High Functional Aromatic Polyester Polyols for PUR Systems

摘要

The transition to the next generation blowing agents has caused the Polyurethane industry to re-evaluate the necessity of polyester polyols in PU systems. The change to these novel blowing agents has caused diminished fire properties. This problem can be overcome by increasing polyester polyol levels. When attempting to introduce higher levels of polyester polyol, with current technology, the resulting system is inferior in terms of physical properties. In this paper the authors would like to introduce the next generation Terol polyols that will allow for greater loading of polyester in a system without sacrificing physical properties.
