Synthetic Polymer Wax (Solid Type): ST100 Synthetic Polymer Wax

Basic Information

ST100 is an acrylic polymer developed using Nippon Shokubai’s proprietary polymerization technology. In addition to the general properties of wax, ST100 is a solid, white polymer, with a high molecular weight and the features listed below.
ST100 has an extremely high molecular weight compared to general waxes. It has sharp thermal fusion properties and is highly soluble in aromatic and aliphatic solvents.
