Zhejiang Asia Chemstation
— Your Strategic Partner for Leather Industry Solvents & Process Media
Zhejiang Asia Chemstation is a dedicated supplier of high-quality solvents and process media for the leather processing and synthetic leather manufacturing industry. Our product portfolio covers degreasing processes, finishing systems, polyurethane synthetic leather production, and environmentally friendly alternatives. With deep understanding of the leather industry's requirements for solvency, evaporation rate, safety compliance, and environmental sustainability, we are committed to providing precise, stable, and efficient solvent solutions.
Core Solvent Systems & Applications
| Process Stage | Solvent/Medium Category | Common Types | Key Properties & Functions |
|---|---|---|---|
| Degreasing | Hydrocarbon Solvents | Kerosene | Removes natural fats from raw hides; cost-effective |
| Chlorinated Solvents | Trichloroethylene, Perchloroethylene (Tetrachloroethylene) | Efficient degreasing, moderate evaporation; suitable for organic solvent degreasing | |
| Ether-Based Eco-Solvents | Dipropylene Glycol Butyl Ether (DPNB) | Low odor, strong environmental profile; ideal for modern clean production | |
| Finishing & Synthetic Leather Production | Aromatic Hydrocarbons | Toluene, Xylene | Excellent solubility; commonly used as thinners and solvents |
| Fast-Drying Ketones | Methyl Ethyl Ketone (MEK, Butanone) | Fast evaporation rate; suitable for coating processes and fast-dry systems | |
| Strong Polar Solvents | Dimethylformamide (DMF) | Core reaction medium and solvent for wet-process PU synthetic leather production | |
| Ester Solvents | Ethyl Acetate | Used in color paste preparation and resin dissolution; mild odor, operator-friendly | |
| Auxiliary Media & Eco-Friendly Systems | Environmentally Friendly Media | Water | Used in waterborne finishing systems and some cleaning processes; green and sustainable |
| Surfactants (Synergistic Agents) | Fatty Alcohol Polyoxyethylene Ether (AEO) | Not a traditional solvent, but plays a key synergistic role in emulsification, penetration, and degreasing |
Quick Reference: Solvent Selection by Leather/Synthetic Leather Process
| Leather/Synthetic Leather Process | Recommended Solvent/Medium | Primary Function |
|---|---|---|
| Raw Hide Degreasing (Conventional) | Kerosene, Trichloroethylene, Perchloroethylene | Fat removal |
| Raw Hide Degreasing (Clean Production) | Dipropylene Glycol Butyl Ether (DPNB) | Low-odor, eco-friendly degreasing |
| Wet-Process PU Synthetic Leather Production | Dimethylformamide (DMF) | Reaction medium & solvent |
| Coating & Fast-Dry Processes | Methyl Ethyl Ketone (MEK) | Rapid evaporation and film formation |
| Color Paste Preparation & Resin Dissolution | Ethyl Acetate | Dissolution and thinning |
| General Thinning & Dissolution | Toluene, Xylene | Universal thinners |
| Waterborne Eco-Friendly Systems | Water, AEO Surfactants | Medium & penetration/emulsification |
