Jiangshan Daqin New Material Technology Co., Ltd., widely known as
Daqin Silicone, has solidified its foothold in China’s competitive
Silicone sealant industry after completing a full production capacity upgrade in early 2026. Founded in 2017, the enterprise has evolved from a regional silicone material processor into a comprehensive manufacturer integrating independent production, research and development, and global sales. Covering a factory area of 14,000 square meters, the company has deployed fully automated twin-screw silicone glue production lines, marking a key leap in intelligent and large-scale manufacturing, with its annual comprehensive output capacity officially reaching 20,000 tons of high-quality silicone sealants. This capacity expansion not only doubles the company’s market supply capacity but also lays a solid foundation for it to undertake large-scale engineering orders and long-term cooperative projects at home and abroad.
For years, Daqin Silicone has focused on the research, production, and sales of construction-grade and industrial-grade silicone sealants, breaking the long-term monopoly of foreign high-end brands in the mid-to-high-end sealant market. Before the capacity upgrade, the company’s production lines were restricted by semi-automatic processes, resulting in limited order delivery capacity and low production flexibility. The newly launched fully automated twin-screw production lines realize full-process precise control from raw material proportioning, high-speed stirring, constant-temperature curing to finished product filling and packaging. The intelligent production system effectively eliminates manual operation errors, improves product uniformity and stability, and increases the finished product yield from 92% to 99.2%, far exceeding the industry average level.
The capacity expansion project also optimizes the company’s production cost structure and supply chain efficiency. Through centralized raw material procurement and automated streamlined production, Daqin Silicone has reduced unit production costs by approximately 12%, while ensuring stable product quality. Its core product portfolio covers neutral structural silicone sealants, weather-resistant curtain wall sealants, door and window special sealants, and industrial waterproof sealants, fully covering the mainstream demand scenarios of construction engineering, home decoration, and industrial manufacturing. Industry insiders pointed out that with the completion of the 20,000-ton capacity layout, Daqin Silicone has become one of the most cost-effective and productive private silicone sealant manufacturers in East China, with strong market competitiveness in both domestic bulk orders and overseas small-batch customized orders.
In the follow-up layout, Daqin Silicone stated that it will continue to optimize production line efficiency, launch phased equipment upgrading plans, and expand the R&D and production proportion of high-performance functional sealants. While stabilizing the basic market of conventional building sealants, the company will further tap the incremental market of industrial special sealants, relying on large-scale capacity advantages to expand market share in the national and global silicone material markets, and gradually build a well-known Chinese silicone sealant brand with both quality and scale advantages.
