Low Molecular Weight PET Polyether

Performance & Application:

● It is liquid at room temperature, so it is easy to use and process. The glass transition temperature is -80℃ with excellent low temperature properties. The mechanical properties of its elastomer products are close to PTMG, and can replace PTMG in harsh low temperature environment.

● Due to its good molecular flexibility, it can replace PTMG in flexible artificial leather and ink; Can be used for low-temperature resistant adhesives, coatings, polyurethane elastomers, etc.
