Silicon free release film is made of high flatness and high cleanliness polyester film as the substrate, with a thickness of 80~120μm. Based on years of practical experience and the use of imported silicon-free release agents, we have developed a top market non-free release film. 

The following is the characteristics of PET silicon-free film.

1. Product composition inspection100% silicone free and stable fruit, green and environmentally friendly.

2. Separation film is a high-end compression isolation material with extremely high filling capacity, which can completely replace copper foil and PTX pressure plate. Matte separation film is the best choice for processing epoxy branched ester printed circuit boards. Isolation materials have the characteristics of high tensile strength, high tearing strength, low shrinkage rate, and high resistance to adhesion.

3. The surface is clean, without scratches, evenly coated, without transfer, and has a low shrinkage rate.

Silicon free film used for manufacturing FPC/PCB/HDI/LCL/pressure layers and backlog circuit boards. The surface adopts a silicon free coating process to eliminate residual contamination of silicone oil. Silicon free film is a high-quality and environmentally friendly product provided to customers to meet this demanding process.

What is the reason for the silicone oil removal from the release film?

After comparing with specific data, it does not have viscosity or fine viscosity. Usually, in order to increase the release force of plastic films, they are treated with plasma, coated with fluorine, or coated with silicon release agent on the surface of the film material, such asPETPE, PP, OPP, etc.

Regarding various types of organic pressure sensitive adhesives, they can exhibit a very lightweight and stable release force. According to different requirements, the release force of the release film varies, and the viscosity of the isolation product adhesive also varies. The release force is adjusted accordingly to achieve a very light and stable release force during peeling.

The claim about silicone oil detachment

1. The temperature is too high when using the release film;

2. Improper storage;

3. Uneven coating.
