36um Blue Fluorosilicone Release Liner Polyethylene Terephthalate PET Film

36 μm blue 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 36 μm blue PET fluorosilicone coated release film is a thinner variant of the film mentioned earlier, and it shares similar properties but in a thinner form factor. Here are some common application scenarios where the 36 μm blue PET fluorosilicone coated release film may be used:

1. Label and Graphic Industries: The thin film can be utilized as a liner material for pressure-sensitive adhesive labels, decals, and graphics. Its release properties allow for easy removal of the adhesive-backed materials during application, and the thinner gauge provides flexibility and conformability to curved surfaces.

2. Electronics Manufacturing: The film can be employed in the electronics industry for applications such as protecting delicate components during assembly or manufacturing processes. Its fluorosilicone coating provides a reliable release surface, and the thinner gauge allows for precise placement and adherence to intricate electronic parts.

3. Medical and Pharmaceutical Industries: The film can find application in medical and pharmaceutical fields where the release of adhesive-backed products or components is necessary. It can be used as a liner for medical tapes, dressings, or adhesive-backed devices, providing a thin and conformable release surface during application.

4. Die-Cutting and Stamping: The thin film can be utilized in die-cutting and stamping processes for various industries. It can serve as a release liner for die-cut parts or stamped components, ensuring easy removal and preventing sticking or damage during the manufacturing process.

5. Industrial Applications: The 36 μm blue PET fluorosilicone coated release film can be employed in various industrial applications that require a thin, durable, and releaseable material. This may include uses in gasket manufacturing, sealing, or any process that involves the use of adhesives or coatings.

It's important to note that while these application scenarios are common, the specific use of the 36 μm blue PET fluorosilicone coated release film may vary based on the requirements of the industry or customization options available from the manufacturer. Consulting with the supplier or manufacturer is advisable to ensure the film's suitability for a particular application.

A qualified fluorosilicone release film has a smooth, even surface with no defects such as particles or bubbles. The product has excellent physical mechanical properties, a small thickness tolerance, high transparency, low heat shrinkage, and good flexibility, among other advantages. It is suitable for the composite mold cutting of high-temperature organic silicone pressure-sensitive adhesive tapes and is easy to peel off after use. The main purpose of fluorosilicone or fluorine film is to isolate sticky objects such as silicone tape and PI tape. During production, storage, or transportation, fluorosilicone release film plays a role in protecting the adhesive from contamination and deterioration.

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, 36-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.
