Liquid silicone rubber is a polymer elastic material with silicon oxygen bonds as the main chain structure. Its unique molecular structure endows it with excellent comprehensive properties, making it an indispensable innovative material in modern industry.
As a two-component liquid raw material, LSR forms a three-dimensional network structure through cross-linking reaction under the action of platinum catalyst, and finally solidifies into a solid form that combines inorganic material temperature resistance and organic material elasticity. This transition process from liquid to solid is not only flexible in technology, but also has given rise to its wide application in the field of precision manufacturing.
The most notable feature of LSR is its excellent physical and chemical stability. In the extreme temperature range of -60 β to 250 β, it can still maintain stable elastic modulus and mechanical strength, which makes it excellent in harsh environments such as automotive engine compartment seals and aerospace electronic component protective covers.
At the same time, its extremely low surface energy endows the material with excellent hydrophobicity and oleophobicity, which not only facilitates demolding, but also makes LSR products shine in hygiene sensitive fields such as medical catheters and baby pacifiers.
It is worth noting that the biocompatibility of LSR has passed international authoritative certifications such as FDA and ISO 10993, and can directly contact human tissues without causing rejection reactions, promoting the innovation of minimally invasive surgical instruments and implantable medical devices.
At the manufacturing process level, LSR has broken through the processing limitations of traditional rubber. Its low viscosity characteristics support the manufacturing of complex structures with micrometer level precision through liquid injection molding (LIM) process, and with the help of automated production lines, stable mass production of millions of orders can be achieved.
This technological innovation not only shortens the molding cycle to tens of seconds, but also completely eliminates the volatile substances produced by traditional rubber vulcanization through closed mold molding technology, which meets the dual needs of modern manufacturing for clean production and efficiency improvement. In typical automotive electronic applications, LSR encapsulation technology can integrate metal sensors with flexible seals, significantly improving the waterproof and dustproof level of the product.
The progress of materials science continues to expand the application boundaries of LSR. Through nanofiller modification technology, researchers have developed composite LSRs with special functions such as conductivity, thermal conductivity, and fluorescence. In the field of wearable devices, conductive LSR is used to manufacture flexible electrodes for high-precision acquisition of human physiological signals; In the field of 5G communication, thermal conductive LSR has become a key material for solving chip heat dissipation problems.
What is even more remarkable is that LSR's environmental attributes are leading a new trend in material development - its production process is free of toxic by-products, and waste products can be fully recycled and reused, meeting the sustainable development requirements under the global carbon neutrality goal.
With the integration of intelligent manufacturing and IoT technology, LSR is evolving from a single material to an intelligent carrier. By embedding microsensors or shape memory units in materials, LSR products can achieve environmental response and autonomous adjustment functions.
This breakthrough in material intelligence has opened up new possibilities for cutting-edge fields such as soft robots and intelligent medical implants. It can be foreseen that liquid silicone rubber, which combines functionality and adaptability, will continue to play a leading role in material innovation in future industrial transformation.
