high refractory cenosphere microspheres for oil drilling
What is the Ceramic Hollow Microspheres ?
u Ceramic Hollow Microspheress are hollow ceramic microspheres found in fly ash, a natural by-product of coal combustion during the generation of electric power.
u Refractoriness of Ceramic Hollow Microspheres is 1610 degree celsius, it’s a excellent light weight insulation thermal refractory material.
u Because of small, light weight, hollow, hight strength, Ceramic Hollow Microspheres are widely used as fillers or functional extenders in the manufacture of plastics, paints, resins etc.
u Cenospheres also provide the advantage of significantly improved flow and workability which are all desirable in a range of applications, such as: Oilwell Cementing, Refractories.
u Cenospheres also provide the advantage of significantly improved flow and workability which are all desirable in a range of applications, such as: Oilwell Cementing, Refractories & Foundries, Cementitious Construction Products, Joint-Compounds, Bitumen Sound-Dampening, Adhesives, and many more.
