摘要
A lubricating system composition for the extrusion of polyvinyl chloride resin conduits is provided by treating silica fume particles at least in part with a lubricant to form a premix additive for polyvinyl chloride extrusion compounds whereby the resulting product has unique and particularly advantageous physical characteristics which makes possible the reduction in wall thickness and an increase in loading of calcium carbonate to effect a material reduction in cost of manufacture.
