Expert Skip Thacker,responds as follows.

Tushan's formulation, containing a fairly high level of filler, inherently will not be very glossy----perhaps a little (1-2 phr) K-120N acrylic process aid may help--it does for rigid PVC. Usually a little higher heat in the last die zone of profile extrusion will give added gloss. Otherwise, reduce filler level.
