Light blocking material

[ddddarkbull]

What is the best light blocking plastic material which can block as much light as possible. The material can be as thin as 0.020" (or machined to this size). We used black plexiglass before but when it go down to this thickness, light start leak through.

One with a lot of carbon black in it.
