Latest Patents
Herbert Schrunner holds a patent for "Heat stabilizers containing hydrotalcite particles with specific zeta potentials that demonstrate improved processing and performance in molded vinyl compounds." This patent describes particulate solid heat stabilizer compositions for vinyl halide polymers, which consist of about 30% to 90% by weight hydrotalcite particles. These particles are characterized by a sigmoidal curve on a Cartesian coordinate plot of zeta potential (mV) versus pH. The curve features negative zeta potential values balanced against positive zeta potential values over a pH range, with an inflection point between a pH of about 3 and 6, representing the isoelectric point (IEP). The stabilizer compositions are designed to be free-flowing, storage-stable, and processable, allowing for effective blending with vinyl halide polymers to confer heat stabilizing effectiveness.
