Elvanol T-66 Polyvinyl alcohol DuPont Polyvinyl alcohol (PVOH) ADHESIVE Elvanol® T-66 is a unique copolymer supplied as a white , granular solid. Elvanol® T-66 slurries easily in cold water without lumping and dissolves readily on heating to 85°C (185°F) or higher for 20-30 minutes. Solutions of Elvanol® T-66 are noncorrosive and nontoxic. They are stable in viscosity and can be stored for long periods - for example, over weekend shutdown periods. Elvanol® T-66 is a unique copolymer grade of polyvinyl alcohol (PVA) for use on spun yarns of cotton, polyesters or blend yarns. A lower viscosity resin than Elvanol® T-25, it was developed specifically 1) to meet the demands of the new medium to high pressure slashers, in terms of better runnability and higher-solids formulations, and 2) to increase the productivity of PVA Recovery Systems based on ultrafiltration, by an improvement in desizeability and flux rates Provides advantages: On the Slasher On the Loom On the Finishing Range Polyvinyl alcohol copolymer. Gives noncorrosive, nontoxic solutions that are stable in viscosity and can be stored for long periods. Can be used on spun yarns of cotton, polyesters or blend yarns.
