This High Strength Proppant is made from Bauxite and other special supplementary materials. HSP can not only reduce the requirements on hydrofracturing liquid, but can also improve the delivery performance in rock rift and increase the support profile of rock rift. It can result in satisfactory yield of oil/gas in the oil/gas well thanks to its excellent resistance to hydrofracturing. Avalaible in: 52MPa (7500psi),69MPa (10000psi),86MPa (12500psi) ,102Mpa (15000psi and 8/12mesh, 10/14mesh,[...]
