Predispersed Rubber Chemical ZnO-80

Predispersed Rubber Chemical ZnO-80: Curing activator, particularly in the presence of fatty acids for almost kinds of rubbers

Product description:

Composition	80%Finely selected zinc oxide, 20EPDM/EVA binder and dispersing agents
Appearance	White to grizzly granules
Density, 20°c	~2.98g/cm3(20°c) Approx.~2.98g//cm3

Use Characteristics :Predispersion ZnO-80 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 predispersion ZnO-80 provide smoother profiles. This is due to the more homogeneous dispersion of predispersion ZnO-80. A slight increase in modulus and tensile strenghth usually occurs; elongation at break is also improved. Predispersion ZnO-80 prevents the heat swell which normally occurs when powdered zinc oxide is used in CR mixes

Processing Advantages :The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective ZnO is assured.

Dosage levels :3 - 8 phr

Applications: Curing activator, particulary in the presence of fatty acids for almost kinds of rubbers.

Storage stability :In original closed containers under cool and dry
