Product name:White carbon black |
Chemical name: Silica, precipitated, hydrated;
Molecular formula: SiO2 · nH2O;
Appearance: white granules or powder
Use:
- Used for [medicine, feedstuff]: Silica for medicine use is white granular powder with high
purity, high fluidity, water absorption and flowage promotion,
mainly used as auxiliary medicine materials and feedstuff
additive.
- Used for [silicon rubber]: For its
special physical and chemical properties, it is the best
transparent reinforcement additive in rubber-based blends. It can
greatly improve the aging resistance, resilience and compressive
deformation resistance of silicon rubber.
- Used for [tyres]: If used in
thread, it can greatly reduce the rolling resistance f tyres, and
strengthen the holding power of types on wet or icy ground.
- Used for [soles]: It is reinforcing
filler for rubber soles with high reinforcing effect as that of
carbon black, and it can make rubber products with light color or
transmissivity.
- Used for [food]: It is white fine
powder with high purity, high fluidity and large specific surface
area, mainly used as food anti-caking agent, antioxidant,
thickener, coagulant, suspending agent, carrier of aromatical
chemicals and active components, quality improver and oil
absorber, etc.
