LG Processing Aid 912 absorbs and disperses impact energy from external impact. LG Processing Aid 912 Shell plays a role in enhancing compatibility with base polymer (pvc). Also, the type of rubber that is the core (Butyl acrylate, butadiene) determines the industry. That is, the core (Rubber) is the key to improving the impact strength. LG Processing Aid 912 Since the components of these cores have low compatibility with PVC and various base polymers, To promote this, a highly compatible material is applied to the shell.
