Why Silicone Oil is Applied to PET Plastic Sheets

The main purpose of applying silicone oil to PET plastic sheets is to improve the surface properties of the material, making it more efficient and practical during processing and application. Specifically, applying silicone oil to PET sheets has the following major effects:

Enhance anti-sticking properties:

PET sheets have a certain surface tension. When stacked or wound, the sheets may stick together, making separation difficult. After applying silicone oil, an extremely smooth coating will form on the surface of the sheet, significantly reducing friction, thereby effectively preventing the problem of adhesion between sheets and facilitating subsequent processing and use.

Improve thermoforming performance:

During the thermoforming process of PET sheets, applying silicone oil helps reduce the adhesion between the sheet and the mold, facilitates mold demolding, and improves the efficiency and quality of molding. The lubricating properties of silicone oil can ensure that the surface of the thermoformed product is smoother and reduce defects caused by adhesion.

Reduce static electricity accumulation:

PET sheets are prone to accumulate static electricity during processing and use, especially in high-speed production lines or when there is more friction. Static electricity can cause the sheet to absorb dust or other tiny particles, affecting the appearance and cleanliness of the product. After applying silicone oil, the static electricity on the surface of PET sheets will be significantly reduced, thereby reducing the pollution problems caused by static electricity.

Improve processing efficiency:

PET sheets coated with silicone oil are easier to cut, press, print and other processing operations, avoiding stagnation or jamming on the surface of the sheet due to friction or adhesion. This can improve the operating efficiency of the production line, reduce equipment loss and processing problems.

Improve surface smoothness and touch:

PET sheets coated with silicone oil have a smoother surface and a smoother feel, which helps to improve the appearance and quality of the product. In some applications that require better texture, silicone oil coating can provide sheets with better surface effects.

Application field requirements:

In some specific application fields, such as food packaging, medical device packaging, etc., PET sheets are required to have better surface properties and processing convenience. Silicone oil coating can meet these special needs and improve the use effect of PET sheets in these fields.

Applying silicone oil to PET plastic sheets can improve surface smoothness, anti-adhesion, reduce static electricity, improve processing efficiency and other aspects of performance. This treatment method brings many advantages in the production and subsequent applications of PET sheets, especially in thermoforming, packaging and efficient processing.
