WebJan 3, 1998 · Basically two main groups of cellulose-materials can be distinguished: regenerated celluloses are suitable only for fibre and film production from conventional … WebCellulose acetate is a thermoplastic that responds well to gas plasma treatment. Its inherently low surface energy and poor polarizability means the surface cannot provide enough energy to bond with adherents such as adhesives and inks. Gas plasma surface treatment solves this problem by increasing cellulose acetate surface energies.
WebFeb 1, 2013 · When the molar substitution of PLA (MS PLA) was above 1.71, the CA- g -PLA copolymers exhibited thermoplastic behavior and could be processed by conventional thermal processing methods, such as injection molding and melt spinning. Cellulose is the most abundant, renewable, biodegradable natural polymer with many attractive properties. For the subsequent production of very high-quality, thermally stable, brightly colored and color-stable thermoplastic molding compounds, the cellulose acetate flakes are also bleached and stabilized in additional process steps (to minimize thermal degradation and discoloration) before final drying.
