Antimony Trioxide
The antimony trioxide samples were all "opaque," except for the 1% loaded sample, which was rated "slightly translucent." The differences in opacity translate into large savings in colorant costs for the antimony pentoxide FR, the researchers concluded. The less-opaque PP produced with this additive reportedly required only about one ...
