Product Portfolio - Caiber S.A

1 Product Portfolio constructiona broad range of productsWelcome to Dow Wolff Cellulosics !Dow Wolff Cellulosics was created as a new business unit, encompassing the activities of what were previously Wolff Walsrode AG and The Dow Chemical Company s Water Soluble Polymers business. Joining these two entities together into Dow Wolff Cellulosics allows us to capitalize on the strengths of both organizations and deliver a reinforced Portfolio of products and services to the worldwide end-use markets on cellulosics and other key chemistries for enhanced performance. Dow Wolff Cellulosics is a preferred development supplier and application development specialist in the cellulosics industry, catering to the changing needs of formulators and brand owners whose label claims are enabled by Dow combined business Portfolio is based on strong manufacturing capabilities that are among the most advanced in our sector, innovative research and development, and knowledgeable, highly qualified a market leader in cellulose ether polymers, Dow Wolff Cellulosics offers a broad spectrum of products and solutions for construction applications, which include both cellulose ethers and redispersible latex powders.
