At the beginning of 2026, Mount Huangshan Meijia New Material Co., Ltd. and Anhui Hecheng Chemical Co., Ltd. officially announced the strategic cooperation, and the two sides will jointly layout the field of electronic grade vinyl silicone oil. This cooperation aims to integrate the advantageous resources of both parties in the fields of synthetic material manufacturing and fine chemicals, and launch an impact on high-end application markets such as semiconductor packaging, new energy vehicles, and optical devices. The goal is to directly target foreign technology monopolies and achieve import substitution of key materials.


As a national high-tech enterprise, Mount Huangshan Meijia has long focused on the R&D and manufacturing of synthetic materials and special chemicals, and its business covers the manufacturing of synthetic materials, the sales of special silicone products, and the import and export of goods. Anhui Hecheng has mature industrial layout and channel advantages. The cooperation between the two parties is not only a natural complementarity of the industrial chain, but also a shared optimism about the prospects of the high-end silicone oil market.


Electronic grade vinyl silicone oil is the "heart material" of high-performance addition liquid silicone rubber, electronic potting adhesive and thermal conductive gel. Its purity, metal ion control index and stability of molecular weight distribution directly determine the reliability and service life of downstream electronic devices. Currently, the traditional general-purpose silicone oil market is deeply mired in a price war, with generally low gross profit margins, while electronic grade silicone oil is expensive and scarce in the market due to its extremely high technical barriers. The huge profit margin is driving industry leaders to accelerate their transformation towards the high-end track.
