**Product Description of Epoxidized Soybean Oil (ESO) Plasticizer**
Epoxidized Soybean Oil (ESO) is a type of plasticizer that is widely used in various industries. It is derived from soybean oil through an epoxidation process ---
### **Product Overview**
Epoxidized Soybean Oil (ESO for short) is an environmentally friendly, non-phthalate plasticizer made from natural soybean oil through an epoxidation modification process. Its molecular structure contains epoxy groups, endowing it with dual functions of plasticization and stabilization. It is characterized by being non-toxic, biodegradable, and having strong resistance to migration. It complies with international regulations such as REACH, RoHS, and FDA (21 CFR 175.300), and is widely used in PVC products, food packaging materials, and green polymer materials. It is an ideal alternative to traditional phthalate plasticizers. ---
### **Product Features and Advantages**
1. **Green and Environmentally Friendly**:
- Derived from renewable soybean oil, with a biodegradation rate of over 90%, meeting the EU EN 13432 compostable standard.
- Free of phthalates, heavy metals, and BPA, and certified by the FDA for food contact materials.
2. **High Efficiency and Stability**:
- Epoxy groups can capture free HCl during PVC processing, delaying material thermal aging and extending product lifespan.
- Excellent resistance to migration, remaining stable over long-term use and maintaining product surface smoothness.
3. **Versatility**:
- Combines the functions of a plasticizer, heat stabilizer, and lubricant, reducing the number of additives in the formula.
4. **Safety and Low Toxicity**:
- Acute oral toxicity (LD50) > 5000 mg/kg, suitable for sensitive applications such as children's toys and medical supplies.
5. **Low Temperature Resistance**:
- Maintains PVC flexibility at -30°C, suitable for products used in cold environments. ---
