Use Characteristics
ZnO**0 is a special grade of zinc oxide particularly suitable for the rubber industry. Due to its EPDM elastomer bound form, the absorption of humidity from the atmosphere during storage is prevented. In comparison to extrusion compounds containing powdered zinc oxide, those with ZnO**0 provide smoother profiles. This is due to the more homogeneous dispersion of ZnO**0. A slight increase in modulus and tensile strenghth usually occurs; elongation at break is also improved. ZnO**0 prevents the heat swell which normally occurs when powdered zinc oxide is used in CR mixes.
1. ZnO**0 is used as rubber accelerator of vulcanization upon sulfur curing system. It not only acts as activator to sulfur curing system, meanwhile as a cross-linking agent to Chloroprene, Halogenated isobutylene-isoprene rubber(HIIR), Carboxylated nitrile rubber(XNBR), and Carboxylated styrene-butadiene rubber(XSBR).
2. ZnO**0 shows very good dispersion especially to low hard of low mooney compounds. It acts as both heat conductive feller and white pigment too.
3. ZnO**0 significantly reduces decomposition temperature of ADCA blowing agent in EVA foam products. It is easier for weighing, storage and delivery will be better.
 
Processing Advantages
The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easy quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective ZnO is assured.
