Why is silicone rubber treated with plasma cleaning machine? The following are several common problems on the surface of silicone rubber that require plasma cleaning treatment to quickly improve surface adhesion.

1.During the production process, silicone rubber comes into contact with various organic impurities. For example, release agents are used during the molding process to facilitate the product's release from the mold, but residual release agents on the surface of silicone rubber can affect subsequent processing and use. In addition, during storage and transportation, the surface of silicone rubber is also prone to organic pollutants such as oil stains and fingerprints. These impurities will reduce the surface quality of silicone rubber, and with the help of popular plasma cleaning machines on the market, these organic impurities can be effectively decomposed and removed. After plasma cleaning, the organic pollutants on the surface of silicone rubber are thoroughly removed, providing a clean surface for subsequent processes.

2. Silicone rubber products may adsorb inorganic impurities such as dust and metal particles in the production environment. These particles can affect the appearance and performance of silicone rubber, such as in some electronic, medical, and other fields that require high cleanliness, even tiny particles may cause product quality issues. The plasma cleaning machine can remove these inorganic particles from the surface of silicone rubber through physical effects such as ion bombardment. Low temperature plasma can also form charges on the surface of silicone rubber, making it easier for dust and other particles to be attracted by static electricity and removed, reducing the chance of dust adhesion and improving the cleanliness of the silicone rubber surface.

3. Silicone rubber itself has relatively stable chemical properties, but its surface activity is low, which makes it difficult to combine with other materials or perform surface treatment. Plasma cleaning machine treatment can generate high-energy active groups such as hydroxyl and carboxyl groups on the surface of silicone rubber. These active groups can increase the chemical reactivity of the surface of silicone rubber, making it easier for it to react with other materials such as adhesives and coatings, thereby improving the performance of silicone rubber in bonding, coating, and other aspects. After plasma treatment on the surface of silicone rubber seals, the sealing effect between them and the mating components is significantly improved.

4. In many applications, silicone rubber needs to be bonded to other materials, such as sealing electronic devices and assembling automotive components. Untreated silicone rubber has a smooth surface and low chemical activity, with poor adhesion to adhesives. The plasma cleaning machine significantly improves the adhesion between silicone rubber and adhesive by cleaning the surface, increasing roughness and active groups, ensuring the firmness and durability of the bonding. In some situations where the surface of silicone rubber needs to have good contact with water or other liquids, plasma treatment can make it hydrophilic, which can improve its waterproof, anti fog, self-cleaning and other properties.

5. If paint, protective film or other coatings are to be applied on the surface of silicone rubber, the untreated surface may result in insufficient adhesion of the coating. The plasma cleaning machine can pre treat the surface of silicone rubber by removing surface pollutants and changing surface properties, so that the coating can better adhere to the surface of silicone rubber, prevent coating peeling, extend the service life of the coating, and improve the overall performance of silicone rubber products.

6. Plasma processing machines can form fine textures or patterns on the surface of silicone rubber for marking and printing. This has a wide range of applications in fields such as medical devices, electronic products, and automotive components.
