It is very hot in summer, and TPE and TPE plastics will agglomerate. How to solve it?

friends who are engaged in plastic granulation, especially soft plastic granulation, know that in hot summer, soft raw materials such as TPE and TPR and their products are seriously stuck and caked. Such as TPE, its raw material degree is relatively low, because its auxiliary is mainly oil, so it will appear caking phenomenon.

The reasons for the caking of soft plastics such as p>TPE and TPR are as follows: First, the oil-filled ratio is high. Sometimes, in order to produce ultra-soft and hard products, it is necessary to have enough oil in the SEBS/SBS mixing system, but the oil itself is viscous. The greater the oil ratio, the greater the possibility of its precipitation (oil spitting), which leads to the caking of transparent particles. Second, the particles are not sufficiently cooled, the temperature is high, and the viscosity of oil in the mixing system is high, resulting in particle adhesion, so the problem of agglomeration is more likely to occur in summer when the temperature is high.

solution to caking: firstly, it should be cooled enough after granulation, and it is suggested that the surface temperature of particles should be below 3℃ before packaging; The second is to add functional additives-"Shuangxiao plastic anti-caking agent" or "Shuangxiao plastic anti-sticking agent". The additive does not contain oily substances, which can weaken the surface viscosity between particles and enhance the smoothness of particle surfaces, especially for TPE/TPR transparent materials with super soft hardness. You can also trust me privately for detailed technology, and I will provide technical services. Another is to add cooling water or ice cubes. As it is difficult to cool in summer, and the production process is less than one hour, the water temperature will continue to rise, which will cause the particles to agglomerate and adhere when they meet hot water when they leave the die. Ice cubes can be added into the water inlet pool to continuously cool the water in the pool, which can also alleviate the phenomenon of plastic agglomeration and adhesion.
