Hydrophobic fumed silica Suppliers
hydrophilic fumed silica with a particular surface location of two hundred m2/g .The unique particle size can be 5- forty nm. It really is a type of higher purity white colloidal powder.
It is mostly utilized for large-temperature vulcanized silicone rubber, natural and organic silicone defoamer, sophisticated printing ink, powEPTcoating, PVC resin, unsaturated polyester resin thickening, thixotropic agent, pharmaceutical powder, tabular preparing, cosmetics and so on.
