IOR of plastics

[Gijs]

Does anyone know realistic properties of plastics like ABS, PS, PE, PP etc. with regard to reflections? I know that plastics also have some sort of fresnel reflection, but does it have a higher IOR than glass for example?

Plastic has 1.46 IOR if that can be of help to you.

Thanks, but I think I have one more question:

Is the index of refraction of a material always the same as index of reflection in real life?

In theory I quess it should be and of course the material in question must
be very pure/clean. Any dirt, finger prints, dust changes the
appearance of the material. I tend to use the IOR table for reference only
and change the material properties to what I think looks good.

Thanks jujubee, that's the most useful list I've seen so far.
