Refractive index

[mistabbrn]

I am looking for a table that provides the refractive index and other optical properties for a variety of optically clear plastics like PMMA.

 

[patprimmer]

have you tried matweb

Have you tried the raw materials suppliers

What the heck, I had it at hand

From Data it is

1.5 for acrylic.

1.59 for PC.

1.58 for PET.

1.46 for TPX.

1.60 for Styrene.

1.53 to 1.58 for PVC.

From memory

Acrylic has the lowest haze factor and the highest transmission, with transmission being over 90%

PC comes at around 85%

PVC will be worse than PC.

PET is probably about the same as PC.

I don't have data for cellulosics or Polyurethanes.

There are LOTS of places on the web to find this sort of thing:

Mind telling us why you want the data? We'd be better able to help then.

You can find all the data you need in the Polymer Handbook for example.

There is not any memory with less satisfaction than the memory of some temptation we resisted.
