3. Application: Di-2-ethylhexy1 azelate has a good compatibility with polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polystyrene, polyvinyl acetate, cellulose acetate, nitrocellulose, ethyl cellulose, etc. It has many good properties, such as low viscosity, high boiling point, high plasticizing efficiency, small water extraction, low volatility and migration ability, excellent heat and light resistance, good electrical insulation, better cold resistance than that of dioctyl adipate. It can also be used alone or mixed with other plasticizers as plasticizers for synthetic rubbers, such as, nitrile rubber, styrene butadiene rubber and neoprene. In addition, it is a good cold-resistant plasticizer.

4. Package: Packing by 200L sealed galvanized iron bucket, 180kg net each.

5. Storage: Sealed preservation. Store at cool and ventilate place. Shelf life is12 months. It is still available if the retest results of the properties are qualified after expired date.

6. Transportation: Avoid rain, moist and sun-baked. Don't mix with strong oxidizer.
