BIOSTAB HPS is an advanced Hydrogen Peroxide Stabilizer specifically developed for use in alkaline bleaching processes. It is designed to control the decomposition rate of hydrogen peroxide, ensuring a uniform release of oxygen throughout the bleaching cycle. By regulating this reaction, it prevents localized over-oxidation and fiber damage, resulting in a consistent, high-degree whiteness while maintaining the structural integrity and tensile strength of the textile material.
Key Benefits:
Controlled Oxygen Release: Provides a steady and regulated decomposition of peroxide, maximizing bleaching efficiency and reducing chemical waste.
Fiber Protection: Minimizes the risk of catalytic damage and "pinholes" by suppressing the aggressive, rapid breakdown of bleaching agents.
Improved Whiteness: Ensures an even and high level of brightness across the entire fabric surface, eliminating blotchiness or yellowing.
Silicate-Free Formulation: Helps prevent the formation of harsh silicate scales on machinery and fabric, leading to a softer hand-feel and easier equipment maintenance.
Application Guidelines:
Usage: Optimized for exhaust and continuous bleaching of cotton, linen, and their blends in both cold and hot peroxide bleaching systems.
Dosing: Apply at 0.2 to 0.5 g/l, depending on the concentration of hydrogen peroxide used, the temperature of the bath, and the desired degree of whiteness.
Compatibility: Works efficiently in the presence of sequestrants and wetting agents, enhancing the overall quality of the pre-treatment bath.
