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

PTFE gasket is a product with excellent corrosion resistance, and its classification is also quite diverse. If the product we are using is pure tetrafluoroethylene gasket, then the materials used in its processing include polytetrafluoroethylene rod and tubular raw materials. After cutting, the product has anti-aging and non-conductive properties, and its corrosion resistance is relatively good. If we keep it between minus 100 degrees Celsius and 100 degrees Celsius, its mechanical strength is good and will not be affected in any way. If the temperature is below -185 degrees Celsius, its

The full name of PTFE gasket, also known as PTFE gasket or Teflon (Teflon, Teflon) gasket abroad, is a flat gasket, V-shaped gasket, piston ring, ball valve gasket, etc. made of PTFE rods, pipes, and plates by mechanical turning or cutting. It can also be pressed into a mold and high-temperature vulcanized into a molded PTFE gasket. Summarize the relevant advantages and introduction of PTFE gaskets by Ruichangxing. Tetrafluoride has excellent corrosion resistance, aging resistance, insulation, cleanliness and other good characteristics, so it is widely used in many fields such as chemical, petroleum, pharmaceutical, food and so on, known as the "King of Plastics". Polytetrafluoroethylene has polar properties

It is necessary to know how to choose a good PET silicone release film. Let's have a detailed explanation from Ruichangxing's editor below! In recent years, PET silicone release film has been widely favored by the market and consumers, and has been widely used for surface protection of various electrical and electronic products, such as notebook Computer keyboard keyboard release film, liquid crystal release film, LED release film, mobile phone release film, clothing processing, industrial packaging, etc. Now let's get to know the advantages and relevant knowledge of PET silicone release film together with fluoride release film manufacturers of Ruichangxing Technology Co., Ltd. What are the advantages of PET silicone release film? Because PET

Release film is a type of release film that applies silicone release agent to the surface of environmentally friendly PET/PE/OPP release film, allowing it to exhibit extremely light and stable release force against various organic pressure sensitive adhesives. Different organic pressure sensitive adhesives, such as hot melt adhesives, acrylic adhesives, and pressure sensitive adhesives for rubber systems, require different release film release forces, also known as release film, isolation film, separation film, release film, silicone oil film, and anti mucosal film. PET release film plays an important role and effect in the daily production of Double-sided tape. Today I would like to share with you the role of PET release film in production. If die-cutting double

The selection principle of PET release film: Different surfaces require different stickiness. Similarly similar protective film surfaces may require different materials to have different stickiness. The subsequent processing steps are the key to determining viscosity. The subsequent processing of protective film generally includes bending, stamping, cutting, drilling, Thermoforming, etc. Reasonable combination of PET release film thickness and viscosity; The tensile strength and elongation of the protective film are to ensure that the flexibility and strength of the protective film meet the requirements. In addition, it is necessary to conduct sufficient testing on the quality and performance of PET release film to ensure that it can meet the usage requirements. PET release film is as easy to use as a tape. however
