Highly active microsilica electrical insulating materials

Highly active microsilica electrical insulating materials:This kind of silica fume is usually widely used in the field of electronic insulation.silicon micro-powder is used as epoxy resin insulation sealing filler for electrical insulation products, which can effectively reduce the linear expansion coefficient of the cured material and the shrinkage rate during the curing process, reduce the internal stress, and increase the mechanical strength of the insulating material, thus effectively improving and enhancing the mechanical and electrical properties of the insulating material.Therefore, the functional requirements of customers in this field for highly active micro silicon powder are more in terms of low linear expansion coefficient, high insulating property and high mechanical strength, while the requirements for its dielectric property and thermal conductivity are lower. The electric insulating material field usually selects a single specification of silicon micropowder with an ave…
