China Adhesives and Sealants Expo 2025

On September 16, 2025, Heynova (Shanghai) New Material Technology Co., Ltd. participated in the China Adhesives and Sealants Expo 2025. 

Polyimide adhesives find extensive applications across numerous high-end sectors including aerospace, electronics, and automotive manufacturing. These products not only deliver exceptional bonding performance and maintain stable adhesion under extreme conditions but also exhibit outstanding resistance to high temperatures and chemical corrosion. Available in various forms including molding compounds, films, foams, adhesives, and composite materials, they are extensively utilized in applications demanding high-temperature resistance, high strength, insulation, and lightweight properties. Polyimide molded plastics feature low density (approximately 1/5 that of steel), superior mechanical properties, and exceptional resistance to both high and low temperatures (capable of sustained operation from -240°C to 280°C, with peak temperatures exceeding 450°C). Additionally, they offer electrical insulation, self-lubrication, wear resistance, radiation resistance, and stable chemical properties, making them an ideal non-metallic material for harsh operating conditions. They find extensive applications in aerospace, naval vessels, microelectronics, printed circuit boards, and other fields. Examples include gaskets, vent valve seals, shims, bushings, bearing shells, electrical and thermal insulators, high-temperature insulating and heat-shielding components, coil formers, bearing retainers, and dynamic seals.

Through deep understanding of downstream markets and continuous R&D, the company continually optimizes the performance of polyimide molding compounds to meet the customized needs of customers across various sectors. In the electronics and electrical sector, polyimide molding compounds serve as high-performance encapsulation materials for electronic components, effectively shielding them from environmental impacts while enhancing product reliability and longevity. Within automotive manufacturing, these compounds are utilized in engine peripherals and transmission system components, maintaining stable performance under extreme conditions like high temperatures, pressures, and speeds, thereby ensuring vehicle safety. Simultaneously, the company actively expands the application of polyimide into emerging fields such as new energy and biomedicine. Through continuous innovation and technological breakthroughs, it is opening up broader market opportunities for polyimide materials.
