In the current global industrial landscape, the term "Main Rubber" has evolved beyond simple elastic materials. It now encompasses a sophisticated range of polymer-based functional tapes, heat-seal adhesives, and synthetic cloth carriers that are vital to the semiconductor, automotive, and consumer electronics industries. As a leading manufacturer, we understand that the reliability of a smartphone, the safety of an electric vehicle (EV), and the precision of a chip carrier depend on the high-quality chemical formulations of these rubberized adhesives.
The global market is witnessing a massive shift toward miniaturization. As electronic components get smaller, the demand for high-precision carrier tapes and cover tapes—often referred to in the trade as "Main Rubber products" for packaging—has skyrocketed. Suppliers must now balance physical flexibility with extreme thermal stability, ensuring that components remain protected during high-speed SMT (Surface Mount Technology) processes.
Established in June 2007, Jiangsu Yongjia Electronic Materials Co., Ltd. has dedicated 18 years to perfecting the art of functional tape manufacturing. Our facility in Nantong spans 16,000 square meters, housing advanced R&D laboratories and high-capacity production lines.
We are not just a supplier; we are a comprehensive service provider. From the initial R&D of high-temperature heat-seal tapes to the mass production of acetate cloth tapes, our focus is on providing the backbone materials that modern electronics require. Our "Main Rubber" adhesive expertise ensures every roll of tape meets international standards for durability and performance.
