Addressing Leather & Textile Dyeing Challenges with Anhydrous Oxalic Acid 99.6% CAS 144-62-7
We’ve witnessed countless production disruptions in leather and textile dyeing facilities—batch-to-batch purity variations causing uneven color absorption, delayed shipments due to unstable supply chains, and substandard raw materials leading to costly rework. As a team with over a decade in chemical manufacturing, these are not just statistics but daily realities we’ve helped factories overcome.
A Stable and Reliable Chemical Supply Solution
Our Anhydrous Oxalic Acid 99.6% CAS 144-62-7 delivers the consistency critical for industrial dyeing processes. With a production capacity of 6000 tons monthly and ISO9001-certified manufacturing, we ensure uninterrupted supply even for large-scale textile plants and leather tanneries across 50+ countries.
Typical Industrial Applications
This Industrial Grade Oxalic Acid Powder serves as a vital auxiliary in leather processing, facilitating degreasing and pH adjustment for uniform dye penetration. In textile manufacturing, it functions as a reducing agent, enhancing dye fixation on natural fibers while maintaining fabric integrity. Its applications extend to mining operations and stone cleaning, demonstrating versatile industrial utility.
Why Key Specifications Matter
The 99.6% purity level minimizes impurities that could interfere with dye-reagent reactions, ensuring consistent colorfastness in leather products. Its controlled solubility profile—readily dissolving in water and ethanol—allows precise concentration adjustments during dye bath preparation. The medium strong acidity provides optimal pH control without damaging delicate textile fibers, while the stable melting point ensures predictable behavior in high-temperature dyeing processes. These specifications collectively reduce production variables, directly impacting product quality and manufacturing efficiency.
What You Gain With Our Product
Choosing our Ethanedioic Acid 99.6% CAS 144-62-7 translates to measurable operational benefits: reduced batch rejection rates due to consistent quality, lower material waste from precise dosing, and minimized production downtime from reliable supply. Unlike inferior products that risk equipment corrosion or product contamination, our SGS-tested oxalic acid meets strict international export standards, eliminating customs clearance delays. The 25kg packaging format optimizes storage efficiency while reducing handling labor costs for industrial facilities.
