Poly-L 220-56 has a nominal molecular weight of 2000. Poly-L® polyether polyols are high quality propylene oxide based multi-functional polyols that contain very low levels of terminal unsaturation, monol.
Poly-L polyols are manufactured using an organometallic catalyst. With this method, polyols with very low levels of terminal unsaturation and monol content are produced. Consequently, polyurethanes with higher molecular weight can be made from Poly-L polyols. These Poly-L based polyurethanes have significant advantages in performance.
