What is the reason why PET silicone-free release film loses silicone oil?

1. The product composition inspection is 100% free of silicone residues, the release effect is stable, and it is environmentally friendly.

2. PET release film is a high-end lamination isolation material with extremely high filling type, which can completely replace copper foil, PTX platen, and matte release film is the best choice for epoxy branch ester printed circuit board processing, isolation material , with high tensile strength and tear, small shrinkage, anti-sticking and high characteristics.

3. The surface is clean, no scratches, uniform coating, no transfer, small shrinkage.

Product use: Silicone-free release film, used in the manufacture of FPC/PCB/HDI/LCL/lamination and backlog circuit boards, the surface adopts a silicone-free coating process, which eliminates the problem of residual silicone oil pollution. Silicone-free release film is precisely for High-quality environmentally friendly products provided to customers to meet this demanding process.

What is the reason for the release of silicone oil from the release film?
The release film refers to a film that can be distinguished on the surface of the film. The release film does not have stickiness or slight stickiness after touching with a specific material under limited conditions. Usually, in order to increase the release force of the plastic film, the plastic film will be plasma treated, or coated with fluorine, or coated with a silicon release agent on the surface of the film raw material, such as PET, PE, PP, OPP, etc.

For a variety of different organic pressure-sensitive adhesives can show extremely light and stable release force. Depending on the release force of the release film required, the viscosity of the isolation product adhesive is different, and the release force is adjusted accordingly to achieve a very light and stable release force during peeling.

1. The temperature is too high during the use of the release film
2. Improper storage
3. Uneven coating

Release film is a material commonly used in thermal transfer printing. The substrate is PET, which is made by coating silicone oil, so it is also called silicone oil film. Conventional thickness from 25um to 150um. There are hot and cold tear and matte surface, through anti-static and anti-scratch treatment, the product has excellent adsorption and fit.
