Material Notes:
Elvanol® polyvinyl alcohol (PVOH) is used in the manufacture of spiral wound tubes, coated paper and linerboard, and specialty water-soluble films. Its higher binding capacity versus synthetic latex and starch make it attractive for use in coatings. It adds strength in recycle board and adds barrier properties for improved oil and grease resistance.Applications: Silicone releaseOil and grease resistanceLabel stock pigment coatingFluorochemical extenderStrengthening recycle boardWater Soluble Films Pouches and sachets manufactured with films of DuPont™ Elvanol® are water soluble, dissolving as they release their content into cold or warm aqueous solutions. Applications include water treatment chemicals, dyes, laundry detergents, agricultural chemicals, disinfectants, industrial cleaning chemicals and other areas benefiting from ready-to-use, pre-measured dosages or reduced packaging waste.Information provided by DuPont.
