Isolation agent, as the name implies, is an additive that plays the role of isolation, which is different in different fields. It is a kind of operational assistant, such as film separator in rubber processing,

Main role

It is used to prevent the film or semi-finished product from bonding with each other. It is often used in the plastic mixing, tablet pressing and molding of raw rubber and rubber. In other aspects, such as the demoulding of concrete components, the annealing of laminated steel sheets, etc., separators with similar functions will also be used. In addition, there are so-called UV isolators in the cosmetics industry.

Film separator:

       In the process of rubber processing, due to its unique self viscosity, it brings a lot of inconvenience to large-scale industrial production, especially to the handling and reprocessing of rubber mixture and plastic compound. In order to reduce the trouble, rubber product manufacturers often apply a layer of isolating agent on the corresponding film before the final product of the rubber mixture is made, such as before the transportation and storage of the rubber mixture, before the extrusion, extrusion and hot mixing, so as to prevent the film from adhering to each other.

      The function mechanism of the isolating agent: it is to use the large difference between the mutual solubility of the isolating agent itself and the rubber, when the rubber film is coated with the isolating agent, a thin isolating layer is formed between the rubber films, to block or slow down the mutual adhesion between the films, so as to facilitate the process operation.

The material used as rubber film separator must meet the following requirements:

1. The solubility coefficient should be different from that of rubber;

2. High safety, non-toxic, no harm to human health and no pollution to the environment;

3. It can form isolation layer on the surface of rubber film, so as to have good isolation effect;

4. It has little negative effect on physical and mechanical properties of rubber products;

5. Convenient process operation;

6. Low cost.

UV barrier:

One is UV absorber, the other is UV isolation agent. UV absorbers absorb UV light through chemical reactions. This kind of UV absorber is usually highly sensitized and is not suitable for large-scale use. UV isolators are relatively safe and not easy to cause allergies, but they are usually greasy and airtight. Moreover, due to the large particles, they are easy to block pores, so after use, make-up removers must be used before they can be completely removed
