Use: It is a typical good low temperature resistance plasticizor. It has high plasticization efficiency and it won't change color easily when heated. It can endow the product with low temperature plasticity, light fastness and water resistance. DOS has less volatility than DOA. In the process, it has good lubricity and the product made from it feels good. It's often used with di-2- ethyl hexyl phthalate and so on, in the films for agriculture to resist cold, cable clads, artificial leather, outdoor water pipes and packaging films for frozen food, etc. It also can be used as plasticizors of various synthetic rubber at low temperature and low temperature resistance plasticizors of the resins such as polystyrene, vinyl chloride copolymer and so on.
