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
