Many users do not have much understanding of PET release films, and they often encounter various problems when purchasing release films. Are release films and film products the same? Today, as a professional manufacturer of PET release film, I will talk to you. When purchasing release films, users should note that there is a certain difference between this type of film and ordinary film products. Film products do not have any adhesive coating on them, so when touching the surface of the film with their hands, there will be no viscosity. Release films and film products have differences in production technology and feel. When making PET release films, PET will be used as the original

PE protective film for automobiles plays a great role in our daily life and industrial production. Our phones, computers, and monitors all rely on protective film protection. So what is the lifespan of the PE protective film applied to the car? As is well known, a good car protective film is usually used normally for 5 to 6 years, but the premise is to maintain it well. If the precautions for car protective film are not clear, the service life of the car protective film will be greatly reduced, which is inevitable. 1. Do not lift the glass within a week. Generally speaking, it takes 5-7 days for the car protective film to firmly adhere to the window. During this period,

For silicone gaskets, they can be used in different scenarios, and different scenarios require silicone gaskets to play different roles. At this point, we need to choose the appropriate silicone gasket according to the requirements of different scenarios. Let's learn about the classification of silicone gaskets and the applicable scenarios together. 1. Thermal conductive silica gel pad Thermal conductive silica gel sheet is a kind of thermal conductive medium material synthesized by a special process with silica gel as the base material and various auxiliary materials such as metal oxides. In the industry, it is also called thermal conductive silica gel pad, thermal conductive silicone film, soft Thermally conductive pad, thermal conductive silica gel pad, etc. Control motherboard for electronic and electrical products, as well as internal and external pads for motors

Silicone gaskets are widely used in electronic products. The main function of silicone gaskets is to use gaps for heat transfer, playing a role in insulation, shock absorption, and sealing. However, due to improper usage, some customers did not achieve the desired results and instead damaged the silicone pad. What should be noted when using silicone pads? Firstly, the silicone pad surface should be kept clean to avoid sticking to dirt, resulting in poor self-adhesion and sealing thermal conductivity. Secondly, when taking a large area of thermal conductive silicone gasket, it should be taken from the center, as the uneven force on the large silicone gasket can cause deformation and affect subsequent operations. Thirdly, when using, take the tablet with the left hand and tear off a protective film with the right hand. Don't be the same

PET release film plays an important role in the production of double-sided tape. If die cutting double-sided tape requires release film, the key characteristics of release film are coating uniformity, high residual adhesion, flatness and high cleanliness. What should be paid attention to when using transparent pet release film? 1. High residual adhesion: the residual adhesion should be affected by silicone oil formula, coating conditions and substrate treatment, The technical services of silicone oil factories also need to be strengthened. 2. Coating uniformity: The release film should be evenly coated. In addition to selecting appropriate solvents, controlling the concentration, viscosity, and solvent evaporation time of the coating agent, the coating equipment is crucial

The material of the hot press release film is PET compound. Although the product contains silicon, the content is extremely low, and a special surface treatment method is used to make the product pollution-free (silicon removal, silicon transfer) to the circuit board, so it can be comparable to the silicon free release film. Hot press release film products have high tensile strength and tear resistance, chemical inertness, thermal stability, and non stick properties. The surface of the film is flat and smooth, without wrinkles, tears, particles, bubbles, and foreign impurities. It has excellent physical and mechanical properties, small thickness tolerance, high temperature resistance, stable size during pressing, and moderate price, as well as the safety feature of not supporting combustion. As a result, it becomes a multi-layer board generator

The selection method for release film is actually very simple, similar to choosing clothes. So how can you quickly distinguish between genuine and fake release films? In fact, choosing a release film is a very simple matter. Now, when it comes to choosing a release film, you can verify it through the following methods: Firstly, if the smell is strong and there is a sour odor, the retention of this protective film is very poor, especially in low temperature environments. Basically, the sealing adhesive that sticks to the cardboard box will crack, and the initial adhesion is still very sticky when the smell is stronger, but the adhesive surface will soon become dry, If the adhesive is lost, there will be cracks on the surface of the protective film, which is because

With the popularity of smartphones, curved screen smartphones have caused waves in this industry. Major well-known phone manufacturers have invested in this research and frequently launched new products, making curved screens a new milestone in the history of smartphone screen innovation from last year to this year. With the popularity of curved screen smartphones, the reality behind it represents the gradual maturity of flexible screens. Curved screens, as the name suggests, have a certain degree of curvature. Later, with the development of technology, the screen itself can also be bent, which requires that the functions and characteristics of the phone protective film must comply with the characteristics of curved screen phones, which is the curved surface we will talk about

Below, the editor of Ruichangxing will talk about the six major functions of anti-static ionization type films: release films are increasingly used in electronic products, especially with the rapid development of FPC soft boards. Previously, non anti-static release films were used, and the process did not meet the requirements. However, for electronic products, anti-static protection is very important, so ordinary release films can no longer meet the production and use of electronic products, Perhaps this is the survival of the fittest in technological development. If we cannot meet customer demand, there will gradually be no market. As long as there is customer demand, there will be a market. Ruichangxing anti static ionization film will develop into a trend in the future. 1. Adhesive separation

In the selection of release film, the main considerations include cost, product quality, production process, characteristics of the prepared product, and usage situation! Product features: 3M imported tape, such as Nippon, Sony, Desa, and some domestic tapes, are commonly used in China. Because different tapes have different adhesive properties. This determines that we need to consider this aspect when selecting release membranes. Cost: There is a significant difference between domestic and imported release films, and generally speaking, the taste of domestic release films is not very good. For example, sometimes there may be surface release defects during adhesive preparation, and the release film and product cannot be easily torn apart. Of course, the current domestic technology is

A good polarizer release film often achieves good results through the selection techniques of polarizer release film. Therefore, the editor of the release film manufacturer will explain in detail the precautions for selecting polarizer release film! 1. Looking at the manufacturer: Generally speaking, formal polarizer release film manufacturers with large brands and high evaluations are relatively mature in technology and services, have strict requirements, and have a relatively large production scale, thus having a certain foundation, technical and scale. So, try to choose this type of release film manufacturer as much as possible. 2. Depending on usage: purchasing polarizer release film

1： After the adhesive tape and release film bonding machine are released, some of the adhesive tape will be released and there will be a "pa" or "pa" sound. Reason: When getting rid of it, there is a sound, which is initially caused by the excessive release force of the release film, followed by uneven glue adjustment. 2： Causing anti escape, the raw materials that should be removed have not been removed. Reason: The direct cause of the reverse detachment is the irrational combination of the release force of PET release film. Due to the unqualified original inspection of the release film, incomplete inspection machinery and equipment, and unstable production process, the release force of this specification and model of release film will be uneven and the voltage will be quite high. 3： After punching and placing for a period of time, release film and adhesive
