What are cellulose esters?

Eastman cellulose esters for formulated products are versatile, biobased polymers designed to enable our customers to formulate higher-performing, quality products for many different industries and markets. They can help you achieve desired formulation and end-use attributes. Our cellulose esters provide a competitive edge in application by enabling higher production rates, as well as in the final product by eliminating defects and improving appearance.

Commercially available cellulose esters

Eastman cellulose esters are available in many formats, providing a wide range in use. The unique values they add in each application will depend on the problems the formulator is trying to solve. Common specific targets are drying times, antisag, flow and leveling, color and gloss control, rheology adjustments, and controlled release. Cellulose esters do not contribute discoloration to nonyellowing systems. Eastman cellulose esters are available with a range of substituents and molecular weights that determine their solubility, compatibility, viscosity, film formation, and hardness.

For more than 80 years, Eastman has introduced innovative cellulose esters that help meet market demands—most recently Eastman Solus™ performance additives for high-solids coatings products.

Different applications demand varying properties to meet performance, aesthetic, and productivity requirements. Eastman cellulose esters offer a diverse portfolio that addresses a broad range of challenges.

Formulators have very specific application requirements that can be successfully achieved by leveraging the multifunctional performance attributes of Eastman cellulose esters. More than 50 varieties can be used singly or blended together to successfully achieve a wide array of results.
