1,3-propanediol (1,3-PDO) is colorless, Odorless, transparent and viscous liquid, hygroscopic, miscible with water, alcohol and various organic solvents. It is an important organic chemical raw material, mainly used in inks, coatings, cosmetics, pharmaceuticals, antifreeze and other industries.
The application of 1,3 propylene glycol in polyester plasticizers:
Polyesters developed with 1.3 propylene glycol are usually used as liquid plasticizers and powders The resin may be mixed with vinyl resin and rubber. As a polyester plasticizer with excellent polymer properties, its overall performance is better than that of monomer plasticizers. It can be used alone as a sol plasticizer in resin components or in conventional combination with plasticizers.
The polyester plasticizer developed with 1.3 propylene glycol has excellent plasticizing properties in rubber, plastics and other materials. It is a new green plasticizer product with excellent comprehensive performance that can replace DOP, especially Suitable for the development of green plasticizers for biodegradable plastics. Food packaging materials are a huge market, and using green polyester plasticizers as additives for synthetic materials will have a broader market development space.
