Documented Uses

• Used as plasticizer for nitrocellulose, ethyl cellulose, chlorinated rubber, polyvinyl acetate, polyvinyl chloride, and other polymers; Also used as a heat sealer for cellulose, in paper finishes, and to make printers ink water-resistant; [HSDB]
• Pulp and Paper Processing [Category: Industry]
• Plasticizer for nitrocellulose, ethyl cellulose, chlorinated rubber, polyvinyl acetate, polyvinyl chloride, and other polymers.
• Dicyclohexyl phthalate is used as a plasticizer to modify the properties of synthetic resins, in alkyd resins and cellulose nitrate to increase their stability to light and weathering, and to improve the chemical and physical properties of plastics by preventing creep. It is very stable to heat and light and imparts a glossy finish to extruded materials. It is also used in paper finishes and makes printers ink water-resistant.
