Dimerized fatty acid based Thermoplastic resin
Common Polyamide resin : Solid type "Tohmide"
Thermoplastic "Tohmide" are the polyamide that are solid at room temperature and uses biomass-derived polymerized fatty acids and diamines as the main raw materials.Some products soluble in organic solvents are used as binder for gravure and flexo inks because they have good adhesiveness and wettability with pigments.They are also used in hot melt adhesives, moldings, etc. due to its good adhesiveness, heat resistance, and electrical insulation.
