In an academic project, I need to protect some electronics components from heat (around 85 °C). I am searching for both a cheap plastic film and a cheap plastic to be used in a injection molding process.
As matt_black referred, the main criteria of the selection is "the point where structural integrity is reduced by repeated use at that temperature or the point where the polymer starts to creep".
By now I am using cork, but I would like to use a more robust material.
Those materials should be both thermal and electrical insulators and should not absorb water. They should also be resistant to the external environment: rain, sun (UV radiation), dust, etc.
Which materials are the best option in this case? From what I have searched, these are the main options in terms of thermal requirements:
- PPO/PPE based
- ABS and SAN
- ABS/Polycarbonate alloy
- Polyethylene and copolymers
