Raw rubber.
Natural Rubber, which is obtained predominantly from the rubber tree, Hevea Brasiliensis, is an aqueous colloid of rubber containing 30-40% rubber, by mass. Getting the rubber in a dry form is a specialized process in itself. The raw is concentrated, i.e., its % rubber content is increased and proportion of non-rubber constituents is reduced by processes such as centrifuging and creaming.

Properties: It is yellow to brown schistose or granular solid, synthesized by formaldehyde, modifying agent, active agent and parasubstituted alkylphenols which have different number of carbon atom in the alkyl groups. Applications:The super tackifying resin has the characteristics of long-term effective, nice moisture stability and high viscosity-promoting ability. It's viscosity-promoting ability is similar to para-tertbutylphenolaceylene resin and superior to para-tert-butylphenol(or para-tert-octylphenol) formaldehyde resin. This product should be added under the temperature higher than it's softening point in the early period of mixing, to ensure the resinf+s homodisperse and to get the best viscosity-promoting effectiveness. It can save the use level of processing oil to a certain degree. The recommended dosage is 2-5 phr. Storage: Kept in dry and ventilating place, protected from heat and fire, the storage life is 18 months. The products that exceed storage life and qualified can be used. Package: Packed in knitted bags lined with a layer of kcraft paper bag and a layer of plastic bag. The netweight is 25kg per bag.

Rubber mixing mills manufactured by our company have the models xk-160-xk-550(560), and we also manufacture refiner and gel breaker;classified by the perspectives of product standard and technical progress, the open mills manufactured by our company are coexisting with three generations of products: The traditional models of national reserved standards, that is, single output axis, which is driven by big and small gears and the differential motion of front and rear rollers are realized by speed ratio gears. National latest standards, that is, the output of reducer is double-axis output, and the roller is directly coupled by the universal coupled by the universal coupling. As for the double-axis output models have the disadvantages of high costs, we have developed the single-axis output open mills with a relatively lower cost, and such a model is an exclusive model of our company and is favored by the consumers
