Product Specification

20 μm Clear PET fluorosilicone coated release film, excellent release property, resistance to oils, solvents, chemicals

PET fluorosilicone coated release film finds its application in a variety of industries including packaging, labeling, medical, automotive, and electronics due to its excellent release properties, as well as its resistance to oils, solvents, and chemicals.

Here are the main differences between PET fluorosilicone coated film and normal PET silicone coated film:

1. Release Properties:

PET fluorosilicone coated film has superior release properties as compared to normal PET silicone coated film.The fluorosilicone coating provides a low coefficient of friction and offers exceptional release performance with a wide range of adhesives, even in high-temperature and high-humidity environments.

2. Chemical Resistance:

Fluorosilicone coatings have superior chemical resistance than silicone coatings. PET fluorosilicone coated film provides excellent resistance to oils, solvents, and chemicals, making it an ideal choice for applications that require resistance to harsh chemical environments.

3. Temperature Resistance:

PET fluorosilicone coated film offers a wider temperature range of resistance than normal PET silicone coated film. The fluorosilicone coating provides excellent performance in high-temperature and high-humidity environments, making it ideal for applications in the automotive and

electronics industries.

4. Adhesion Properties:

PET fluorosilicone coated film provides excellent adhesion to a wide range of substrates, including plastics, metals, and glass. It also has a good

bonding strength with adhesives, making it suitable for applications that require good adhesion performance.

Fluorosilicone release film is used to isolate and protect items with adhesives, such as silicone and PI tapes. During production, storage, or transportation, the fluorine release film protects the adhesive from contamination and spoiling. The most commonly used applications are as a carrier for adhesive tapes or adhesives. The principle behind the use of the fluorine release film is the same as that of a release liner, mainly to prevent sticking. The primary difference is that fluorine in the fluorine release film exists in the form of fluoride. Most tapes are in the form of base plus adhesive, with the base material for high-temperature tape having different varieties (PET and polyimide). The temperature resistance of acrylic adhesive cannot match that of silicone adhesive. The silicone-based adhesive of the fluorine release film belongs to the same category as silicone oil release film and will become permanently adhered over time.

The general application scenarios of  20-micron PET fluorosilicone coated release film include:

1. Adhesive Labels and Stickers: The 20-micron clear PET fluorosilicone coated release film is commonly employed as a liner material for adhesive labels and stickers. Its transparent appearance allows for easy visibility of the printed or written information, while the fluorosilicone coating ensures smooth and effortless release of the adhesive. This film is particularly suitable when a clear and low-profile liner is desired.

2. Surface Protection and Preservation: The film finds application as a protective layer for various surfaces, such as glass, metal, or painted finishes. It acts as a barrier against scratches, abrasions, and dust, preserving the pristine condition of the surface. The clear PET fluorosilicone coated release film allows for uninterrupted visibility and inspection of the protected surface.

3. Electronics and Optical Applications: In the electronics and optical industries, the 20-micron clear PET fluorosilicone coated release film is utilized to protect sensitive components, displays, or lenses. It acts as a shield against dust, fingerprints, and minor impacts, ensuring optimal performance and clarity. The transparent film allows for unimpaired visibility and functionality.

4. Automotive and Aerospace Industries: The film serves in the automotive and aerospace sectors, particularly in surface protection during manufacturing, transportation, or assembly processes. It can safeguard sensitive areas, such as painted surfaces or polished parts, from scratches, debris, or chemical exposure. The clear PET fluorosilicone coated release film enables visual inspection and ensures the preserved quality of the surfaces.

5. DIY Projects and Crafts: The 20-micron clear PET fluorosilicone coated release film finds application in various do-it-yourself projects and crafts. It can be used for protecting artwork, photographs, or documents, providing a clear and protective layer against damage, moisture, or aging. The transparent film allows for appreciation and visibility of the preserved items.

It's important to note that the specific applications of the 20-micron clear PET fluorosilicone coated release film may vary depending on the manufacturer, industry requirements, and customization options available. Therefore, consulting with the supplier or manufacturer is recommended to determine the film's suitability for a particular application scenario.

Currently, the most widely used carrier is tape or adhesive products.

The application principle of fluorosilicone release film is similar to that of release film, mainly to prevent adhesion. However, it is not the same as silicone oil release film. Fluorine in fluorosilicone release film exists in the form of a fluoride compound. Most tapes exist in the form of substrate plus adhesive, and the substrate of high-temperature-resistant tapes varies greatly (PET, polyimide), and the temperature of acrylic adhesive cannot withstand the temperature of silicone adhesive. The adhesive of silicone is in the same category as silicones release film and will result in sticking after a long time of reaction. Fluorosilicone release film is mainly used for high-temperature adhesives, silicone double-sided adhesive bonding, gold finger, green glue, AB glue, 3M silicone adhesive bonding, etc. It can be processed into any other shape for special purposes by die-cutting.

The release force at room temperature is the size of the release force data obtained after standard testing at room temperature, with a unit of N/25mm, which can be converted into grams.

1. Release force less than 10 grams, i.e., 0.10N/25mm, is called light peel.
2. Release force less than 3-4 grams, i.e., 0.03-0.04N/25mm, commonly known as a very light release.
3. Release force less than 20 grams, i.e., 0.20N/25mm, is called medium release.
4. Release force of 35-45 grams, i.e., 0.35-0.45N/25mm, commonly known as heavy release.
5. Release force of 60-80 grams, i.e., 0.60-0.80N/25mm, commonly known as very heavy release.
6. There is also a Release force of 1.00N/25mm, which is above 100 grams, commonly known as super heavy release.

Residual adhesion rate refers to the force of fluorosilicone release film when it is peeled for the second time after the first peel, which is a data calculated for Teflon high-temperature tape.

Aging peel strength refers to the peel strength measured after a period of time or high temperature after fluorosilicone release film is used to bond products or tapes. Generally, the peel strength data obtained after aging is slightly larger than that obtained at room temperature.

Overall, 20-micron PET fluorosilicone release film's unique properties make it an ideal choice for applications where the release of silicone-based adhesives is required, particularly in high-temperature and harsh chemical environments.

The main feature of PET fluorosilicone coated release film is the superior release performance it offers, coupled with excellent chemical and temperature resistance. Its low coefficient of friction, coupled with the wide temperature range of resistance, makes it an ideal choice for demanding applications that require high-performance release properties.
