CA-20 is made of natural high quality gypsum ore, which is calcined
in high temperature, then removing impurities, ultrafine grinding,
and air separation processing.
CA-20 is an anhydrous calcium sulfate with bright white color,
strong hiding power, good coloring and easy spread. The brightness
is 98% minimum, whiteness is 97% minimum. CA-20 can replace 20-40%
costly titanium dioxide in different industry andcan replace USG CAS-20™-4 completely.
(1)Extend costly titanium dioxide used as white pigment in paper
coating and coating industries and plastics applications.
(2)As food packaging and food acid-resisting fillers, is suitable
for microwave oven boxes and other special requirements in high
temperature, acid and alkali resistance environment.
(3)In HDPE, HIPS products, after using calcium sulfate partly
replace titanium dioxide, the impact of whiteness, opacity and
mechanical properties is very small.
