Blending special bioabsorbable polyphosphate fillers, biodegradable soy protein isolate, plasticizer, and adhesion promoter in a high-shear mixer followed by compression molding resulted in a relatively water-resistant, biodegradable soy-protein polymer composite.

Atomise Polymers to Maximise Profits
The difficulties of mass-producing micron-sized high-quality powders from molten polymers can be avoided by using high pressure gas atomisation methods.
