Applications

Dioctyl adipate(DOA) is a typical cold resisting plasticizer for vinyl chloride polymer and its copolymer,
polystyrene,cellulosic resins and synthetic rubbers. It imparts a high plasticizing efficiency,less colour
change during light and heat attack,good softening property at low temperature.Usually applied in
cold-resisting agricultural film,artificial leather,wrapping layer for electric wires,and water tubes for outdoor use.
