General Silicones Highlights Advanced Heterogeneous Bonding Technology in Rubber World Magazine

Hsinchu, Taiwan,– July 28, 2025 – General Silicones Co., Ltd. (GS),  a leading innovator in silicone rubber solutions, today announced the publication of a comprehensive article in the June 2025 issue of Rubber World magazine, Volume 272, Number 3. The article, titled “Heterogeneous bonding technology for silicone rubber,” highlights the company’s significant advancements in overcoming the long-standing challenge of effectively bonding silicone rubber to a diverse range of materials.

 

 

Silicone rubber, known for its exceptional properties such as superior temperature resistance, chemical inertness, UV resistance, electrical insulation, biocompatibility, and remarkable flexibility, has become an indispensable material across numerous industries. However, its inherent low surface energy and high chemical stability lead to poor bonding with other substrates, limiting the broader application of using silicone rubber in multi-material assemblies.

 

General Silicones has dedicated extensive research and development efforts to address this critical industry need, resulting in groundbreaking technological solutions. The newly published article elaborates on these innovations, detailing how General Silicones has successfully developed robust bonding methods for silicone rubber with an impressive array of materials. These include various metals such as iron, aluminum, and stainless steel; a wide range of plastics including PET, PI, PC, PU, ABS, and PTFE (Teflon); and other complex substrates like fiberglass and textile fabrics. The article meticulously outlines the advanced techniques and surface treatments employed, such as specialized surface primers, chemical surface treatments, environmentally safer plasma surface modification, and precise functional group integration, all contributing to these significant advancements.

Beyond the innovative bonding methodologies, the Rubber World article also highlights General Silicones’ rigorous adhesion testing protocols. These include high-temperature and high-pressure durability tests, precise direct tensile tests, and demanding boiling water shock tests.

Designed to ensure reliable and long-term adhesion performance, these internal testing methods are particularly critical for applications in highly demanding sectors such as automotive and medical. This commitment to stringent testing reflects General Silicones’ dedication to delivering silicone assemblies that maintain their integrity and performance, even under extreme operating conditions.
