Product Description:
Boltorn™ Premium H20 is a hyperbranched polyester based on bis-MPA offering a high extent of hydroxyl surface groups. Boltorn™ Premium H40 has an average of 64 hydroxyl groups and can be used as a precurser for dendritic-linear macromolecules, surface modification and as a cross-linker for thermosets, amongst other applications.

Polymer Factory's Boltorn™ Premium H40 has been subjected to additional purification steps to remove low molecular mass fractions and moisture, providing the material as powdered solid.
