1. Product Description
Dibutyl Fumarate is a diester of fumarate, a colorless liquid in appearance. In short, Boiling point 141℃, Density 0.987g/cm³, Flash point 136.4±18.2 ℃, Solubility insoluble in water, soluble in acetone, chloroform, Refractive index 1.452. Most of Manufacturers or suppliers in China use fumaric acid and butanol in the presence of a catalyst to produce it. With unsaturated double bonds, hence it can copolymerize with a variety of monomers and the resulting copolymer can enhance plasticity. So factories use it as an internal plasticizer in PVC and other polymers.

4. Application & Advantages
Dibutyl Fumarate is an internal plasticizer. In addition, it can copolymerize with a variety of monomers and the resulting copolymer can enhance plasticity. It is used as a comonomer in the production of various polymers such as polystyrene, and the resulting copolymers are often used in the preparation of coatings, adhesives, and surface conditioners.
5. Packaging / Storage / Transport of dibutyl fumarate
Iron drum packing, net weight 200 kg /drum. Firstly, store in a cool, ventilated warehouse. Secondly keep away from fire and heat. In addition, maintain the container sealed. In addition, waterproof and sun-proof, and store separately from alkalis, oxidants, etc. When handling, light loading and unloading should be done to prevent damage to packaging and containers.
