Latest Patents
Nagatomo holds a patent for a process for producing granules of a polyvinyl chloride resin for preparation of paste. This patent describes granules that comprise 10% by weight or less of components with diameters of 10 micrometers or smaller. Additionally, it specifies that the granules contain less than 0.5% by weight of oversized components after classification using a 149 micrometers standard sieve. The granules have a bulk density of 0.45 to 0.58 g/cm and produce a plastisol with less than 0.3% by weight of oversized components after classification using a 62 micrometers standard sieve. The plastisol is created by mixing 100 grams of the granules with 50 grams of dioctyl phthalate. The process involves spray-drying an aqueous dispersion of a vinyl chloride polymer obtained through emulsion polymerization or micro-suspension polymerization.
