Cenosphere - Lightweight Non-metallic Refractory Material | High Compressive Strength, Inert And Thermal Stable

These Cenosphere is a kind of non-metallic multi-function lightweight refractory, is metallurgy, petroleum, chemical, electrical, mechanical and other industries of the latest development of flame retardant, absolute refractory material. Widely used in light, intermediate heat preservation material products, casting industry cap mouth products; The cementing cement reducing agent is designed for oil well cementing and the development of a new product production, with a light specific gravity, high compressive strength, etc.
Cenosphere are lightweight,inert,hollow,nonmetallic spherical materials,composed largely of silica (SiO2) and alumna (Al2O3).They have good flowability,ultra low density,nonpoisonous,corrosion-resisting,thermal stable,high partial strength,good insulating,sound isolating,low water absorption,low thermal conductivity that are extensively used in the rubber, equipment of glass fiber reinforced plastic, polyester,plastic as filler.
