Alcoa Hydral products are specially
precipitated aluminum trihydroxides.
They are ultra-fine, crystalline,
organic-free, pure white powders.
offers similar chemical and physical
properties as the Hydral products.
Hydral PGA is Hydral 710 that has
been spray dried in the presence of
a dispersant. Spray drying increases
the bulk density and improves flow
characteristics for better handling
and bulk shipping.
This product can be tailored for
specific applications. It displays
outstanding flame-retardant and
smoke-suppressant properties for
thermoset and thermoplastics as
well as elastomeric copolymers. It is particularly useful as filler and
coating pigment for fine printing
papers for increased brightness,
smoothness, and opacity.
In coating applications, Hydral is used to
impart brightness and gloss for annual report
stock and paperboard. It has the added benefit
of providing high ink receptivity.
