Which material has these properties?

Question

Physics

I am looking for a material with the following set of properties:

1. flexible
   
2. elastic
   
3. thickness up to 0.8 mm
   
4. sheet
   
5. color preferably white
   
6. opaque
   
7. non-conductive
   

In general, something like a film for a phone, only a little thicker. Or tell me a resource to search for material by properties.

Answer 1

google sheet plastic, there are thicknesses suitable for you (most likely among polypropylene).
for example, in shops for artists , but in special. offices dealing with plexiglass and plastic should be cheaper.

Answer 2

White painted metal, from which window sills are made. If the paint is not damaged, the current does not conduct.
