Regarding how to choose fluoride release film manufacturers, we first need to know what its functions are. In fact, there are two main points. The first is to prevent contamination of the prepreg, and to be able to draw lines on its surface, providing convenience. The second function is to prevent lateral cracking of unidirectional prepreg. So, what conditions should high-quality fluoride release membranes meet? Let's explore together.

Condition 1: It can adhere to the prepreg, but at the same time, it can easily separate the two.

Condition 2: No chemical reaction or contamination with the resin system. When the ambient temperature or humidity changes, the length and width of a good fluorine release film will not change, so as to avoid the wrinkling of the immersion material caused by the fluorine release film.

Condition three: It should have sufficient density to prevent water from entering the prepreg through it.

Condition 4: After being pulled, the elongation of the fluorine release membrane should be consistent with the fiber to prevent deformation or distortion of the prepreg during the preparation process due to asynchronous stretching.

Condition 5: The fluorine release film is made of paper coated with anti stick substances, and its model should be distinguished based on differences in material, thickness, and elongation.

In short, in the selection of fluoride release membranes, we should not blindly choose without any basis, but should have some basic knowledge. Have a rough understanding of the classification and characteristics of release films, so as to select the release film with suitable performance and price, and not waste funds on some poor quality release films. In addition, we should also know that in terms of selection, we should mainly consider production costs, quality, production procedures, and the characteristics of the prepared products.

Reechas is a high-tech enterprise founded in 2006 and headquartered in Shenzhen, China.
