Addressing Leather Dyeing Challenges with 99.6% Oxalic Acid (CAS 144-62-7)
Many leather manufacturers face critical issues with inconsistent dye penetration and surface blemishes caused by impure acid reagents. In our 10+ years serving leather industries across 50+ countries, we’ve seen how even 0.5% purity fluctuations can lead to uneven dye absorption and production delays. Unstable supply chains further compound these problems, forcing factories to halt production lines while waiting for reliable raw materials.
A Stable and Reliable Chemical Supply Solution
Our Oxalic Acid (CAS 144-62-7) delivers the consistent 99.6% purity that leather dyeing processes demand. With a monthly production capacity of 5000 tons and strategic shipping from Qingdao, Tianjin, and Shanghai ports, we ensure steady supply even during peak production seasons. This reliability has made us the trusted partner for over 10,000 industrial customers worldwide, including major leather manufacturers in developing countries.
Typical Industrial Applications
As a key Leather Dyeing Acid, this dicarboxylic acid plays a vital role in the leather processing industry by adjusting pH levels during dyeing and enhancing color fastness. Beyond leather applications, it functions as an effective reducing agent in mining operations and serves as a cleaning agent for stone surfaces. All uses are strictly limited to industrial manufacturing processes, adhering to international safety standards.
Why Key Specifications Matter
The 99.6% purity level of our Oxalic Acid minimizes impurities that could interfere with dye-reagent reactions, ensuring uniform color distribution across leather products. Its defined melting point (101-102ºC) provides consistent thermal stability during processing, while the medium strong acidity offers precise pH control without damaging collagen fibers. The white powder form ensures easy and accurate dosing, reducing material waste and ensuring batch-to-batch consistency critical for large-scale production.
What You Gain With Our ISO9001 Oxalic Acid
Choosing our ISO9001-certified Oxalic Acid means investing in production efficiency and product quality. Compared to lower-grade alternatives, our high-purity acid reduces reject rates by minimizing dyeing defects, ultimately lowering production costs. The inclusion of SGS-certified quality documentation ensures compliance with international trade standards, simplifying customs clearance processes. Our commitment to consistent supply eliminates the hidden costs of production downtime caused by material shortages.
