Mowiol

Description

[Kuraray KAI] A former trademark for a polyvinyl alcohol emulsion. Mowiol® resins produce strong films are resistant to grease and oils. Mowiol® resins are used for paper coatings, textile sizes, printing inks, cosmetics, eye drops, and water soluble packages.

Currently, Kuraray sells multiple products containing PVAs.

• POVAL™ is the brand name of Kuraray’s globally produced polyvinyl alcohol (PVOH). KURARAY POVAL™ features an extremely wide-ranging field of applications. The main uses are in the paper, adhesive, textile and construction industries, as well as in ceramics, packaging and electronics. The physical and chemical properties make PVOH very versatile. It features water-solubility, excellent film forming characteristics, high tensile strength and elasticity, as well as resistance against organic solvents and dispersing power.
• ELVANOL™ is a recent addition to Kuraray’s polyvinyl alcohol product portfolio. Its unique particle morphology, coming from a special production process expands its range of applications. ELVANOL™ can be dissolved in the continuous cooking process designed for starch in which standard polyvinyl alcohols remain undissolved. This will be a significant benefit in paper coating applications, especially where polyvinyl alcohols are used together with starch to enhance performance.
• EXCEVAL™ is the trade mark of Kuraray’s hydrophobically modified polyvinyl alcohol especially designed for the requirements of “high water resistance”. When used as a dispersing aid / protective colloid for the manufacture of polyvinyl acetate emulsion for wood adhesives
