Generally powder PbO hard to evenly dispersed under the normal temperature which cause activity of vulcanizing decreased and vulcanized rubber's static mechanical property and dynamic fatigue decline. Our pre dispersed PbO-80 master batch due to its selected grain size and made pre diffusing in ethylene propylene rubber and with Surfactants and dispersants so it can be fed in mixing process quickly to make dispersion evenly and perfect activity. What's more, PbO master batch is in granule shape to avoid blocking.

Technology
Pre-dispersed PbO-80 master batch is a kind of special lead oxide that used in rubber industry. Its combined elastomer could be avoid absorb moisture from air. Because of pre-diffusing evenly before feeding, Using our PbO-80 master batch makes extrusion rubber products surface more smooth than using powder lead oxide. Meantime, your produces tensile strength increased and elongation improved.

Application and Dosage
Most rubber product. To improve its static and dynamic mechanical property.

Dosage: 3-8 phr
