Silicon free release film use high flatness and high cleanliness polyester film as the substrate, with a thickness of 12 μ- one hundred and eighty-eight μ Transparent substrate and 12 μ- one hundred μ Combining years of practical experience with imported silicone free release agents for matte substrates and coatings, we have developed silicone free release films at the top of the market. The following explanation will be explained below.

Product Features

1、 The product ingredient test shows 100% absence of organic silicon residue, stable release effect, and is green and environmentally friendly.

2、 Release film is a high-end pressed isolation material with extremely high filling capacity, which can completely replace copper foil. PTX pressure plate and matte release film are the preferred choices for processing epoxy resin printed circuit boards. Isolation materials have high tensile strength, high tearing strength, low shrinkage rate, and high adhesive resistance.

3、 The surface is clean, without scratches, the coating is uniform, without transfer, and the shrinkage rate is small.

Product Usage: Silicon free release film, used for FPC/PCB/HDI/LCL/made of laminated and stacked circuit boards. The surface adopts a silicon free coating process to eliminate residual silicone oil pollution. Silicon free release film is a high-quality and environmentally friendly product provided to customers to meet this demanding process.

What is the reason for removing silicone oil from release film

Release film refers to a thin film that has no viscosity or slight viscosity after contact with specific data under limited conditions. Usually, in order to increase the release force of plastic films, plasma treatment, fluorine treatment, or silicon release agents such as PET.PE.PP.OPP are used.

Various types of organic compression adhesives can exhibit very light and stable release forces. Depending on the required release force of the release film and the viscosity of the isolation product adhesive, the release force is adjusted accordingly to achieve a very light and stable release force during peeling.

The theory of silicone oil loss

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

2. Improper storage

3. Uneven coating

Release film is a commonly used data in heat transfer printing, and substrate is a commonly used data in heat transfer printing. PET, also known as silicone oil film. The customary thickness starts at 255. Um to 150um. Cold and hot tearing and matte surface, with anti-static and scratch resistant treatment, the product has excellent adsorption and adhesion.
