How to distinguish the quality of fluorine release film

1, the fluorine release film is made of paper coated with anti-stick substances, and its model should be distinguished according to the difference in material, thickness and elongation.

2, do not chemically react with the resin system or pollute the resin system. When the ambient temperature or humidity changes, the length and width of the good fluorin release film will not change, so as to avoid the immersion material wrinkling caused by the fluorin release film wrinkling.

3, it can stick to the prepreg, but at the same time it can easily separate the two.

4. It should be dense enough to prevent water from entering the prepreg through it.

5, the elongation of the fluorine release film after traction should be consistent with the fiber, in order to prevent the prepreg in the preparation process due to the draft is not synchronized caused by deformation or distortion.
