Application: Zinc oxide can function as curative activity in sulfurization system of natural rubber and synthetic rubber. It is usually used in combination with zinc stearate, especially has good effects to buty1 rubber and halogenated buty1 rubber. General zinc oxide powders, are easy to absorb the moisture and agglomerate during storing or mixing material. Thereby causing asymmetry dispersing and the heterogeneous vulcanization degree of rubber products. Meanwhile, it is also easy to bring dust so that to affect the accuracy when weighting zinc oxide. To buty1 rubber, zinc oxide undispersed will great decrease the products useful life, such as sulfur gelatine capsule. To halogenated buty1 rubber, zinc oxide powders are hard to disperse, such as in the inner liner of radial ply tyre or buty1 inner tubes, during calendaring and extrusion, easily appear the phenomenons of agglomerates, scorching particles, hard spots in rubber surface which have a serious effect on the anti-air permeability of buty1 goods.HSZ is produced with import superfine zinc oxide which has high purity and high specificarea,after special treatment, add in special rubber and dispersing agent.Thisproduct has many advantages such as anti-water absorption,anti-scorching, easyto disperse,weigh and good compatibility,etc.HSZ is widely used in rubber industrial products,such as halogenated buty1 innerliners of radial ply tyre,buty1 inner rubes,CR industrial products and shoes. Dosage: Recommend dosage:0.5-2.0PHR Package and Storage:1. Package: paper boxes, 25kg/box2. Sealed storage: Stored in dry place at room temperature. Avoid sunlight.
