1,3propanediol (1,3PDO) is a colorless, tasteless, transparent and viscous liquid, which is hygroscopic and miscible with water, alcohol and a variety of organic solvents. It is an important organic chemical raw material, mainly used in printing ink, coatings, cosmetics, pharmaceuticals, antifreeze and other industries.

Application of 1,3 propylene glycol in polyester plasticizer:

Polyester developed with 1.3 propylene glycol is usually used as a liquid plasticizer and mixed with powder resin or vinyl resin and rubber. As a polyester plasticizer with excellent polymer performance, its comprehensive performance is superior to that of monomer plasticizer. It can be used alone as a sol plasticizer in the resin composition or in combination with the plasticizer in a conventional way.

The polyester plasticizer developed with 1.3 propylene glycol has excellent plasticizing performance in rubber, plastics and other materials. It is a new green plasticizer with excellent comprehensive performance to replace DOP, especially suitable for developing green plasticizers for biodegradable plastics. Food packaging materials are a huge market, and the use of green polyester plasticizers as additives for synthetic materials will have a broader market development space.
