"Poly bd™ "is a hydroxyl terminated liquid Poly butadiene polymer.
Same as other polyols,
Poly bd™ has a highly reactive hydroxyl group. Poly bd™ (Poly butadiene type) is able to cure as Polyurethane elastomer with various isocyanates. By the difference in molecular weight, there are two grades of R-15HT and R-45HT in Poly bd™ .
We also have "Poly ip™ "(Poly isoprene type), and "EPOL™ "(Poly olefin type).
Either glade has high-hydrolysis resistant main chain.
That make you easy to design High-Hydrolysis resistant materials.
