Looking back at the development journey of liquid silicone rubber (LSR), it has evolved from a basic single-purpose sealing and damping material into a multifunctional composite capable of thermal conductivity, electrical conductivity, high optical transparency, self-healing, and ceramifiable fire protection. Behind this technological leap lies the continuous expansion of material performance boundaries driven by emerging downstream industries, as well as a vivid microcosm of the silicon-based new materials sector's transition toward high-quality development.

Currently, multiple frontier tracks are presenting unprecedented opportunities for LSR. In the new energy vehicle sector, with the proliferation of 800V high-voltage platforms, battery systems demand higher levels of thermal management and passive safety. Potting and sealing compounds featuring high thermal conductivity, low volatility, and ceramifiable fire-retardant properties have become key to preventing thermal runaway and ensuring overall vehicle safety. In the consumer electronics and AI server sectors, facing surging chip power densities, ultra-thin, highly thermally conductive liquid silicones are emerging as core solutions for efficient thermal management. Furthermore, in emerging fields such as humanoid robotics and low-altitude economy (eVTOL) vehicles, specialty silicones combining biomimetic tactile feel, high tear strength, and extreme environmental tolerance are providing foundational support for lightweighting and high reliability of intelligent equipment.

Alongside the pursuit of high performance, green and sustainable development has become an irreversible industry trend. The R&D of bio-based silicone monomers, the widespread adoption of halogen-free flame-retardant formulations, and the recycling and reuse technologies for waste silicone rubber are gradually transitioning from laboratories to industrialization. This not only responds to the global call for carbon neutrality but also builds new core competencies for enterprises.

From basic sealing to intelligent thermal management, the technological evolution of LSR knows no bounds. In the face of the vast opportunities presented by the era of intelligent manufacturing and green mobility, upstream and downstream players across the industry chain must strengthen collaborative innovation—rooted in materials science and continuously pushing performance limits—to collectively forge a path toward high-quality development for the silicone rubber industry.
