C08K Use of inorganic or non-macromolecular organic substances as compounding ingredients (paints, inks, varnishes, dyes, polishes, adhesives C09)
Description
C08K covers the incorporation of inorganic or non-macromolecular organic additives into macromolecular compound formulations, including fillers, reinforcing agents, plasticizers, colorants, and processing aids. This subclass addresses how these low-molecular-weight or mineral substances modify the properties of polymers and elastomers during compounding or formulation. The classification encompasses additives for improving mechanical strength, flexibility, thermal stability, electrical conductivity, and aesthetic properties of plastic and rubber compositions. C08K excludes the additives themselves (which fall under their respective chemical classes) and focuses specifically on their use and effect within macromolecular systems.
