Product Description Please kindly note that we are the manufacturer of this product, not traders or any kind of distributors!1. DescriptionHollow Glass Microspheres (also known as Glass Bubbles) are hollow glass spheres made of chemically stable Soda-lime-borosilicate glass with thin walls (wall thickness 1~3.5μm), which are available in a range of strengths and densities and offer excellent consistency from batch to batch. Sinosteel Y series Hollow Glass Microspheres are engineered for greater survivability under demanding downhole conditions and widely used by well drilling & cementing companies all over the world.Drilling/completion/work-over fluids formulated with Hollow Glass Microspheres:? Successfully and predictably reduce the fluid density? More homogeneous and incompressible fluid properties compared to aerated systems? Eliminate the need for specialized equipment used in foamed or aerated systems? More economical and allow a greater density reduction window than synthetic oils? Compatible with both water based and oil based systems? Resistant to harsh downhole conditionsCementing slurries formulated with Hollow Glass Microspheres:? Best density reduction capacity? Lowest effective density at any pressure? Help prevent problems associated with lost circulation, including reduced top-of-cement (TOC) and formation damage/reduced well productivity? Help achieve highest strength-to-weight cement designs? Increased yield per sack of cement 2,True Density Product Typical (g/cm3)True Density (g/cm3)MinimumMaximumY55000.380.360.40Y40000.400.380.42Y60000.460.440.48Y8000S0.420.400.44Y120000.600.570.63Y150000.630.600.66Y180000.630.600.663.
