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.
An important advantage is improved water solubility and dissolving time and therefore energy consumption could be reduced dramatically.
Another valuable advantage is to produce an enhanced blending with fine particle materials like inorganic fillers. This characteristic provides a more uniform mold in compression molding type applications.
ELVANOL™ T grades are unique copolymers developed especially for use as warp sizes for polyester / cotton blends and other spun yarns.
What makes ELVANOL™ T grades so special is an increased solubility into water under alkaline conditions and this is the key to more effective “de-sizing”.
Their performance is not deteriorated even when recycled and the copolymers will be the most economical textile sizing agent to meet environmental requirements from the market.
