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.
