PE, PP, EPDM, PTFE, these common industrial plastics surfaces can be relatively low, presenting a non-polar state, not easy to fully wet affecting paints, printing inks or adhesion; some organics and metals also require particularly expensive glues to improve adhesion properties.

As a carrier of plasma surface technology, vacuum (low-pressure) plasma cleaner can be simple and effective to obtain the activation or chemical modification of polymer surfaces. In many industrial applications, this method proves polymer processing properties (adhesion, printing, painting, etc.).

Plasma cleaner vacuum (low pressure)

In order to achieve adhesion between non-polar plastics and surfaces such as adhesives, paints, coatings, etc., polar groups must be formed on the surface.

In addition, covalent chemical bonds between the substrate and the adhesive or coating indicate particularly good adhesive properties. In this case, the adhesive only breaks under high mechanical loads and does not break at the interface.

Polar functional groups can be integrated into the plastic surface by plasma surface treatment techniques, depending on the gas applied in the vacuum (low pressure) plasma cleaner, including hydroxyl groups, also known as hydroxyl groups (-OH) or amino groups (-NH2) The effect of the plasma treatment is confined to the surface of the material, the polymer material itself is not affected.

The plasma generated by the vacuum (low pressure) plasma cleaner has activating properties that increase the surface tension, allowing the formation of acute groups between oxygen functional groups and molecules on the surface of these materials, PE and PP, improving surface adhesion. The hydrophobic polymer test is as follows:

Before plasma activation treatment, the water droplet angle is 68.5 degrees Before plasma activation treatment, the water droplet angle is 10.5 degrees

Conclusion: The surface of the same polymer is more hydrophilic after plasma cleaner activation treatment.

Note: After plasma cleaner activation, the result of activation is different according to the material and environment, subject to the actual product.

Scope of application of vacuum (low pressure) plasma cleaners: automotive manufacturing, automotive parts industry, medical technology, electronics industry, electrical engineering, chip industry, plastics processing and research and development.
