ACR (Acrylic copolymer) is an acrylate copolymer with a core-shell structure, and is a
PVC Impact Modifier with excellent comprehensive properties. Usually people call the additives used for the purpose of improving the toughness of plastics as impact modifiers, and the additives used for the purpose of improving processing properties are called processing modifiers. ACR is a plastic additive with dual functions of impact resistance modification and processing modification. Due to its core/shell structure, its PVC products have excellent impact resistance, low temperature toughness, compatibility with PVC, weather resistance, Stability, processability, and moderate performance and price ratio, can significantly improve the fluidity and thermal deformation of PVC melt, promote plasticization, and make the product surface smooth and beautiful. It is mainly used in rigid and semi-rigid PVC products, especially chemical building materials, such as profiles, pipes and fittings, plates, foam materials, etc., and is especially suitable for outdoor products. It is a type of
Impact Modifier that is used in large quantities today and will be developed in the future. PVC is one of the plastic varieties with the largest production and consumption. It has many valuable properties, but it also has many shortcomings. Poor toughness is one of its major shortcomings. In order to improve its toughness without damaging its tensile strength and other physical properties, PVC impact modifier came into being.
