DMBA Dimethylolbutanoic acid 2,2-Bis(hydroxymethyl) butyric Acid DMBA is a new Amyl carboxylic acid with two active hydroxyl methyl groups, so it can be used as synthesis of water-based polymer system which can be widely served in water based polyurethane, polyester and epoxy resin etc.
Hydroxyl-terminated liquid polybutadiene (hydroxybutadiene rubber, HTPB) is a liquid telechelic polymer and a new type of liquid rubber. It reacts with chain extenders and cross-linking agents at room temperature or high temperature to form a cured product with a three-dimensional network structure. The cured product has excellent mechanical properties, especially hydrolysis resistance, acid and alkali resistance, wear resistance, low temperature resistance and excellent electrical insulation properties.
