Many people are not aware of the advantages of PET release membranes. Today, let me introduce it to you. PET release film has good function in protecting golden fingers, as its own function has already met the requirements in this regard. What requirements can it meet? Firstly, its high-temperature resistance function, it can reach a high temperature of 300 degrees Celsius, and can continue to deform in an environment of 300 degrees Celsius for ten minutes. If the environment is 180 degrees Celsius in the morning, it can continue for a longer time. This is also what alloy fingers need, and then there is its insulation. The golden finger is an electronic product, so as an important information to protect it,

The release film is coated with silica gel release agent on the surface of environmental protection material PE/OPP/PET film to enable it to show a very light and stable release force. It is used for various organic pressure sensing adhesives, different organic pressure sensing adhesives, such as Hot-melt adhesive, pressure adhesive, rubber system pressure sensing adhesive, etc The required release force of the release film varies, and the release film is also known as peel off film, isolation film, separation film, release film, silicone oil film, and anti mucosal film. PET release film plays an important role in the daily production of Double-sided tape. Today I would like to share with you the role of PET release film in production. Like die-cutting on both sides

Introduction to the functions, characteristics, and uses of release film. The Z standard of the finished product is 5mm, with a ± tolerance of only 0.1 mm. PET release film is generally used to isolate adhesive materials, and is widely used in professions such as electronics, mobile phones, adhesives, printed circuit boards, packaging, printing, silk screen, pad printing, nameplate, thin film switch, flexible circuit, insulation products, circuit boards, laser anti-counterfeiting, bonding, electronics, sealing materials, reflective materials, waterproof materials Professional fields such as medicine (plaster paper), sanitary paper, adhesive products, die-cutting and punching processing, suitable for heat transfer printing, and more suitable for die-cutting gaskets and adhesive products

In FPC production, release film/release paper is generally required, and the main functions of release film are isolation, filling, protection, and easy peeling. With the development of the electronics industry, the demand for release film/release paper is increasing. However, in order to control production costs, domestic release film/release paper has to be used. Below is a summary of the reasons for the rapid development of release films/release papers in China: 1. Product characteristics: Currently, the commonly used release films/release papers in China are Sanzhi from South Korea, Sumitomo/Mitsui TPX/Shuishui/Nippon release films from Japan, and 3M from the United States. Because different tapes have different adhesive properties. this

Let's first understand that the items to be tested for release film include: color, appearance, curl, thickness, dry solids, surface resistance, peeling force, residual adhesion, and aging test, totaling 9 items. Color, appearance, curliness, and thickness can be easily measured with a simple naked eye and caliper, while dry solid content, surface resistance, and aging test are mainly electrical characteristics that are not required for general industrial applications, so they can be neglected. So, for the testing of release membranes, Z will mainly focus on measuring the release force! So how should the release force of the release membrane be tested? There is a lot of information about this online

What are the issues and effects of using some defective adhesive on PET release film? Some people feel sticky with the adhesive tape, but the sealing effect is not good enough. They always think they just opened it, and any chosen golden finger adhesive tape has the same quality of life? This is the problem with the glue. It feels very sticky to the touch, and the initial adhesion is good. After the glue jumps away, the adhesion is not good enough to grip. Double-sided tape die cutting professional Double-sided tape adhesive technology can not only solve all bonding problems, but also has a wide range of applications: whether in metal bonding, powder spraying surface, glass, plastic or fiber and other materials, Double-sided tape can

PET release film is made by coating a thin and uniform release agent on the surface of the PET substrate. PET release film has excellent high-temperature resistance function. Its physical characteristics are: smooth appearance, no particles, no bubbles, no wrinkles, etc. It is very suitable for processing various materials. Next, some of the main uses of PET release film materials were introduced. 1. Many links in the professional mobile phone production industry chain cannot be separated from PET release film materials, such as OCA optical adhesives used for screen structures. 2. Die-cutting profession 3, adhesive product profession 4, printed circuit board profession 5, packaging profession 6, silk screen profession 7, film switch production 8

For a product, we not only need to know its usage method, but also the storage method, so that it can be directly stored when not in use. If the incorrect method is used, it will affect the quality of the product, and the release film is the same. So what are the usage and storage methods of the release film? 1、 Storage 1. Store in a ventilated space or a cool place, and the temperature range should be kept between 5 ℃ and 32.5 ℃ 2. Keep away from ignition sources and compatible materials: strong alkali, Mineral acid, ammonia, chloride, strong oxidant. 3. Keep the container tightly closed when not in use. four

There is a word difference between release film and release paper, but there are significant differences. Release film is used to coat organic silicon release agents on the surface of environmentally friendly PET, PE, and OPP films, thereby exhibiting extremely light and stable release force on various organic pressure sensitive adhesives. Different organic pressure-sensitive adhesives, such as Hot-melt adhesive, acrylic adhesive and rubber system pressure-sensitive adhesive, require different release force of release film. Products with different viscosities need to be isolated. Adjust the force accordingly to obtain a very light and stable release force during stripping. The classification of release films can be divided into different substrates: PE release film, PET release film, OPP release film, and composite release film（

The function of release film is achieved by using different coating liquids, such as polyester type, polyurethane type, acrylic acid, silicon solution, etc. The purpose of coating the release film is to enhance its specific appearance function, such as enhancing film printing function, enhancing the aluminum layer peeling force after aluminum plating, and improving the smoothness of the film surface. When using different coating fluids for coating, it is necessary to adjust the corresponding production process accordingly to meet the technical requirements such as the curing time and temperature of the coating fluid, in order to ensure the stability of the coating production. Regarding equipment coating fluid: The coating fluid produced is generally water-based
