About ELVANOL™
ELVANOL™, is known for its unique particle morphology derived from a special production process, expanding its application range. It can dissolve in continuous cooking processes designed for starch, where standard polyvinyl alcohols might remain undissolved, which is particularly beneficial in paper coating applications. It also offers improved water solubility and dissolving time, potentially reducing energy consumption significantly.
Industries Used
ELVANOL™ can produce enhanced blending with fine particle materials like inorganic fillers, providing a more uniform mould in compression moulding-type applications. ELVANOL™ T grades, developed especially for warp sizes for polyester/cotton blends and other spun yarns, offer increased solubility in water under alkaline conditions, vital to more effective “de-sizing.”
Enhances paper by providing a strong coating that resists water and improves quality.
Ensures a smooth mould by blending well with fine particle materials.
Its T grades provide easy “de-sizing” and meet environmental standards.
