C10H10O4
131-11-3
Dimethyl phthalate is a plasticizer with strong solubility for a variety of resins. It can be compatible with a variety of cellulose resins, natural rubber and synthetic rubber, and vinyl resins. It has good film-forming, adhesive and Waterproof, light and thermal stability are also high.
Dimethyl phthalate is a colorless transparent oily liquid with a slight aromatic taste. It can be miscible with organic solvents such as ethanol, ether, acetone, cyclohexanone, methyl ethyl ketone, methanol, n-butanol, toluene, and is insoluble in water and petroleum. ether.
Application:
Dimethyl phthalate is a plasticizer with strong solubility for a variety of resins. It can be compatible with a variety of cellulose resins, natural rubber and synthetic rubber, and vinyl resins. It has good film-forming, adhesive and Waterproof, light and thermal stability are also high;
It is often used in the production of cellulose acetate film, varnish, transparent paper and molding powder in combination with diethyl phthalate. A small amount is used in the production of nitrocellulose. It can also be used as an increase in nitrile rubber. Plasticizer.
DMP can also be used as a solvent for mosquito repellent oil (crude oil), polyvinyl fluoride paint, methyl ethyl ketone peroxide and DDT. When used as a rubber plasticizer, it has no effect on rubber vulcanization and the product has good cold resistance.
