Waxes
High-purified ester waxes for toner release performance.
Enable smooth fusing, stable charge, and consistent image quality in electrophotographic printing.
High-Purity Ester Waxes for Toner Release and Print Stability
Waxes (high-purified solid esters) are functional additives used in electrophotographic toner to improve release properties during the fusing process. By reducing adhesion between toner particles and fuser rollers, ester waxes ensure smooth release, minimize offsetting, and enhance durability of printed images.
Their controlled melting points, low impurity levels, and excellent compatibility with common toner resins make them a reliable choice for both black and color toner formulations. In addition, ester waxes contribute to charge control and environmental stability, supporting high-resolution printing with consistent performance.
NAGASE supplies high-purified ester waxes worldwide with technical support and customized grades to meet toner industry requirements.
Applications
