This is made effective by adding 0.001 to 10 wt% weak acid salt such as aluminum stearate
. The result is increased melt stiffness, enabling large hollow structure molding.
Comments: Surface treated with aluminum stearate compounds, giving it water repellant properties.
INCI name: water (and) titanium dioxide (and) isodeceth-6 (and) oleth-10 (and) aluminum stearate (and) alumina (and) simethicone
Provides both precipitated and modified fusion-process metallic stearates: aluminum octoate, aluminum stearate
, barium stearate, calcium stearate, lithium stearate, magnesium stearate, sodium stearate, and zinc stearate (including clear melt, polymer, and granular types).
Christensen added aluminum stearate
, a water-soluble aluminum salt, to the resin and produced a nonhardened plastic rigid enough to be worked in automatic machines; and the alum casein scraps were easily reworkable, greatly reducing waste.
