Dibutyl Sebacate (DBS), with CAS No 109-43-3, also known as Sebacic acid dibutyl ester and Sebacic acid di-n-butyl ester or Di-n-butyl sebacate, is a sebacic acid ester plasticizer, and it is a colorless or light-yellow transparent liquid. Manufacturers and suppliers in China use dibutyl sebacate in food contact packaging materials and cold-resistant auxiliary plasticizer. The factory produces it by the esterification reaction of sebacic acid and octanol.

4. Application & Advantages
Firstly, people use DBS for food contact packaging materials, cold resistance auxiliary plasticizer. Since this product is compatible with most resins and synthetic rubbers, so manufacturers can use it as the main plasticizer. Dibutyl Sebacate plasticizer also has excellent low temperature performance and oil resistance. However, it has high volatility. Therefore, factories mostly use it with phthalate plasticizers with good durability.
5. Packaging / Storage / Transport
Iron drum packing, net weight 180 kg/drum. Store in a dry and ventilated place indoors and prevent violent impact and rain during transportation. In addition, it is risk of burning in high heat, open flame or contact with oxidants.
