This film is often made of some variety, cousin, or neighbor of the Teflon family. It's non-stick, usually temperature resistant, and can also be permeable so that in spite of its solid appearance, it still breathes. Cool, huh? |
Release film can be had either solid (no holes) or perforated (guess).
If it's solid, then the intent is to provide a barrier so that resins do not escape from the part during cure.
Perforated films do the opposite. They allow for some resin to escape during the cure.
How to Choose a Release Film:
1. Temperature. What is the cure temperature of the resin system being used?
2. Complexity. Is the part all kinds of curvy, or is it flat? Yeah, we know. High tech? So would yo u prefer we use the terms simple curve or compound curve? If it makes you happy...
3. Chemical resistance. Some resin systems are picky. We should talk if this is a concern. |
