Adaptation of New Acrylic Impact Modifier Technology to PVC Extrusion Industry Trends

摘要

The new generation of acrylic impact modifiers is designed to address the relationship between polymer structure,processing and physical properties of extruded vinyl materials.Better impact resistance can be achieved with optimal design of core shell acrylic modifier.High through-put processing with acceptable melt rheology such as melt pressure,temperature and motor load can also be achieved through polymer design and modifications.A broad processing window with lower levels of acrylic impact modifiers will become the future trend in PVC impact modification.
