Type: Pearlstick™ 5778 TPU is a Polyester-Type Thermoplastic Polyurethane (TPU).
Features: It is especially well suited for dispersing co-ferrite as well as Cr02 pigments used in video, audio, and data storage applications. This product offers excellent hydrolytic stability under accelerated test conditions as well as outstanding pigment dispersion characteristics. Because of its medium Tg, it offers excellent adhesion and easier calendaring for high quality video and audio formulations. An excellent video tape can be formulated by blending with other harder dispersing resins. It is also used for dispersing high-surface–area pigments as a polymeric dispersant.
Uses: Tape binder, inks, lacquers and polymeric dispersing polymer for pigment dispersion
