Established in June 2007, Jiangsu Yongjia Electronic Materials Co., Ltd. has spent over eighteen years mastering the art of high-performance polymer materials. As a premier Wholesale Injection Molding Rubber Materials Manufacturer & Factory, we provide a bridge between advanced chemical engineering and practical industrial application.
Our 16,000-square-meter facility in Nantong operates as a hub for innovation, where we integrate R&D, large-scale manufacturing, and global logistics. We specialize in functional tapes and materials that are critical for modern injection molding components, electronic packaging, and automotive shielding.
The global demand for specialized injection molding rubber materials and functional electronic tapes is currently experiencing an unprecedented surge. As industries transition toward miniaturization and high-frequency communication (5G/6G), the role of material science has become more critical than ever. In the modern industrial landscape, these materials are no longer just "packaging" or "protection"—they are integral components that ensure the thermal stability, electrostatic discharge (ESD) safety, and mechanical integrity of high-value products.
We are seeing a massive shift toward sustainable and high-performance elastomers. The trend is moving away from generic plastics toward engineered materials that can withstand extreme environments. Key developments include:
International buyers are increasingly seeking factories that offer "One-Stop Solutions." From raw material formulation to final slitting and packaging, reliability in the supply chain is the top priority for Fortune 500 enterprises.
Whether it's automotive sensor overmolding in Germany or semiconductor packaging in Vietnam, our materials are engineered to meet localized technical standards and environmental regulations (RoHS/REACH).
As a leading Chinese factory, we combine cost-efficient production with high-tier R&D. Our location in Nantong provides us with logistics advantages that translate to faster lead times for our global partners.
High-durability materials for vehicle sensor protection and wiring harness insulation.
Precision materials for metal stamping processes and component carrier systems.
Anti-static cover tapes ensuring the safe transport of semiconductors.
Flame-retardant acetate tapes for internal circuitry and home electronics.
Our expertise lies in the precise control of adhesive properties. For our Heat Seal Cover Tapes, we utilize advanced thermoplastic coatings that ensure a consistent peel force—vital for high-speed SMT (Surface Mount Technology) picking. For Self-Adhesive variants, we focus on aging resistance, ensuring that the bond remains stable even after months of storage in varying climates.
Different industrial environments demand different material bases. Our Acetate Cloth Tape provides superior flexibility and absorption for resins, while our Glass Fiber Tape offers unparalleled tensile strength for heavy-duty bundling. As a specialized manufacturer, we understand that "one size does not fit all," which is why we offer customized material formulations to match specific injection molding or electronic protection requirements.
With 18 years in the industry, Jiangsu Yongjia has navigated the complexities of global trade and technical evolution. Our R&D laboratories are equipped with state-of-the-art testing equipment to measure peel strength, surface resistivity, and thermal decomposition, ensuring every batch meets our "Reliability First" mandate.
