active silica powder

Our active silica powder is made of high purity quartz rock,processed under first class equiment and advanced quality control .

ActiveSilica Powder

Active Silica Powder Crystalline silica is in the Powder adopted on the basis of the unique materials used silane, silica Powder particles on the surface modification,To change the original surface of the material,Effective resin and silica Powder enhance the cohesive force and had water interface performance,Curing product thereby increasing the mechanical strength,Modulus of elasticity, heat aging properties, resistance to climate,More valuable is to greatly improve the local high-voltage electromechanical products free discharge phenomenon. Activity Silica Powder with resin, curing agent crosslinking reaction,But it will not block the promotion and resin, curing agent of the curing reaction,Activity Silica Powder been widely used high-pressure casting electrical, electronic packaging materials industries.
