Dioctyl adipate( DOA )
2022-10-31
Molecular formula: C22H42O4
Molecular weight: 370.57
DOA is a typical plasticizer in low temperature. With good plasticity and color change ability in heat condition, it can be used in PVC, PE copolymer, Ps and synthetic rubber resin. It can offer good softness and light resistance in artificial leather, board and pipe. In plasticizing paste, it has stable Viscosity and low initial Viscosity. It can be used in food packing in USA, France, Italy, Japan and Holland, etc.
