Mazzucchelli has signed a joint venture agreement with Eastman Chemical Company in China for the production of a cellulose acetate compound, a biopolymer used in various injection printing applications including eyewear frames. Mazzucchelli says it is convinced that the partnership will benefit from combining the quality of the cellulose acetate produced by Eastman with its own know-how in the processing of acetate sheets for the eyewear industry. Eastman claims that demand for cellulose acetate is bound to rise, thanks not only to new applications in liquid crystal displays and others, but also in more traditional areas such as fashion eyewear, where design flexibility, physical properties and the development of materials from sustainable sources are all important factors.
