Firstly, substrate: PET release films are coated with release agents on the surface of PET films, and the quality of the substrate directly affects its performance. Domestic PET film substrates lag behind foreign countries in terms of thickness control and thermal shrinkage. 2、 Residual adhesion rate: refers to the residual adhesion rate of release paper after being opened

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 decision

With the development of technology, there are many materials in the market today, such as PET release film. We often see it on the market. The most common one is a three-layer transparent PET release film, which is mainly used for surface protection of mobile phone screens, tablet screens, and other products. So what are the specifications of PET silicone protective film? Below, the release film manufacturer Ruichangxing will introduce it to you. According to different substrates, it can be divided into PE release film, PET release film, OPP release film, and composite release film. According to the release force, it can be divided into light release membrane, medium release membrane, and heavy release membrane. By color

Nowadays, many products closely related to our daily lives are equipped with a protective layer as their purpose. However, the release film may seem simple, but if not selected professionally, it may lead to a decrease in product quality and prevent it from being put into the market. However, choosing the right release film can better protect your product and improve market competitiveness. So how do we choose PET release film? 1、 Pay attention to the characteristics of the release film. Although the same substrate is used in the production of PET release film, using different release agents will result in different release film characteristics, and the fields and scope of use also have different focuses. So, companies are

Non silicon release film has excellent corrosion resistance, electrical insulation (especially high-frequency insulation), can be chlorinated, modified by irradiation, and can be reinforced with glass fiber. The melting point, rigidity, hardness, and strength of low-pressure polyethylene are high, and the water absorption is small. It has good electrical performance and radiation resistance; High pressure polyethylene has good softness, elongation, impact strength, and permeability; Ultra high molecular weight polyethylene has high impact strength, fatigue resistance, and wear resistance. Low pressure polyethylene is suitable for making corrosion-resistant and insulating parts; High pressure polyethylene is suitable for making films, etc; Ultra high molecular weight polyethylene is suitable for making shock absorption, wear resistance, and transmission parts. Non silicon release film, produced by the release film manufacturer

Matte release film, also known as matte release film, matte film, PET matte film, TPX matte release film, fluoroplastic release film, and fluoroplastic release film. PET matte film is based on the original PET transparent film, with appropriate adjustments to the raw material formula. After the addition of silica, the peel film is not sticky or slightly sticky after contact with a specific material under limited conditions. TPX matte release film is mainly used for FPC flexible circuit boards, die-cutting industry, food packaging, automotive insulation and insulation. The advantages of matte release film include easy peeling of the board surface, support for PIN hole service, smooth film surface, film cleaning, film toughness/operator

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 and printing, insulation products, reflective waterproofing, etc., release films can be seen. Moreover, due to their excellent high-temperature resistance, 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, with a flat and uniform surface without wrinkles or wrinkles

Generally speaking, a good release membrane should be able to adhere to the prepreg, but it should be easy to separate the two and not react chemically with the resin system; When the environmental humidity changes, the length and width of the release film should remain unchanged. How can we choose a high-quality release film? Below, we will explain how to select release membranes from the following four aspects. 1. Selection based on the characteristics of the prepared products: Currently, most of the commonly used adhesive tapes in China are imported, and different adhesive tapes have different characteristics, which determines that we need to consider this aspect when selecting release films. After the release membrane is pulled, its elongation and fiber should be maintained

A material used in the pressing of electronic industry circuit boards is a matte release film. It is a type of release film, not a protective film, but a process used in the production of flexible circuit boards. It places a matte release film above and below the soft board. After the high-temperature grinding tool is pressed, remove the release film and throw it away. So, does the matte release film seem to have little effect? Since it has no effect, why have circuit boards been pressed with matte release film? Why protect our phone screens? Why do we need to apply tempered film? In fact, the facts are the same. It can prevent scratches and damage. The same applies to release membranes. Its functions are as follows: 1

High temperature resistant release membrane structure: The release membrane has a three-layer structure, which is the base paper, the coating, and the silicone oil. Release film, also known as isolation paper. Double silicon release film is a release film made by applying release agent to the original paper after overpressure. The weight is about 60g to 200g. Its range of use is mostly adhesive, which is a common industrial paper with anti stick function to prevent items from sticking together, and is mostly used in the electronic industry.
