  • Applications

    2-Ethylhexyl butyl phthalate (CAS 85-69-8) is primarily used as a plasticizer for polyvinyl chloride (PVC) polymers to impart flexibility in flexible PVC products such as flooring, cable insulation, films and coatings, and synthetic leather; it is also employed as a plasticizer in coatings, inks, and adhesives to improve film-forming properties and elasticity; in electronics manufacturing, it supports flexible PVC insulation and protective coatings for cables; and in polymer formulations it can act as a processing aid to facilitate compounding and processing of PVC and related polymers.
