Recently, the small editor of Xinda Chemical, a white carbon black manufacturer, saw that the search index of the opening agent has increased. It must be that the demand for it has increased. The opening agent, also known as smooth agent, anti adhesion agent and anti caking agent, is commonly used in the production and preparation of plastic film products, which can effectively improve the opening performance of the film. So, what are its applications in plastics? Today, we'll tell you about it. Let's have a look.


In the production process of plastic film, static electricity will be generated due to the friction between the film and the equipment, resulting in too much friction in the curling process and affecting the brightness of the film. In the production process of plastic film products, in order to prevent the film products from sticking together and opening, it is necessary to add a smooth agent, also known as opening agent.


The editor of our white carbon black manufacturer ayota will tell you about the commonly used opening agents for plastic films:


The opening agents commonly used for plastic films were inorganic talc powder and diatomite, etc. in the early stage, organic oleic acid amide, erucic acid amide and EBS derivatives were developed in the middle stage; At present, synthetic silica is also widely used in thin films.


There are two main reasons for the problem of film adhesion. One is that after the film is closed, the vacuum tight state between the films is not easy to separate; Second, there are a large number of leaked molecular chains after the film is formed. After the two films are closed, the macromolecules are intertwined, making it difficult to open.


The inorganic opening agent is used to separate the membranes by making them uneven; The organic opening agent is to form a lubricating film on the surface of the film, reduce the friction coefficient of the film and make it not adhere to each other. Both hinder the entanglement of molecules.


The above is a brief introduction to the application of the opening agent in plastics. Do you all know it? It is also widely used and has high product value. If you need it, you can consult and buy it from the small editor of our white carbon black production plant ayota.
