It currently owns 2 wholly-owned subsidiaries (Kunming Yunneng Chemical Co., Ltd. and Yunnan Tianju Chemical Co., Ltd.) and 4 controlling subsidiaries (Yunnan Tianye Chemical Co., Ltd., Yunnan Puyang Coal Chemical Co., Ltd., Yunnan Energy Investment Silicone Materials Technology Development Co., Ltd., and Yunnan Yongchang Silicon Industry Co., Ltd.). Adhering to an innovation-driven development strategy, the New Materials Company has been granted 125 invention patents and 163 utility model patents, and has obtained certification for ISO 9001 Quality Management System, ISO 14001 Environmental Management System, ISO 45001 Occupational Health and Safety Management System, and ISO 50001 Energy Management System. Yunnan Energy Investment Silicone Materials Technology Development Co., Ltd., a controlling subsidiary established in 2019, is the first organosilicon new materials producer in Yunnan Province. It has invested in a 400,000 tons/year organosilicon monomer and supporting project. The first phase (200,000 tons/year) was completed and put into operation at the end of 2021, achieving full production capacity in May 2022, with stable operation and consistent product quality. Its main products include hydrolyzate, DMC, linear silicone, 107 gum (including low-viscosity and low-volatility grades), 110 gum, D3, D4, D5, D6, vinyl silicone oil, dimethyl silicone oil, methyltrichlorosilane, and trimethylchlorosilane.

Kunming Yunneng Chemical Co., Ltd., a wholly-owned subsidiary established in 2018, operates production facilities with an annual capacity of 100,000 tons of ion-exchange membrane caustic soda and 100,000 tons of PVC. Its main products include caustic soda, PVC, hydrochloric acid, and liquid chlorine. The company has obtained certification for Safety Standardization Level II Enterprise as well as ISO 9001, ISO 14001, and ISO 45001 management systems. Yunnan Yongchang Silicon Industry Co., Ltd., a controlling subsidiary established in 2005, has an annual production capacity of 200,000 tons of metallurgical-grade silicon. Its main products include industrial silicon grades 2202, 3303, 421, 441, etc., with proven silica ore reserves of over 4 million tons. The company has gathered 7 high-level talents at or above the provincial level (including experts receiving the State Council Special Allowance and provincial industrial technology leaders). Yunnan Tianye Chemical Co., Ltd., a controlling subsidiary established in 2009, operates one 100,000 tons/year zero-gap bipolar ion-exchange membrane caustic soda production unit and one 100,000 tons/year PVC production unit. Its main annual production capacities include 100,000 tons of caustic soda, 100,000 tons of PVC, 150,000 tons of hydrochloric acid, and 40,000 tons of liquid chlorine. The company is committed to green and efficient development, and has been recognized as a National Green Factory, a 2024 National Key Water Efficiency Leader Enterprise, and a Yunnan Provincial High-Tech Enterprise, among other honors. Its quality, environmental, occupational health and safety, and energy management systems operate efficiently and effectively, with 47 authorized patents accumulated to date.
