High temperature resistant release film: it is made of polyimide film as the base material, coated with imported high temperature resistant silicone pressure sensitive adhesive, and then coated with polyester release film. Tape has excellent high temperature resistance, electrical insulation, and chemical resistance; And it is non-toxic, odorless, and harmless to the human body and environment, due to its extremely low release force.

The circuit board pressure transmission and pressing cushion pad is developed and produced for the ultra-high temperature press currently used in the PCB industry. When the circuit board pressing temperature exceeds 260 ℃, the general Kraft paper, cushion pad and other auxiliary materials can no longer meet the pressing demand of high temperature, and fiber materials with higher temperature resistance must be used. At present, this RCX-K25 cushion has excellent temperature resistance and can meet the requirements of ultra-high temperature pressing.

ETFE release membrane is academically known as Teflon release membrane, Teflon release membrane, Teflon release membrane, Teflon release membrane, Teflon release membrane, Teflon release membrane, etc. It is a polymer compound formed by polymerization of tetrafluoroethylene, with excellent chemical stability and corrosion resistance. It is one of the best corrosion resistant materials in the world today. Ruichangxing produces and acts as an agent for various types of Teflon films, such as PTFE, FEP, ETFE, PFA, ECTFE, PVDF, PMP, etc., as well as products such as fluoropolymer casting films MR, VB, DF100, etc.

The key points for controlling the quality of release film include coating uniformity, high residual adhesion, flatness, and high cleanliness. Manufacturers generally control the quality of release film from the following four points.

1： Basic information

Release film refers to a thin film that, under limited conditions, does not produce stickiness or slight stickiness when in contact with a specific material, and can distinguish the surface of the film. 1、 The use and characteristics of silicone oil release film are selected with good PET substrate, which has uniform and stable release force, non static/single (double) anti static, and diverse thickness and color. It is mainly used for non drying adhesive tape, double-sided adhesive tape, precision material die-cutting, etc. The silicone oil release film used in the graphite industry has uniform and stable release force, ultra-light/overweight release force, thickness, and multiple colors. According to customer requirements, the release force is 300-400g, which can also be used as an anti-static layer,

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
