Cenospheres are
lightweight,inert,hollow,nonmetallic spherical materials,composed
largely ofsilica (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.Cenospheres also are utilized for
coating,paint and oil industry.Cenospheres not only can reduce the
weight of end products and cost but also increase the
strength.
Cenosphere
is widely used as filler material in various industries such
as Oil drilling industry, cement, rubber, plastics, resins,
concrete, lightweight construction prefabrications,
etc.Characteristics Lightweight, Free-flowing, Gray
or Off-white Color, Spherical, Inert, heat resistant and fire
proof;
