Leading Products

Holywell Hollow Glass Microspheres (HGMs) are a kind of hollow spherical powdered ultralight inorganic nonmetallic materials. Its true density is 0.15-0.60g/cm³, the particle size is 2-130μm, the wall thickness is 1-2μm and the compressive strength resistance is 300-18000psi. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties.
Due to its excellent advantages of light weight, lower thermal conductivity, higher compressive strength resistance, high temperature resistance, chemical stability and good fluidity, now it is widely used in the fields of low density drilling fluids, Super-high compressive strength cementing slurry and Super-low density slurry etc.
Our HGMs can offer greater survivability under many demanding processing conditions. Now we can supply variety of sizes and grades of HGMs to meet your product and processing requirements.
