Has a good dynamic performance of zinc-containing additive-free natural rubber

Due to the low efficiency of Lian plastic machinery, so people began to widely used plastic chemical agent solution. Despite its small amount (for example, 0.1 to 0.2), but it was very effective in reducing viscosity. However, they often have a number of short-chain material, leading to rubber dynamic performance of the poor, as well as the sticky rubber roller. In recent years, mixing methods have changed, no longer has the use of all plastic agent solution. Through the use of auxiliary agents to promote catalysis, in 120. C above the temperature of most any plastic solution, this time to become a leading chain oxidation. Usually the time, has joined the filler, the promoter will be assisted passive. In order to explain these issues, some of the literature presents a natural rubber to reduce the viscosity of the new theory. There is a new material (such as the HT 105) to avoid plastic chemical agent solution to the above-mentioned drawbacks, but the substance remains the zinc. In view of the European Union is about to impose restrictions on zinc, Karl Ment-ing and others to develop a new type of zinc-free plastic agent solution (XP1440).
