Pesticide grade silica: silica with strong water and oil absorption properties, it can play a role as drug delivery in suspending and wettable powder of pasticide.Our products include:white carbon blacksilica flatting agentfood grade silicon dioxidefumed silica,etc.white carbon black with for high grade rubber / tyre / soles / pesticide / feedstuff additive industry silicon dioxideSpecifications1.Precipitated white carbon black(SiO2) 2.powder and granular 3.Powder, granular 4.ISO certificatePrecipitated white carbon black(SiO2) 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.
