(OP)
Hi all,
I am looking please for some leads on inj moulding resins to use for small IR window. I know these are often molded in polycarbonate with a deep blue or deep purple dye.
I wonder........
- is there a better descriptive term for this type of colorising so that I can describe it for the folks mixing the masterbatch?
- alternatively, are there suppliers who hold this in-stock in small qty's? I've tried quite a few without success.
- the resin, could it be either PC or Acrylic?
The window is a typical IrDA port in an electronics package with a requirement to pass 85% over a 800 - 1000Nm range.

Colourmaster, Oldham.
Or
Hampton Colours (nr Stroud, Glos.)
They both do "unit packs" (to colour 25Kg) of pigments.
There are others I guess, but have only used these two.
