The application of silica in liquid silicone rubber

Thread Content

Adding silica to liquid silicone rubber significantly improves its tensile strength, tear resistance, and wear resistance, as well as enabling it to achieve a very high level of transparency. After modification, the strength of silicone rubber increases by dozens of times; it performs well in controlling the rheology and thixotropy of silicone rubber cured at room temperature, as well as serving as an additive for preventing sedimentation, thickening, and sagging. Traditional silica gel tends to thicken over time during use, allowing only limited amounts to be added, which results in an insufficient enhancement of its performance. Crown flag silica features high dispersion, high addition capacity, and good flow properties, effectively solving the problems of thickening and post-thickening; it is widely used in applications such as thixotropic agents, reinforcing agents, and lubricants in silicone rubber.
