1. Product Description
Dibutyl Fumarate is a high-purity diester of fumarate; in addition, it is characterized by its colorless liquid appearance. Furthermore, it features the following properties:
- Boiling Point: 141°C
- Density: 0.987 g/cm³
- Flash Point: 136.4 ± 18.2°C
- Solubility: Insoluble in water; soluble in acetone and chloroform
- Refractive Index: 1.452
Manufactured primarily in China by leading manufacturers in specialized factories, Dibutyl Fumarate is produced using fumaric acid and butanol in the presence of a catalyst. Consequently, this compound contains unsaturated double bonds, which enable copolymerization with various monomers. As a result, this enhances plasticity, making it an ideal internal plasticizer for PVC and other polymers. Moreover, many suppliers in China rely on high-quality production from these reputable factories to meet industry standards.
