Terate® 2541V

INVISTA offers a complete line of aromatic polyester polyols with a variety of functionalities and equivalent weights. This allows formulation flexibility in achieving the range of physical and flammability properties required of polyurethane and polyisocyanurate foams. These polyols are based on co-products derived from the production of dimethyl terephthalate (DMT), which gives them high aromaticity.
