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.
Package and storage
Packed in 200 liter galvanized iron drum,net weight 180 kg/drum.Stored at dry,shady,ventilated place.
Prevented from collision and sunrays,rain-attack during handling and shipping.
1.Dioctyl adipate /DOA is a typical cold resisting plasticizer
2.DOA plasticizer mainly used on PVC,PS,cellulosic resins and synthetic rubbers
3.Dioctyl adipate usually used with dop plasticzer together
