Product Usage

Dioctyl adipate is a typical cold resistant plasticizer. This product has high plasticizing efficiency, high thermal plasticizing efficiency, and low thermal discoloration. It is suitable for various resins such as polyvinyl chloride, vinyl chloride copolymers, polystyrene, and synthetic rubber. It can endow the product with good low tenderness, softness, and light resistance, and the product has good hand sensitivity. It is commonly used with main plasticizers such as DOP and DBP in cold resistant agricultural films, frozen food packaging films, wire and cable coatings, artificial leather, boards, outdoor water pipes, etc. When used for plasticized paste, the initial viscosity of the paste is low and the viscosity stability is good.

packing of products

200L closed galvanized iron drum packaging, with a net weight of 180Kg per drum.

Storage method

Store in a cool and ventilated place in a sealed manner. The shelf life is 12 months, and it can still be used after passing the retest.

Product transportation

During transportation, prevent exposure to sunlight and stay away from strong oxidants.
