Polyester polyols
Polyester polyol is a type of polyol containing ester and hydroxyl groups and is produced in three types: aliphatic, aromatic, and semi-aromatic.
Since its inception, Kimiyagaran Pasargad Company has focused on the production of various polymers and has successfully produced and marketed various polyols in the categories of aromatic, semi-aromatic, and aliphatic with high diversity and functionality. The company's experience, knowledge, quality, and manufacturing technology speak for themselves.
This company produces a wide range of this substance with different chain structures, OH numbers, functionalities, molecular weights, and chemical natures with varying functionalities. We strive to create a masterpiece with every synthesis in our reactors.
This substance is used in rigid foams (panel, refrigeration, wood, spray, etc.), flexible foams (automotive, motorcycle seats, airplane, furniture, etc.), coatings, flooring, and adhesives. Additionally, aromatic polyesters are generally used for rigid applications, while aliphatics are used for flexible applications.
Polyester polyol is a hybrid polymer obtained from the reaction of a diol with a diacid. It exhibits various properties depending on different chain lengths and spatial configurations (linear or grafted), showcasing the wonders and beauty of chemistry.
Although the cost of these materials is lower than that of polyethers, making them a suitable substitute, they have their own strengths and weaknesses. Polyethers offer a wide range of functionalities with different hydroxyl numbers and longer chain lengths.
