Eastman TXIB™ Formulation Additive


Last updated:

Eastman TXIB™ Formulation
Additive is the lowest viscosity (9 cps) additive available to the flexible PVC industry. Eastman TXIB™ Formulation Additive is completely compatible with PVC in all proportions and is usually blended with general-purpose plasticizers such as DOP or DOTP. The unique low viscosity makes this material particularly suitable for PVC plastisols and often allows adding additional fillers to the plastisol, resulting in a cost savings.

Eastman TXIB™ Formulation Additive has efficiency generally equal to DOP, which makes substitution in a vinyl formulation very easy. It imparts a dry surface to the vinyl, excellent resistance to staining, and physical properties equivalent to DOP. Eastman TXIB™ Formulation Additive is also used in inks, coatings, urethane elastomers, and nail polish lacquers.
