1.Derformance
High transparent zinc oxide is soda ash type zinc carbonate mate rials for production of special products，products are more likely to spread out．this zinc oxide have a lower refractive index high transpa rent zinc oxide is suitable for rubber products
2.Usage
Used as the reinforcing filte r of tight color．is also ve ry strong activator Apply to high elastic demand ortransparent rubber，used for hot air or sulfamide vulcanization rubber，metal oxide and the sulphur vulcanized rubber，used as a light astringent，high transparent zinc oxide is suitable fo r
