Many zinc oxide production company, can't solve the problem of the zinc oxide dispersion, Qingdao TOPSEN chemical CR510 antioxidant activity, dispersion effect is good.
Zinc oxide and evil people mixed up the products on the market, the price is chaotic, the higher the purity of the more expensive.
Even some manufacturers selling price is lower than the zinc ingot, zinc oxide, actually the price of zinc oxide is transparent, the zinc ingot prices by 80%, plus the processing fee, then you can come out the price of zinc oxide!
But individual manufacturer is lower than the price of zinc ingot, it is adulterated, usually in zinc oxide mixed with calcium carbonate, light calcium or coarse whiting.
Thus skimping might make the product quality drops greatly!
CR510 is a good rubber surfactant, containing zinc oxide, but zinc content is only 50%, in line with the eu environmental requirements, and solved the problem of serious pollution in zinc oxide processing now, CR510 can perfectly instead of zinc oxide, has good dispersion in NR.
