Innovation breakthrough of epoxy silicone oil empowers high-end manufacturing, domestic substitution accelerates industrial upgrading

Recently, a domestic new material enterprise successfully developed a series of high epoxy value and low viscosity epoxy silicone oil products. After testing by authoritative institutions, the epoxy conversion rate reached 98.5%, the thermal stability exceeded 300 ℃ without yellowing, and the performance indicators comprehensively benchmarked international top brands. This product, with its precise molecular chain design, achieves a dynamic balance between curing speed, adhesion, and flexibility. It has passed rigorous testing by multiple leading automotive electronics and photovoltaic module companies and has been widely used in new energy vehicle IGBT module packaging, photovoltaic backsheet adhesives, and other scenarios.

Industry experts point out that epoxy silicone oil, as a high-end organic silicon intermediate, has long been monopolized by overseas companies in core technology. This domestic breakthrough not only breaks down technological barriers, but also reduces production costs by 30% through process optimization, helping downstream enterprises achieve lightweight and weather resistant upgrades in composite materials. The technical director of a certain photovoltaic enterprise revealed that after adopting a new type of epoxy silicone oil, the anti UV aging performance of the components has been doubled, the production yield has jumped from 89% to 96%, and the annual repair cost has been saved by more than 10 million yuan.

At the policy level, the Ministry of Industry and Information Technology has included epoxy silicone oil in the "Catalogue of Key Technologies for New Materials", and local industrial funds have launched targeted support for three research and development enterprises. With the increasing demand for material performance in fields such as 5G communication and semiconductor packaging, domestic epoxy silicone oil is accelerating its penetration into high-end markets such as microelectronic packaging adhesives and aerospace heat-resistant coatings, and the collaborative innovation ecosystem of the industrial chain is gradually forming.
