Application Guide:

Using sebacic acid and butanol as raw materials, under the catalytic action of sulfuric acid, the esterification reaction is carried out at about 140 ° C. After the reaction is completed, the water layer is neutralized and separated, decolorized with activated carbon, dealcoholized and washed with hot water . Can be used for packaging materials in contact with food, cold resistance auxiliary plasticizer.

Applications:

Cables, food packaging, etc.
