E9 ultra-high-modulus glass fiber reached tank-furnace mass production in 2021. The company reported modulus above 100 GPa and described E7, E8 and new electronic-yarn formulations as operating efficiently and stably, with customer certification and promotion. The numerical modulus is a company disclosure, not an independently reproduced test result. This production-stage milestone follows the laboratory-stage confirmation for E9 in the 2018 filing.
R&D investment reached RMB 552,223,387.50, entirely expensed, or 2.80% of revenue. The operating account discusses digital applications across the fiber value chain and manufacturing process, alongside glass-formulation development. The expenditure supports a broad research programme. It is not identified solely as E9 development cost or as the budget for any one new production line.
The annual report explains glass-fiber manufacture from mineral inputs such as pyrophyllite, kaolin, limestone and quartz sand through proportioning, high-temperature melting, drawing, drying and winding. Fibers serve as composite reinforcement, electrical insulation, thermal insulation and circuit-board substrates; these are inputs for downstream manufacturers, not proof that Jushi sells finished vehicles or wind turbines. Its industry description of alkali-free glass exceeding 95% of output is not Jushi’s own product mix. Research spans glass formulations, sizing chemicals, fiber products, composite applications, manufacturing equipment, cleaner production and intelligent manufacturing. FY2021 research investment was CNY 552,223,387.50, all expensed, equal to 2.80% of revenue, with 1,792 research personnel. These resources are not allocated solely to E9 or any one line. Management reports E9 tank-furnace mass production and modulus above 100 GPa, and certification/promotion of E7, E8 and new electronic-yarn formulations. The modulus and qualification claims are issuer disclosures; no independent comparative test, named certification customer, grade sales or separate saving from each digital initiative is supplied here. Leadership and awards are condensed rather than used to prove technology or commercial success.
