Product characteristics analysis of PET silicon-free release film

Silicon-free release film is based on high flatness, high cleanliness polyester film as the substrate, thickness of 12μ-188μtransparent substrate and 12μ-100μmatte substrate. Combined with many years of practical experience, the use of imported silicon-free release agent has developed the top of the market silicon-free release film. The following is the product characteristics of PET silicon-free film.

First, product composition test 100% no silicone residue fruit stability, green environmental protection.

Second, the separation film is a high-end compression isolation material with a very high filling type, which can completely replace copper foil and PTX platener. Matte separation film is a good choice for epoxy branched ester printed circuit board processing. The isolating material has the characteristics of high tensile strength, high tearing, low shrinkage and high viscosity resistance.

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

Product Use: No silicon film, for the manufacture of FPC/PCB/HDI/LCL/ pressure layer and backlogged circuit board. The surface adopts non-silicon coating technology to eliminate the residual pollution of silicone oil. Silicon-free film is a quality and environmentally friendly product provided to customers to meet this demanding process.

What is the reason for desiliconizing the release film?

Release film refers to the film whose surface can vary. After touching the release film and specific data under limited conditions, it does not have viscosity or fine viscosity. Usually, in order to increase the release force of the plastic film, the plastic film will be treated by plasma, or coated with fluorine, or coated with silicon release agents on the surface of the film raw material, such as PET, PE, PP, OPP, etc.

For a variety of different organic pressure-sensitive adhesives, very light and stable release forces can be shown. According to different requirements, the release force of the release film is different, the viscosity of the isolation commodity glue is different, and the release force is adjusted accordingly, so that it can achieve a very light and stable release force when it is peeled.

About the silicone oil falling off

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

2. Improper storage;

3. Uneven coating.

Release film is a commonly used heat transfer material, its substrate is PET, also known as silicone oil film. The normal thickness is 25um to 150um. There are cold and hot tear and light matte surface. Through anti-static and anti-scratch treatment, the product has excellent adsorption and adhesion.
