Today, the editor of Ruichangxing release film manufacturer will briefly introduce the performance characteristics of silicone oil release films, hoping to be helpful to everyone. First of all, let's have a comprehensive understanding of silicone oil, which is also called dimethyl silicone oil. Silicon oil is short for silicone oil, which is the general name for a series of low molecular weight polydi Methoxy group siloxanes with different viscosities. The scope of use of silicone oil is very extensive, such as in the pharmaceutical manufacturing industry, machine manufacturing and production industry, where this substance is more or less used. In the protective film packaging industry, silicone oil is also used on release films to achieve release effect and produce different release forces with more oil coating. Silicone oil is colorless or

You still need to have a good understanding of the basic knowledge of PET blue release film, so let's take a look with the editor of Ruichangxing release film manufacturer! Polyester heat shrink film is a new type of heat shrink packaging material. Due to its easy recycling, non-toxic, odorless, good mechanical properties, and environmental protection, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrink films in developed countries. However, ordinary polyester is a crystalline polymer, and ordinary PET film can only achieve a thermal shrinkage rate of less than 30% after special processing. To achieve higher thermal shrinkage

We are a professional coating manufacturer for release film. We would like to introduce several coating methods for release film. The coating process for release film generally includes the following three methods. Each manufacturer can choose the appropriate method for production according to their actual needs. Do you want to know which ones are? So now let's learn about the similarities and differences among the three methods, and what are their advantages? 1、 Scraper type coating: Scraper type coating often results in uneven gluing. PET release film manufacturers are mainly related to the processing accuracy of the scraper, the installation method of the scraper, the angle between the scraper and the backing wheel during coating, and the viscosity of the coating. The flatness accuracy of the scraper requires high precision

Ruichangxing Technology Co., Ltd. is a company that relies on quality for survival. The company conscientiously produces high-quality adjustable release film, with positive quality and high-quality service, which is trustworthy. The following are the characteristics of silicone oil release films compiled by Ruichangxing Company's release film manufacturers: Silicone oil film, also known as silicone oil release film, is to apply a layer of silicone oil on the surface of the film to reduce the adhesion of the film surface and achieve release effect. Release film is a commonly used material in heat transfer printing, with the substrate being PET, which is coated with silicone oil and is also known as silicone oil release film. Structure: The release paper has three layers of structure, the first layer is the base paper, the second layer is the coating, and the third layer is silicone oil, with a conventional thickness of 25

The selection principle of PET release film: Different surfaces require different stickiness. Similarly similar protective film surfaces may require different materials to have different stickiness. The subsequent processing steps are the key to determining viscosity. The subsequent processing of protective film generally includes bending, stamping, cutting, drilling, Thermoforming, etc. Reasonable combination of PET release film thickness and viscosity; The tensile strength and elongation of the protective film are to ensure that the flexibility and strength of the protective film meet the requirements. In addition, it is necessary to conduct sufficient testing on the quality and performance of PET release film to ensure that it can meet the usage requirements. PET release film is as easy to use as a tape. however

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
