Overcoming Leather Processing Challenges with Oxalic Acid 99.6% (CAS 6153-56-6)
We’ve witnessed leather manufacturers struggle with inconsistent acid concentrations causing uneven deliming results, while科研 teams face reproducibility issues due to batch-to-batch purity variations. Delays from unreliable suppliers have halted production lines, and hidden impurities in lower-grade oxalic acid have compromised final product quality. These are the exact challenges we’ve solved for over a decade in chemical supply.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid 99.6% delivers the consistent purity and performance needed to address these critical pain points. With a production capacity of 6000 tons monthly and strategic loading ports in Qingdao, Tianjin, and Shanghai, we ensure uninterrupted supply for both large-scale leather processing facilities and precise laboratory applications across 50+ countries.
Typical Industrial Applications
As a key Leather Processing Acid, this Ethanedioic Acid Powder excels in deliming and pickling processes, effectively removing lime from hides while controlling pH levels for optimal tanning results. Beyond leather treatment, its strong reducing properties make it valuable in mining operations for mineral processing and in stone cleaning applications where controlled acidification is required.
Why Key Specifications Matter
The 99.6% minimum purity ensures minimal impurities that could interfere with leather processing reactions, reducing the risk of surface blemishes or uneven texture development. Its defined melting point (101-102ºC) guarantees consistent dissolution behavior in aqueous solutions, critical for maintaining precise acid concentrations during deliming. The medium strong acidity provides the ideal balance between reactivity and control, preventing over-processing of delicate hides. As a saturated dicarboxylic acid, it offers stable chelating properties essential for removing metal ions that could compromise leather quality.
What You Gain With Our Product
Choosing our Industrial Oxalic Acid means eliminating the hidden costs of substandard materials – fewer production rejects, reduced rework, and consistent end-product quality. Our ISO9001-certified manufacturing process ensures compliance with international industrial standards, while SGS verification provides third-party assurance of our quality claims.
