Refraction number/density of Polyethylene?

[timxtreme]

I need to know the refraction number as well as the density of conventional Polyethylene PE (not HDPE), but i didn't find them anywhere. Can you help me?

Thanks

"Texloc refractive index of polymers" contains "n," no densities, but does make the distinction between HDPE and LDPE.
