It plays an important role in plastics. Anti-blocking agents can reduce the adhesion phenomenon between plastic films and improve the processing performance and ease of use of plastic products. During the plastic processing and storage process, due to the characteristics of the plastic surface, the films are easily adhered to each other, which will bring many inconveniences to production and use. The addition of Silica ec 700 anti-blocking agent can form tiny protrusions on the plastic surface, reduce the contact area between the films, and thus reduce the occurrence of adhesion. This anti-blocking agent is usually added to plastics in powder form and plays a role by being evenly dispersed in the plastic matrix. It can improve the smoothness of plastics, making plastic films easier to unfold and transport during processing, reducing friction and wear. In addition, anti-blocking agents can also improve the optical properties of plastics, reduce the haze on the film surface, and improve transparency. In some high-end plastic applications, such as food packaging, optical film and other fields, the optical properties of plastics are required to be high. The use of Silica ec 700 anti-blocking agent can meet these needs. At the same time, anti-blocking agents can also improve the printing performance of plastics, making ink easier to adhere to the plastic surface and improving printing quality.
