Dimethyl Phthalate (DMP), CAS No. 131-11-3, is a colorless, transparent oily liquid with a slight aromatic odor. It is miscible with ethanol and ether, and soluble in benzene, acetone, and other organic solvents, making it a versatile chemical in industrial applications. In addition, as a plasticizer, people widely use DMP in the production of resins, cellulose resins, rubber, and vinyl resins.
What is Dimethyl Phthalate Used For?
DMP has broad applications, particularly as a plasticizer for resins and polymers. It is essential in plastic production, especially in cellulose acetate films, varnishes, transparent papers, and molding powders. Additionally, manufacturers widely use DMP as a solvent for mosquito repellents, insecticides like DDT, and in the production of nitrocellulose. Its versatility makes it suitable for various industries, and it is also employed in gas chromatography as a fixative. Buyers seeking high-quality Dimethyl Phthalate for plastic production or insect repellent formulations can buy Dimethyl Phthalate online from Integratechem, a trusted supplier.

Benefits of Dimethyl Phthalate in Polymers
DMP provides significant advantages when used in polymer production. It improves the flexibility and durability of materials, making them more resilient to low temperatures and environmental stress. In addition, Manufacturers often combined DMP with other plasticizers to reduce high volatility and prevent crystallization at low temperatures.
How to Replace Dimethyl Phthalate in Polymers
With growing regulatory pressure and environmental concerns, manufacturers are exploring alternative plasticizers to replace DMP in certain polymer applications. Bio-based plasticizers, such as Acetyl Tributyl Citrate (ATBC) and Diethyl Phthalate (DEP), are becoming popular substitutes due to their lower toxicity and environmentally friendly profiles.
Packaging, Storage, and Transport
Packed in iron drums of 230 kg/barrel. Stored in a cool, dry, and well-ventilated area away from moisture and ignition sources. To ensure safe handling, you should strictly follow the proper storage and transportation guidelines outlined in the DMP safety data sheet (SDS).
