1. After being attached to the tape, it cannot be peeled off, which is usually caused by uneven application. Some release films that are severely missed can cause a certain part to have no release effect, resulting in the tape being unable to be peeled off. This problem should be avoided in circular knife die-cutting. 2. The oily release surface is mainly caused by the isolation agent system, and it is not necessarily bad for oily things. In fact, some oily release films are evenly coated on the surface and have better residual adhesion. But some are purely poor in sealing, and silicone oil is prone to detachment. These can also be determined through detection. 3. Electrostatic problems, in addition to physical treatment methods, generally involve chemical aspects

PET release film is the most basic auxiliary material commonly used in the production process of die cutting factories. Therefore, the release film manufacturer has summarized several common problems and solutions in the application of PET release film in the die cutting process. In the process of die-cutting, the release film usually encounters the following problems: 1. After the Double-sided tape is bonded with the PET release film, some double-sided tape will peel back and make abnormal sound when peeling. 2. Anti stripping refers to the material that has not been stripped. 3. After punching and placing for a period of time, the tape and PET release film cannot be peeled off. 4. The release force of PET release film is very low, and it feels like the release layer is very strong

Release film is a commonly used material for heat transfer printing. PET, also known as silicone oil film, is coated with silicone oil. Cold and hot tearing and matte surface, after anti-static and scratch resistant treatment, the product has good adsorption and adhesion. A good release film requires high-quality pet substrate with moderate softness and hardness, uniform and stable release force, high cleanliness, no appearance bubbles, and no setbacks and noise during peeling. What is the purpose of the release film? What types of release membranes are classified? Which industry is it mainly used in? At present, release films have been widely used in packaging, printing, screen printing, pad printing, engraved plates, thin film switches, flexible circuits, insulation products, circuit boards, lasers

PET release film is a material commonly used in heat transfer printing. Its substrate is PET, which is coated with silicone oil, so it is generally also called silicone oil film. The conventional thickness ranges from 25um to 150um. There are two types of products: cold and hot tearing, as well as smooth and matte surface. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion. This is also one of the differences between PET protective film and PET release film. The characteristics of PET release film: PET release film has high transparency, non-toxic and odorless, high tensile strength, good stiffness, anti cracking, not easily damaged, excellent electrical and optical properties, good oxygen and moisture resistance, cold resistance, and resistance

Fluorine release film, also known as fluoroplastic release film, is mainly used for isolating adhesive materials, such as silicone tape, PI tape, etc. During production, storage, or transportation, the fluorine release film protects the adhesive from contamination and deterioration. At present, tape or tape products are widely used as carriers. Fluoride release membrane properties: 1. The color generally includes transparent and milky white. 2. There is no migration phenomenon, eliminating the danger of silicone release film transferring to nearby materials. 3. Controllable release force, high glossiness, high cleanliness, residual adhesion of 94%, and good surface performance of fluorine release film. 4. Has good UV aging resistance, chemical corrosion resistance, and solvent resistance

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, the testing of release membranes will mainly focus on the detection of release force. So how should the release force of the release membrane be tested? There are many materials in this field online, here is a brief list

The editor of Ruichangxing summarized the following six tips for purchasing PET release films to help you make the purchase. 1、 Pay attention to the scope of use of the release film. The main purpose of purchasing PET release film for enterprises is to meet the production needs of the product. Therefore, it is necessary to choose according to the scope of use of the release film to ensure that it meets the production requirements of the enterprise's products. For example, PET release films used for sealing tapes, waterproof rolls, etc. are suitable for selecting single-sided release films; For the protection of reflective materials with adhesive backing, it is suitable to choose a double-sided release film. 2、 Pay attention to the characteristics of the release film, although the same type is used in the production of PET release film

Many people may wonder what the charm of release membranes is, and why do so many people choose professional release membranes? Below, let's let Ruichangxing's editor uncover your doubts. 1. The versatile release film can be well applied in the decoration of houses, can be used as a good building material, and can help people build a warm home, so it is a very worthwhile material for people to use. In addition, it can also be used as an adhesive for various professional molds, and in short, it has many uses. 2. The strong tension release film has good tension, which can not only improve the adaptability of printing, but also enhance the adhesion of the vacuum aluminum coating. these

Next, Ruichangxing Xiaobian will analyze the following factors that affect the appearance quality of PET release film: 1. Coating head At present, the coating head widely used by silicon coating enterprises in China is mainly scrapers/Anilox/roller coating/multi roller roller coating. It's just a slight improvement in appearance and performance. Essentially, the improvement should not exceed 20%. However, in foreign countries, micro engraving rollers with a certain angle are used for coating, which has improved transparency from an optical perspective. At the same time, it completely eliminates the possibility of rainbow patterns appearing. 2. Composition of coating agent formula Currently, the widely used coating agent in China's silicon coating enterprises is commonly known as 120#

There are many types of silicone products that have been applied in many industries, and silicone products are often seen in daily life. Silicone gasket is a type of silicone product that is required in many scenarios. Today, the editor of Ruichangxing will take you to understand the classification of silicone gaskets. Let's take a look together. Thermal conductive silica gel gasket 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, adding 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 gasket, etc. Control motherboard for electronic and electrical products, electrical

Silicone gaskets are widely used in electronic products, mainly for insulation and shock absorption. However, many consumers, after purchasing, not only fail to use silicone gaskets or operate them improperly, but also damage them. So, how to use silicone gaskets? Next, let's learn about it with the editor of Ruichangxing. Firstly, the silicone pad surface should be kept clean to avoid sticking dirt, which can lead to poor self-adhesion and sealing thermal conductivity. Secondly, when taking a large area of thermal conductive silicone pad, it should be taken from the center, as the uneven force on the large silicone pad can cause deformation and affect subsequent operations. third
