1. Cleanliness: refers to the cleanliness and cleanliness of the surface, as the production environment of release film manufacturers is different, it is basically impossible to produce in a dust-free studio. Generally speaking, they are ordinary factories, and better ones will have many improvements in environmental protection and environment, which will have an impact on cleanliness. Many times, the cleanliness of the release film is not contaminated during the production process. Most of the time, it is due to electrostatic adsorption caused by the low cleanliness of the slitting manufacturer during slitting.

2. Peeling force: Peeling force refers to whether it is easy for a product to peel off. Of course, there are strict testing standards, and currently, national standards are mainly used in China. The unit of peeling force is grams, which can be divided into three standards according to different test results: light, medium, and heavy release. Light release refers to the easy peeling when the release film is attached to the tape or protective film, while medium release is general peeling, while heavy release is difficult to peel.

3. Moisture and temperature resistance. Silicone oil has a certain degree of temperature resistance, but it depends on the use of the product and the use of domestic and imported silicone oil. Normally, it can withstand around 150 degrees Celsius.
