UV transmission by PC without UV inhibitor

UV transmission by PC without UV inhibitor

UV transmission by PC without UV inhibitor

(OP)
Does anyone know what kind of UV transmission can be expected from a piece of polycarbonate that does not have a UV inhibitor?
Any information or advice on where to find an answer would be great.
Thanks

RE: UV transmission by PC without UV inhibitor

This shows a spectrum. It doesn't say if the PC is stabilized but that shouldn't change the spectrum because the typical stabilizers are aromatic just like the polycarbonate is. An aliphatic polycarbonate would look very different though (lacks the aromatic band around 200nm).

Bayer used to produce such grahs in their literature on the application of PC for transparent roof sheeting. A google seach on Makrolon may show some results.
