OCA foam graphite heat sink diffusion sheet PET mesh protective film

PET mesh protective filmIt is formed by using polyester film as the substrate, applying acrylic ester adhesive on one side of the raw material through a coating machine, and then winding it up. There are neatly arranged mesh patterns on the surface of PET mesh protective film, and the thickness of the protective film varies from 30um to 130um. Viscosity is divided into ultra-low viscosity, low viscosity, medium viscosity, medium high viscosity, and high viscosity. The thickness and viscosity of the PET mesh protective film are selected according to the different bonding materials.

1. High compatibility and wide range of applications, multiple materials can use the same protective film.

2. High cleanliness can reduce material damage.

3. The circular structure can disperse pressure and reduce the probability of impurities and crystal dots directly causing damage.

4. Easy to adhere, easy to peel off, can improve the efficiency of automated assembly, and reduce the defect rate.

5. There is an automatic exhaust bubble function, and when inspecting the product, the protective film can be restored to achieve the same effect as the equipment.

The use of PET mesh protective film: OCA、 Used in die-cutting processes such as foam, graphite heat sinks, diffusion sheets, etc.

During the production process of PET mesh protective film, it is necessary to keep the production workshop clean and tidy. Production needs to be carried out in a dust-free workshop, and workers must wear dust-free clothing according to strict requirements to ensure the cleanliness and quality reliability of the protective film during the production process.

1. The surface layer of polyester film prepared by corona discharge;

2. Apply adhesive onto the corona surface of polyester film using a coating machine, and then feed the coated polyester film into an electric oven;

3. Immediately fold the PET film in the electric oven into a mother roll;

4. Number the rolled mother coil and send it to the curing chamber for solidification;

5. The cured mother roll is sent to a multi axis laminating machine according to the first in first out method standard for double-layer lamination. During lamination, the polyester film is first laid on the mother roll without bubbles, and then another polyester film is attached to the bubble free polyester film and repeatedly bonded.

1. The optimal storage temperature is between 22-28 ℃ and a relative humidity of 50% -70%;

2. Avoid direct sunlight and storage under high temperature (above 40 ℃) and high humidity (above 70% RH) conditions;

3. It is recommended that users use the product within six months from the date of production (with a shelf life of six months);

4. Ensure that the surface of the object being adhered to is dry, clean, and free of any oil stains before applying this product.
