN University of Science and Technology have made significant progress and are currently used in Mars rover.
On August 28, 2019, a national key project with an annual output of 1,000 tons of high temperature resistant, colorless and transparent polyimide materials developed by LNAK and LN University of Science and Technology settled in the aromatics and chemical fiber raw material base.
The project covers an area of 105,000 square meters with a total investment of 400 million yuan. Among them, the first phase of the monomer project investment is about 300 million yuan. After the project is completed and put into production, it will produce 360 tons of transparent polyimide (CPI) monomers and realize sales revenue of 1 billion yuan, which can effectively solve China's high-end polyimide And the "stuck neck" problem in the production of wide-format CPI film.
LNAK`s high temperature resistant colorless and transparent polyimide material full industrial chain project has independent intellectual property rights and the production technology of the entire industrial chain from monomer to high temperature resistant colorless CPI film and functional composite film. To the entire industrial chain production line of CPI film. In addition to applications in the aerospace and aviation fields, this product is used as an optical film substrate and is mainly used in the fields of optoelectronic products such as flexible displays, organic photovoltaic cells, terminal touch modules, and optical sensor components.
