| Plaster takes four different forms, including
hemihydrate gypsum (which is often used as a formative material),
depending on the water content in the crystals. The individual forms
have their own features and are widely used as additive materials
such as food additives, resin fillers, trace water content removing
agents, construction materials, etc. |

Drying agent
Moisture absorption preventive
Functional adulterant
Filler |
| >Dihydrate gypsum calcium sulfate
T-Gou |
 |
This product complies with the Japanese Standards
for Food Additives. It does not exhibit hygroscopic properties
but low hardness (Mohs hardness: 1), being widely used as food
additives and fillers in a number of fields.
|
| >Hemihydrate gypsum FT-6,T-17 |
|
These products are made by firing carefully selected
materials. They exhibit a water absorbing property (water adsorption)
resulting from the transition to dihydrate gypsum,
being used as dehydrating agents and fillers in a number of fields.
|
| >Type III anhydrous gypsum D-1 |
 |
These products are made by firing carefully selected
materials at high temperatures. It exhibits very strong hygroscopicity
(instantaneous adsorption of moisture in the atmosphere) resulting
from the transition to hemihydrate gypsum, being used as dehydrating
agents and drying agents for paints and resins, and fillers in
a number of fields.
|
| >Type II anhydrous gypsum D-101A |
 |
These products are made by firing carefully selected
materials at high temperatures. It exhibits no hygroscopicity
and hydration setting characteristics; however, because of the
absence of crystallization water, it is used as fillers for heat-resistant
engineering plastics and other applications in a number of fields.

| Note: What is a water absorbing property? :It
means the capability of absorbing water (water drops). What is hygroscopicity
(dehydrating property)? :It means the capability of adsorbing moisture
in the atmosphere. |
