Recently, I have received many inquiries from friends to understand the quality issues with release membranes. We know that as a manufacturing industry, encountering quality problems is inevitable, and the most crucial thing is to understand the problem and solve it. We can better control the quality of the release film only after we know what quality issues may arise. What quality issues typically occur with release films? Below, Ruichangxing will share it with everyone. 1、 The scratch on the surface of the release film is a quality issue characterized by scratches on the flat surface of the film material, forming fine groove lines that can be observed through reflection. Scratches on the film surface can be divided into large-scale scratches and intermittent scratches

Fluorine release films require the selection of high-tech materials for product development, and low coating release films should be used for adhesive. The medium coating release film is more suitable for using oil glue and protective film, while the high coating release film is not suitable for using protective film. In terms of material performance, industrial materials must be adhered to so that they can be easily separated; Fluoride release membranes usually do not undergo chemical reactions with the resin system or contaminate the resin system; The elongation of the stretched release film is necessary. It can be consistent with the fibers to prevent deformation and distortion of the prepreg during the preparation process due to asynchronous stretching. Production Procedure: The key is whether to press or cut. During stamping and cutting, fluorine

We have previously mentioned that PET protective film is generally used for the protection of transportation products, lens and screen protection, material transfer, and waste disposal. What is the use of pet release film? In fact, people in the industry are well aware that it is generally used as a backing paper for adhesive products, automotive parts, electronic components, and die-cutting. Today, we will classify release membranes and explain their uses. 1、 What is the silicone oil release film used for? The release film commonly referred to in the industry is also known as silicone oil film. Silicon oil film applications can be divided into two categories: applications in the die-cutting industry and applications in the graphite industry. Silicon oil film applied in the graphite industry has uniform release force

PET release film is a common material in the heat transfer printing process, with a normal thickness of 25um to 150um. It has a cold, hot, and smooth matte surface, and has undergone anti-static and scratch resistant treatment. The product has good adsorption and adhesion performance. PET release film plays an indispensable role in daily life and work, and is a kind of Household goods. In various fields such as packaging printing, insulation products, reflective waterproofing, etc., release films can be seen, and due to their excellent high-temperature resistance characteristics, they play an important role in die-cutting and adhesive products. This type of material with single or double sided coating treatment has a smooth and clean surface, a flat and even surface without wrinkles and air

Release film is a silicone release agent applied to the surface of environmentally friendly materials such as PET, PE, and OPP films, 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 forces for the release film. Depending on the viscosity of the adhesive that needs to be isolated, the release force should be adjusted accordingly to achieve an extremely light and stable release force during peeling. A brief explanation of the differences between peel off film and release film. Release film refers to a thin film that can be distinguished on the surface. Release film and specific materials under limited conditions

Let's take a look at the difference between ordinary plastic film and release film. Cut a piece of tape, stick it to these films separately, and then peel it off. It feels easy to peel off, and during the peeling process, there is no sound, which is the release film coated with silicon, but it is difficult to peel off. During the peeling process, there is a chirping sound, which is the ordinary plastic film not coated with silicon. This method can also distinguish whether it is a single silicon release film coated on one side or a double silicon release film coated on both sides, and even compare which side is coated with silicon, the amount of silicon, and the size of the stripping rate. Using a water pen to detect, once you scratch the surface of the release film, no ink can be drawn on the surface, while ordinary

PET matte blue release film, also known as matte blue release film. It is based on the original PET transparent film. After adjusting the raw material formula and adding silica, apply silicon or fluorine to the surface of the film to make the blue release film non stick or slightly stick when in contact with specific materials under limited conditions. TPX matte blue release film is mainly used for FPC flexible printed circuit boards, die-cutting industry, outer packaging, and automotive insulation. Production of blue release film: PET blue release film, also called heat transfer film, heat insulation film, synovial film, Tiannan paper, silicone oil film, anti mucous membrane, silicone oil release paper, silicone oil paper, hole facial mask, PET blue release film is also called PET release film

Release film refers to a thin film that can be distinguished on the surface, and it does not have viscosity or slight viscosity when in contact with a specific material under limited conditions. 1、 The use and characteristics of silicone oil release film: the application of silicone oil release film in die-cutting and graphite industries. The selected PET base material, with uniform and stable release force, non antistatic/single (double) antistatic, and various thickness and color, is mainly used in dry tape, double-sided tape profession, precision material die-cutting and other professions. Silicone oil release film used for graphite profession has uniform and stable release force, ultra-light/overweight release force, thickness, diverse colors, and release force of 3-4 00

Today, the editor of Ruichangxing will share with you about how to choose a fluorine release film manufacturer. Firstly, we need to know its functions. In fact, there are two main points. The first function is to prevent the prepreg from being contaminated, and it can also draw lines on its surface, providing convenience. The second function is to prevent lateral cracking of unidirectional prepreg. So, what conditions should high-quality fluoride release membranes meet? Let's explore together. Condition 1: It can adhere to the prepreg, but at the same time, it can easily separate the two. Condition 2: No chemical reaction or contamination with the resin system. Changes in ambient temperature or humidity

Fluorine release films require the selection of high-tech materials for product development, and low coating release films should be used for adhesive. The medium coating release film is more suitable for using oil glue and protective film, while the high coating release film is not suitable for using protective film. In terms of material performance, industrial materials must be adhered to so that they can be easily separated; Fluoride release membranes usually do not undergo chemical reactions with the resin system or contaminate the resin system; The elongation of the stretched release film is necessary. It can be consistent with the fibers to prevent deformation and distortion of the prepreg during the preparation process due to asynchronous stretching. Production Procedure: The key is whether to press or cut. During stamping and cutting, fluorine

Next, Ruichangxing will introduce two different types of membranes, release membranes and protective membranes. Industry newcomers may easily confuse these two types of protective membranes. What are their differences and what are their respective uses? Let's take a look at the release film manufacturer Ruichangxing. From the perspective of material differentiation, PET protective film is coated with adhesive of different viscosities on PET material. It is divided into three types: high viscosity, medium viscosity, and low viscosity, which have adhesive protection effects. Its scope of use is to fit with release film or release paper, cut into different product shapes, tear off auxiliary materials, and transfer them to other products, such as mobile phones, computers, etc., to play a screen saver role. PET release film

Currently, we still use a variety of products in our daily lives, especially PET release film which is widely used in daily life, such as in the automotive industry, as well as in high-temperature spray painting of plastic and furniture surfaces, which can be used well. However, in addition to using the product in the correct way, it is also necessary to preserve the product. What is the current method of product preservation. 1. Pay attention to the specific environment during storage. If the PET release film needs to be stored, it is still necessary to pay attention to the storage environment, especially when placing it in the warehouse to prevent exposure to sunlight or rain
