Two main purposes

It can be widely used in fracturing proppant fracturing deep, high-pressure oil and gas layers. High quality bauxite, the main raw  material crushing finely ground into powder resin coated frac sand after, with various additives, repeatedly mixing, granulating, polishing. High temperature sintering, the product has a high compressive strength, low density, good sphericity, finish high conductivity and strong advantages. By the China Research Institute of Petroleum Exploration and Development high density ceramic Langfang Branch support evaluation laboratory testing, the performance indicators fully meet SY / T5108-2006, SY / T6302-1997 standard, currently in the lead.
