Overview: REEPLUS functional release film is a formed peel film with functions such as covering, filling, release, buffering, etc. It can replace similar imported products from the United States. Specially designed for the hot pressing process of soft and hard bonding boards, FPC flexible circuit boards, PCB printed circuit boards, and high and low order difference circuit boards. The REEPLUS functional release film provides stable and controllable advantages in the hot pressing process for circuit board lamination. Advantages of pressing process 1. Effectively solving the problem of "board surface swelling and shrinkage" REEPLUS functional release film "locks" around the pressing parts, thereby reducing the damage caused by heat and pressure

Each product has its own advantages in existence, but although some products are the same in nature, their existence also varies due to their different types and specifications. 1、 The advantages of TPX gel barrier release film are more extensive: 1. Good heat resistance: it can also be used at high temperatures of 200 ℃. The melting point of TPX gel barrier release film is around 230 degrees Celsius, and it can also be used in process procedures at 200 degrees Celsius. 2. Excellent demolding performance: It can peel off various materials with low surface tension, and has excellent demolding performance for various materials such as epoxy resin. 3. Good filling ability: can be used with complex

The main factors affecting the appearance quality of non silicon release film of pet are as follows: 1. Coating head At present, the coating head widely used by silicon coating enterprises in China mainly includes scraper/Anilox/roller coating/multi roller coating. Just slightly improve the appearance and performance. Essentially, improvements should not exceed 20%. However, foreign countries use micro forming rollers with a certain angle for coating, which improves transparency from an optical perspective. Meanwhile, the possibility of rainbow lines has been completely eliminated. 2. Composition of coating agent formula Currently, the product commonly known as 120 # solvent oil is widely used in silicon coating enterprises in China, but from the perspective of non silicon release films used in coatings, it is better

What is the quality and durability of PET release film? Many factories like to use practical materials, so that they can efficiently complete and ensure quality. At this point, many factories choose high-quality and durable PET release films. Nowadays, people are increasingly paying attention to PET release membranes, and many inevitably ask, what are the advantages of PET release membranes? This article is explained by the editor of Ruichangxing Film PET Release Film Manufacturer. 1. The constituent material PET release film is made of heat shrink polyester film. The characteristic of this heat shrinkable polyester film is that it is stable at room temperature and remains at a glassy ultra-high temperature for shrinkage.

1. The Tg value of TPX release film is only 10-30 ℃. At high loads, its HDT is lower, but due to its melting point (Tm) reaching 220-240 ℃, it exhibits HDT at low or no loads. The softening point of Vicat is 140-180 ℃, which is equivalent to PC or PSu. b. The thermal life of TPX release film is determined by temperature and time. Aging in the air is caused by oxidation reactions. To prevent oxidation reactions, heat-resistant stabilizers can be added, which can extend the heat-resistant life by about three times. In UL specifications (UL

The TPX release membrane has the best resistance among transparent resins. Transparent materials are generally non crystalline (such as glass, PS) or fully crystalline (such as diamonds, ice). The TPX release film is a crystalline polymer with a crystallinity of 20-70%, making it highly transparent due to its almost identical density between the crystalline and amorphous parts, demonstrating optical homogeneity. The difference in mechanical properties between amorphous materials and crystalline materials is that amorphous materials lose strength above the Tg point, but crystalline materials retain mechanical strength before the far crystallization melting point, and do not lose strength above the Tg point. T of TPX release film

The TPX release film can be formed by injection, extrusion, and blowing methods, but rotary forming or powder coating are difficult. Basically, it is a material with good fluidity and can be formed using the same molding method and equipment as PE and PP. As it is a transparent material, if other materials are mixed in, it will significantly reduce transparency. When dyeing, dry mixing method can be used, but pigments must be selected that can withstand molding and processing temperatures. The extruded products of TPX release film, such as films, coated paper, tubes, round rods, etc., are widely used in frozen food packaging, release paper, baking corrugated paper, and release paper for epoxy resin hardening. Used for PE or PP

The injection molding of TPX release film of molding machine can be used with a molding machine for polyolefin with appropriate heating capacity and temperature control mechanism. Wide molding temperature range, can be formed between 270-330 ℃, with small internal deformation

PET release film uses PET as the substrate for the release film and is coated with a layer of silicone oil, hence it is commonly referred to as a silicone oil film. Reliable quality PET release films can be classified into different types, such as hot and cold tearing and matte surfaces caused by different processes. So what is the excellent performance of PET release film? Below, the editor from the PET release film manufacturer of Ruichangxing Company will provide a detailed explanation for everyone. 1、 Excellent antistatic performance Because PET release film is usually used in the electronic industry, electronic products have strong resistance to Electrostatics. Therefore, in order to meet this demand, the production process will add

The quality control of high-temperature release film is a concern for all manufacturers, and quality control is a challenge, which is the competitiveness of a manufacturer. Today we have summarized the six key issues for quality control. 1. Do not easily clarify the process, do not easily change the quality issues of the high-temperature release film, and identify the root cause, main factors, or main manifestations of the problem; Changing the process easily before clarifying the problem actually masks the true cause and problem. 2. The process control should have a strong concept of quantification and traceability. The quality of high-temperature release film depends on many factors, and no details should be overlooked; Try to use data for any details

1. Fluorine release film is not prone to chemical reactions, has good temperature and humidity resistance, moisture-proof and oil-proof, and plays a role in product isolation; 2. Good high-temperature resistance, smoothness, and strength; 3. It can prevent the adhesion of the prepreg and protect the prepreg from contamination; 4. Release paper can adhere to the prepreg, but it is easy to separate the two and has sufficient density to prevent water from entering the prepreg through it. The properties of fluorine release membranes are: 1. The colors are generally transparent and milky white. 2. There is no migration phenomenon, except for the danger of silicone release film transferring to the material it is tightly attached to. 3. Controllable release force, high glossiness, and cleanliness
