Dioctyl phthalate

　　Main Application Areas

　　The core function of DOP is as a plasticizer, which is achieved by embedding between polymer molecular chains to weaken intermolecular forces, making hard and brittle polymers (such as PVC) soft and easy to process. Its applications are concentrated in:

　　Polyvinyl Chloride (PVC) Products (accounting for over 80% of usage):

　　Soft PVC: Films (agricultural films, packaging films), artificial leather, pipes (infusion tubes, drainage pipes), wire and cable insulation layers, toys, gloves, etc., imparting flexibility to materials (such as the "soft and bouncy" texture of PVC toys).

　　Rigid PVC: Small additions can improve processing fluidity (e.g., reducing cracking during PVC sheet molding).

　　Other Polymer Materials:

　　Rubber: Used as a plasticizer to improve the elasticity and processability of nitrile rubber and neoprene rubber

　　Coatings, Adhesives: Increase coating film flexibility and lower the glass transition temperature (to avoid low-temperature cracking)
