HOLLOW GLASS MICROSPHERES
                             
1.Product Description and Application
Hollow glass microsphere is a kind of ultra-lightweight inorganic non-metallic material with hollow structure,and it is a versatile and high-performance new lightweight material developed in recent years. It will be the new composite materials at twenty-first century. Its true density is 0.20-0.60g/cm3 with 2-150μm in diameter. It owns features with light weight,large bulky, low thermal conductivity,high compressive strength,smoothly mobility etc.It can be used in paint and coatings,rubber,plastics,FRP, artificial stone, putty and other products as filler and weight-reducing agent.Because of its high compressive properties,it can be used to produce high-strength,low-density cement slurry and low-density drilling fluid in oil and gas extraction industry.
Applications:Its applications are in the fields of thermal insulation coating,putty,plastic casting polyester,FRP,SMC(BMC),radome,synthetic foam, adhesives, printed circuit board substrate, RTM, bowling, fan blades, & caulking materials, emulsion explosives,sealant,pipeline insulation materials, artificial marble, PVC, low density oil drilling, light cement, and other deep-sea buoy etc.
