It is liquid at room temperature, which is convenient to use and process. Glass transition temperature of -80 ℃, with excellent low-temperature performance, the mechanical properties of the elastomer are close to those of PTMG.
Mainly used in solid propellant formulations, with excellent low-temperature mechanical properties and a wide range of operating temperatures.
With good molecular flexibility, it can replace PTMG in flexible artificial leather and printing ink; it can be used in low-temperature-resistant adhesives, coatings, polyurethane elastomers and so on.
