DOA is the typical high quality cold resistance PVC plasticizer, with high plasticizing efficiency and low color distortion upon heat, which endow the products with excellent pliability and light stability under low temperature. It is water-resisting as well. It reveals favourable lubricating action when processed and is often added with phthalate to make cold resistance agricultural film, cable clad, artificial leather, outdoor water tube, packaging film for frozen food and so on.

It is non-flammable and has stable property in normal temperature. Its water solution is slightly alkaline , and can react with hydrochloric acid, sulfuric acid, nitric acid, acetic acid and oxalic acid etc. to form melamine. In neutral or slightly alkaline state, it can be synthesized with formaldehyde to form various methylol melamines, but in subacidity (pH value 5.5-6.5), it can have polycondensation with the methylol derivatives to generate resin products. In case of strong acid or strong alkaline water solution, it can be hydrolyzed, the amino group is generally replaced by hydroxyl group to first ammeline first, and then it is further hydrolyzed to generate ammelide, and finally generate cyanuric acid.

Hot melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly supplied in solid cylindrical sticks of various diameters, designed to be melted in an electric hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure.
