To minimize the loss of quality, we recommend a maximum storage temperature (TS max.) for each organic peroxide product. For DMDBH TS max.= 30 ípC When stored under the recommended storage conditions, DMDBH will remain within the specifications for peroxide of at least 6 months after delivery. Thermal stability Organic peroxide are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test. Organic peroxide are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT).

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.

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
