- Product Description
Fur Processing Solid Sodium Formate: Premium Grade for Superior Leather & Pelt Treatment
SHANXI ZHAOYI CHEMICAL CO., LTD brings you Fur Processing Solid Sodium Formate engineered specifically for high-end leather tanning operations. With a purity level of ≥98% and iron content controlled below 50ppm, our specialized formula prevents surface case hardening and chemical staining on delicate pelts. Manufactured at our 27,000 m² facility with an annual capacity of 150,000 tons, we deliver consistent quality backed by ISO, KOSHER, and HALAL certifications. Our strict control of chloride (≤0.03%) and heavy metals (≤0.001%) ensures your premium mink, fox, and specialty furs maintain their natural softness and color integrity throughout the chrome tanning process.
Key Features & Benefits
Superior Masking Performance
Our product acts as an effective chrome tanning buffer, preventing rapid surface reactions. You get deeper penetration into thick hides and dense fur skins, eliminating the costly problem of case hardening.
Ultra-Low Iron Content
With iron levels strictly controlled below 0.005%, you can process white and light-colored furs without worrying about unsightly blue or black staining. Your finished pelts retain their natural beauty and command premium prices.
Exceptional pH Stability
The buffering capacity within the 3.5–4.5 pH range protects delicate keratin fibers from acid shock. Your pelts stay pliable and receptive to dyeing, reducing waste from grain coarseness or chemical burns.
High Purity Formulation
At 98% content minimum with water-insoluble matter below 0.04%, you benefit from consistent dosing and predictable results. No unwanted filler materials compromise your tanning chemistry or create spotting on leather surfaces.
Free-Flowing Crystals
Our anti-caking technology ensures moisture content stays below 1.0%. You can rely on smooth handling and accurate automated dosing systems without interruptions from clumped material.

How It Works?
Masking Chrome Reactivity
When you add our sodium formate during basification, the formate ion enters the chrome complex structure. It displaces sulfate ions, reducing the astringency of chromium salts and slowing their reaction rate with collagen fibers.
Preventing Acid Shock
During pickling operations, the compound maintains constant pH levels. Your pelts avoid hydrolytic damage to hair follicles that occurs when pH swings are too rapid or extreme.
Enabling Deep Penetration
By stabilizing collagen chemistry, tanning agents penetrate deep into the hide matrix before cross-linking begins. You achieve uniform chrome distribution from grain surface to flesh side, ensuring consistent softness and strength.
Neutralizing Residual Acids
In re-tanning stages, it strips excess strong acids remaining from previous processes. Your leather structure becomes chemically neutral, ready for optimal fat-liquoring and finishing treatments.

Applications
Chrome Tanning Masking
You can add this product alone or with sodium bicarbonate during basification. It's essential when processing thick hides or dense fur skins like mink and fox where uniform chrome distribution is challenging.
Pickling Bath Stabilization
For acid-sensitive furs, it safeguards against swelling and fiber damage. You maintain optimal pickling conditions without risking the structural integrity of valuable pelts.
Premium Pelt Processing
When working with high-value white or light-colored furs, our low-iron formula prevents discoloration. Your finished products meet the strict aesthetic standards of luxury fashion markets.
Re-tanning Operations
You achieve chemically neutral leather structures ideal for automotive upholstery, wash-leathers, and specialty applications. The material ensures proper receptivity to subsequent finishing chemicals.
Industrial Leather Production
Beyond fur processing, you can apply it in general leather tanning where pH control and chrome masking improve product consistency and reduce batch-to-batch variation.
