Eastman introduced acetate tow to the tobacco industry in 1952 and today is a leading global manufacturer, selling it as Eastman Estron™ acetate tow. Customers use Estron to produce cigarette filters and ink reservoirs for fiber-tip pens. The product line supporting this filtration material has grown through many innovations. The most significant product developed for use with cellulose acetate tow is our line of Estrobond™ plasticizers, which are used to impart rigidity and hardness to acetate fiber rods.
Eastman sells raw materials to produce acetate tow and acetate yarn through its fibers business. Cellulose acetate, fiber esters, polymers, and acetyl chemicals are used to produce this polymer.
