We commonly use release paper, which is actually isolation paper, silicone oil paper, and anti stick paper. It is a type of anti stick paper that prevents the adhesion of prepreg and also protects the prepreg from pollution. There are many types of release paper, usually divided into plastic release paper and non plastic release paper. In addition, it can be divided into organic silicon release paper and non silicon release paper according to the release agent. So what conditions do we need to meet when making release paper?
1. Cleanliness of release paper: refers to the cleanliness and smoothness of the appearance. Because the working environment of release paper manufacturers is different, it is almost rare to be in a dust-free workspace. Generally, a better factory has great advantages in environmental protection and environmental protection, as these can affect cleanliness. Many release paper cleanliness is not contaminated during the production process. It is largely due to the low cleanliness of the slitting manufacturer during slitting, which leads to electrostatic adsorption and the emergence of dust;
2. It should be able to adhere to the prepreg, but it should be easy to separate the two;
3. Peeling force of release paper: Peeling force refers to whether the product can be easily torn off, which is a strict testing procedure. Small slitting machines are currently mainly used internationally according to national standards. The unit of peeling force is grams. According to the different test results, it is generally divided into three procedures: light release, medium release, and heavy release. Light release refers to the ability to easily peel off when the release paper and tape protective film are attached, while medium release is not easy to peel off, while heavy release is not easy to peel off.
