epoxy molding compound cristobalite price casting powder 200
casting powder mold
Cristobalite silica powder is nature quartz by temperature control
(600-1447 degrees C)is calcined into the quartz,the quality
grading,grinding,purfication,powder grading become cristobalite
silica powder,the crystal phase to tetragonal,with quartz
consistently excellent electrical properties,and
thewhiteness,brightness high ,density of small,relatively low
hardness of quartz crystal,refractive index is very close to most
of resin properties,so the high-grade coating,wood
coating,adhesives,rubber and plastic areas have excellent
performance,especially as applied to fill the grain weight of
rubber reduce the level of transparency and other properties of
system,used in wood coating and adhesive system on the final
product transparency also had an outstanding performanca ;the
quartz holding rate is high,hot drum coefficient of 54*10 K.

Compared with the silica powder and silica sand produced by
traditional process, ours of natural quartz has many advantages,
such as high purity, white, high silicon content, low impurity
content, less variegated particles and low lead content. Our
product has excellent insulation resistance, arc resistance and
flame resistance. It is widely used for casting, pouring and
molding in high and low voltage electrical epoxy, high voltage
power transmission systems, electronic components, large-scale
integrated circuits, equipment manufacturing and other industries.
It is the ideal environmental friendly insulation material and
filler in quartz plates, fine ceramic manufacture. Also widely used
in high-end anti-corrosion paint, silicone rubber, various
adhesives and other industries.
With many resource advantages as local quartz ore storage capacity,
high purity and easy exploitation, through domestic counterparts
pioneered multi-level material crushing, grading, cleaning,
removing iron, screening and purification by fully automated
micro-manage production processing equipment, we produce 20,000
tons various kinds of refined sand, 5,000 tons various models
multipurpose micro silica powder and 30,000 tons super white,
ultra-thin special glass sand annually.
