CHEMICAL DESCRIPTION: Precipitated Silica powder / granular
TYPE: Richon-180
GENERAL DESCRIPTION: Precipitated silica with special physic-chemical properties, work as reinforcing transparent fillers highly valued in formulation of rubber-based blends. In particular, They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost.
APPLICATION: Light-colored, color and High-grade transparent rubber products.
