Liquid silicone rubber is a liquid form of linear polysiloxane based polymer, which is cured through platinum catalyzed addition or organotin catalyzed condensation reactions, forming an elastic material that combines the convenience of liquid processing with the excellent properties of solid silicone rubber.
Its liquid characteristics give significant advantages to the machining process - low viscosity fluids can be filled into micro scale mold cavities through precision injection systems, achieving zero flash forming of complex structures such as 0.1mm films and micro gears; Dynamic vulcanization technology allows the material fluidity to be adjusted during the curing process to meet the rapid filling requirements of multi cavity molds.
In terms of performance, its temperature resistance range breaks through the limitations of traditional rubber, maintaining elastic stability in the range of -70 ℃ to 350 ℃, with a UV aging resistance time of over 3000 hours, and a Shore hardness range from 5A (similar to jelly) to 70A (close to rubber tires). Combined with filler modification, it can achieve customized performance with a thermal conductivity coefficient of 0.8-2.0W/(m · K) and a volume resistivity of 10 ¹⁴ -10 ¹Ω· cm.
In the medical field, medical grade products that comply with ISO10993 biocompatibility standards have achieved implant level applications, such as the insulation layer of pacemaker leads that can withstand 1 billion bending cycles; In the field of electronics, the stability of its dielectric constant of 2.8-3.2 has been utilized as a key material for the sealing ring of 5G base station filters and high-precision sensor packaging.
With the development of nanocomposite technology, the tensile strength of liquid silicone rubber modified with gas-phase silica has exceeded 15MPa. Combined with 3D printing technology, precise manufacturing of three-dimensional mesh structures can be achieved, demonstrating unique value in fields such as flexible electronic skin and wearable medical devices.
