25 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 25-micron PET
fluorosilicone coated release film include:
Adhesive Labels and Tapes: The 25-micron clear PET fluorosilicone coated release film is commonly used as a liner material for adhesive labels and tapes. Its clear appearance allows for visibility of the underlying printed or written information, while the fluorosilicone coating ensures easy release of the adhesive. This film is particularly suitable for applications where a transparent liner is desired.
Protective Films: The film finds application as a protective layer in various industries. It can be used to safeguard surfaces, such as glass, metal, or electronics, from scratches, dust, or other damage during transportation, storage, or assembly processes. The clear nature of the film allows for visibility and inspection of the protected surface.
Surface Protection in Manufacturing: The 25-micron clear PET fluorosilicone coated release film is utilized in manufacturing processes to protect sensitive surfaces from contamination or damage. It can be applied to components or products during machining, painting, or assembly operations, ensuring that the surface remains pristine until final use. The clear film allows for easy visual inspection.
Graphic Overlays and Membrane Switches: In the production of graphic overlays and membrane switches, the film serves as a protective layer. By applying the clear PET fluorosilicone coated release film, the graphics, symbols, or buttons can be shielded from wear, chemicals, or environmental factors, ensuring longevity and durability. The clear film retains the visibility and readability of the underlying graphics.
Electronics and Display Applications: The film is employed in the electronics industry for protecting displays, touch screens, or sensitive electronic components. It acts as a barrier against scratches, fingerprints, or dust, maintaining the clarity and functionality of the electronic device. The clear PET fluorosilicone coated release film allows for optimal visibility and touchscreen sensitivity.
It's important to note that the specific applications of the
25-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.
Overall, 25-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.
