Use: It is a typical cold resistant plasticizer. 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 products have good texture. It's usuallyused with di-2-ethyl hexyl phthalate and so on, in the cold resistant films for agriculture, cable clads, artificial leather, outdoor water pipes and packaging films for frozen food, etc. It also can be used as plasticizers of various synthetic rubber at low temperature andcold resistant plasticizersof the resins such as polystyrene, vinyl chloride copolymer and so on. 

Packaging: NW: 180kg. Packed in metal pail or on the clients' requirements.
