  The Casting film test line for the Polish customer has been shipped from the warehouse today.

  POTOP will participate in the upcoming Orlando Plastic and Rubber Industry Exhibition (NPE) in the United States, and will provide you with efficient intelligent polymer experimental analytical instrument solutions!

OPP film is a kind of polypropylene film, because the production process is multi-layer extrusion, it is called co-extrusion oriented polypropylene film (OPP).

    Mixing means that in order to improve the physical and mechanical properties of rubber products, improve the processing and molding process, reduce production costs, it is necessary to add various adjuvants in raw rubber or plastic glue, such as fillers, reinforcing agents, accelerators, vulcanizing agents, antioxidants, anti-scorching agents, etc. These adjuvants have solid, liquid and other materials, and the various adjuvants added are dispersed evenly. Make sure the properties of the compound are consistent. Therefore, the process of evenly dispersing various compounding agents to raw rubber or plastic rubber in the rubber mixing machine is called mixing, and the rubber produced by mixing is called mixing rubber.
