Applications:
Dibutyl phthalate(DBP) used for main plasticizer for cellulosic resins and polyvinyl chloride,good solvent potency
and good compatibility,fine softening property,but less aging-duration and anti-wanter-extraction.DBP plasticizer
also used as plasticizer for polyvinyl acetate,alkyd resins,ethyl cellulose and rubbers.
