1.DOS is an excellent cold-resistant plasticizer, with high plasticizing efficiency, high stability and low volatility. Except good cold-resistance, it also has good heat-resistance, light-resistance, electric and insulation, suitable for PVC, EVC, polystyrene and synthetic rubber resins.
2. Especially suitable for the production of cold-resistant wire, cable material, luxury food, meat plastic wrap, artificial leather, thin film, conveyer belt, board, sheet, etc. Usually be used with PA esters.
3. As the low-temperature plasticizer for synthetic rubbers, DOS has no effect on the vulcanization of rubber.
