Introduction:
DOS is a cold-resistant and environmentally-friendly plasticizer, which is added to products to provide them with softness at low temperatures and low volatility. It is mainly used as a plasticizer for PVC products and various synthetic rubbers.
Application:
DOS is the typical high quality cold resistance PVC plasticizer, with high plasticizing efficiency and low volatility. Besides its high performance in cold weather, it works well under high temperature. For its excellent insulativity and strong weather resistance property, it is often used for the production of cold resistance wire, cable material, artificial leather, pellicle, plank stuff, sheet material and so on. It is non-toxic. The toxicity factor is 500(The toxicity grade is T=1000), and any dosage fed to the white rat has not resulted in poisoning. It is quite suitable for foodstuff wrapper. It can also be used as low temperature plasticizer of many synthetic rubbers or cold resisting plasticizer of nitryl cellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, vinyl chloride copolymer and so on. Sometimes, it is used as lubricating oil of jet engine.
