How to better understand the difference between plastic plasticizer and toughener?

        Plasticizer: According to the plasticizer item 19, the usual plasticizer refers to the plasticizer mainly DOP and DBP. The main role is to increase the compatibility and plasticizing efficiency of the product.

        Toughener: Usually a single or multiple polymer composition in the product. Any substance that reduces brittleness and increases toughness without affecting other major properties of the adhesive is called a toughening agent. Some plasticizers can also increase their toughness, but the rigidity, strength, and heat distortion temperature are greatly reduced. Can not meet the structural bonding requirements, the real toughening agent is to simultaneously improve the toughness of the product, while at the same time does not affect the chemical stability and physical properties of the product and good mechanical properties.
