Application
ZC-185MP is a high dispersion, high purity precipitated silica. It
can significantly improve the wear resistance of the rubber
compound, resistant to flexion performance, heating oxidation,
instead of a large number of carbon black for high-performance
tires, which can effectively reduce tire rolling resistance and
reduce fuel dosage and improve the wet skid resistance and safety
performance.
Also use in tyre industry ,PCR tire Semi-steel radial tyre,
all-steel radial tyre, TBR tire ,BTR tire steel cord ,meridian
tyre,Bias tyre etc
