The difference between clear PET thermal cured silicone coated release film and clear PET UV cured silicone coated release film mainly

lies in the way they are cured, which affects their properties, applications, and processing conditions. Here are the key differences between

the two types of silicone coated release film:

1. Curing method:

    Clear PET thermal cured silicone coated release film is cured using a thermal curing process, which applies heat to initiate the cross-

    linking of the silicone coating to the PET film. Clear PET UV cured silicone coated release film is cured using UV radiation, which initiates

    a photochemical reaction that cross-links the silicone coating to the PET film.

2. Processing conditions:

    The processing conditions for clear PET thermal cured silicone coated release film and clear PET UV cured silicone coated release film

    are different. Thermal curing requires high temperatures, which can limit the types of substrates that can be used. UV curing, on the other hand,

    requires lower processing temperatures and can cure a wider range of substrates.

3. Properties:

    Clear PET thermal cured silicone coated release film has better dimensional stability and higher temperature resistance compared to clear

    PET UV cured silicone coated release film. It also has a longer shelf life and can be stored at room temperature for a more extended period 

    without affecting its performance. Clear PET UV cured silicone coated release film has excellent optical clarity and a lower tendency to

    yellow over time.

4. Applications:

    Clear PET thermal cured silicone coated release film is suitable for applications that require high-temperature resistance, dimensional stability,

    and long-term storage properties, such as medical packaging, industrial applications, and automotive industries. Clear PET UV cured silicone

    coated release film is suitable for applications requiring optical clarity, such as labels and graphics, and for applications that use more delicate 

    substrates.

The main differences between clear PET thermal cured silicone coated release film and clear PET UV cured silicone coated release film are the

curing method, processing conditions, properties, and applications. Factors such as substrate, temperature resistance, clarity, and storage 

properties should be considered when selecting the appropriate silicone coated release film for a specific application.

In tape applications, the most common curing method used for PET release film is UV curing. This is because UV curing offers faster curing times,

lower energy consumption, and greater flexibility in terms of substrates compared to thermal curing. UV curing also allows for higher throughput 

rates, making it suitable for high-volume production environments. However, there are certain kinds of tapes that require thermal curing of the

PET release film. For example, some high-temperature adhesive tapes require a PET release film that has been cured through a thermal process

to ensure that the film can withstand high temperatures without releasing the adhesive prematurely or degrading over time.

These types of tapes are mostly used in the automotive or electronics industry where high-temperature resistance is critical.

While UV curing is the most common method used in tape applications, there are some instances where thermal curing of the PET release

film may be required, particularly for high-temperature adhesive tapes. The choice of curing method depends on the specific requirements of the 

tape application, including adhesive properties, substrate, and processing conditions.

The trend in curing methods of PET silicone coating processes is toward electron-beam (EB) and UV (ultraviolet) curing processes, which are 

more environmentally friendly and energy-efficient than thermal curing processes. The shift to EB and UV curing is driven by several factors,

including:

1. Environmental concerns:

    Thermal curing requires high temperatures, which can generate pollutants and greenhouse gases. In contrast,

    EB and UV curing use less energy and produce fewer emissions.

2. Faster curing times:

    EB and UV curing offer faster curing times than thermal curing, which increases production efficiency and reduces costs.

3. Controllability:

    EB and UV curing offer finer control over the curing process, allowing manufacturers to tailor the properties of the coatings to

    specific applications.

4. Increased substrate compatibility:

    EB and UV curing can be used with a broader range of substrates than thermal curing, including temperature-sensitive materials.

5. Cost-effectiveness:

    The investment cost of EB and UV curing equipment has dropped in recent years, making them more accessible and cost-effective for 

    manufacturers.

As the demand for more energy-efficient and environmentally friendly manufacturing processes continues to grow, we can expect to see an

increased adoption of EB and UV curing methods in the PET silicone coating process. While thermal curing is still widely used, the advantages

of EB and UV curing are likely to make them the preferred method for many applications in the future.
