　　Analysis of the causes of color migration of TPE plug material.

　　Color migration

　　Small molecule material migration

　　TPE, TPR products in the modification process, sometimes add some small molecular weight additives, but this kind of additives and the base material compatibility is poor, the general additive amount of 2 ~ 3 ‰. If the amount added is too much, it will lead to small molecule substances will be extended with time, and migration occurs.

　　The reason for migration is TPE, TPR in the mixing modification, the temperature is higher, additives in the mixing system can be better compatible (more soluble). When the mixing modification is completed, the temperature is reduced to room temperature, the amount of additives dissolved in the modification system will be reduced. With the passage of time, these small molecules will gradually migrate to the surface of TPE, TPR products.

　　If the three colors with the same material, the color powder with the oil small molecules migrate together.

　　Find the reason, naturally find how to solve the problem of TPE plug material color migration.
