Liquid silicone rubber has demonstrated extensive application value in the medical and electronic fields due to its biocompatibility and high-performance characteristics. In the field of healthcare, it is used as a biocompatible material for disposable devices such as syringe seals and urinary catheters, implantable medical devices such as breast implants, ear stents, and drug delivery carriers. Its sterilization resistance characteristics, such as ethylene oxide, steam sterilization, and low cytotoxicity, meet the strict ISO 10993 standard and are suitable for precision scenarios such as surgical robot seals and dialyzer membrane components.

In the field of electronics and electrical engineering, it is used for chip encapsulation, 5G base station antenna sealing, high-voltage cable accessories and other scenarios, using high and low temperature impact resistance, moisture-proof insulation characteristics to protect electronic components. For example, transparent silicone encapsulated IC chips can achieve visual fault detection, and the sealing strip of the power battery pack needs to meet the requirements of flame retardancy and electrolyte corrosion resistance. By combining microelectromechanical system packaging and 3D printing technology, it achieves precise molding of sensors and microfluidic chips, promoting the development of flexible electronics and wearable devices.

With the advancement of technology and the upgrading of market demand, liquid silicone rubber is evolving towards high-performance, green, and intelligent directions. In terms of technological innovation, additive liquid silicone rubber achieves by-product free curing through platinum catalyzed crosslinking, improving material purity and performance stability; Condensed liquid silicone rubber improves dimensional accuracy and weather resistance by optimizing catalysts and fillers. Functional modifications such as conductivity, heat conduction, and flame retardancy expand their applications in high-end scenarios such as new energy and aerospace.

In emerging applications, lithium battery soft pack sealing and hydrogen fuel cell electrode plate coating in the field of new energy need to be resistant to hydrogen permeation and chemical corrosion; Biomedical frontiers focus on biodegradable liquid silicone rubber for tissue engineering scaffolds and flexible joints in minimally invasive surgical robots. In terms of intelligent integration, smart seals combined with sensors such as pressure sensing automotive seals have become a research and development hotspot. In terms of greening and sustainable development, under the promotion of environmental policies, the industry prioritizes the use of recyclable materials and low-energy production processes to reduce VOC emissions. Under the circular economy model, waste recycling technology is gradually maturing, promoting the transformation of the industrial chain towards low-carbon. In the future, liquid silicone rubber will rely on technological innovation and cross disciplinary integration to continuously unleash growth potential in strategic areas such as high-end manufacturing, biomedicine, and new energy.
