Acrylic Impact Modifier

About Acrylic Impact Modifier

Acrylic impact modifier or namedACR impact modifier contains the core formed by acrylate crosslinked elastomer, and the shell composed of methyl methacrylate ethyl acrylate copolymer is outside the core. The impact strength of a good blend system of ACR and PVC can be more than 10 times higher than that of PVC, and its tensile property is also greatly improved, especially for outdoor rigid PVC plastic products. Compared with other impact modifiers, ACR has better processability, impact resistance, beautiful surface and excellent aging resistance.Our impact modifiers equivalent to the Dow Paraloid KM series,Kane Ace FM series,LG IM series,Mitsubishi Metablen W series,Arkema DURASTRENGTHD series,AKDENZ DMA,Shandong Rike HL series.The size of ACR particles is one of the key factors that affect the impact modification effect. The particle size of good ACR rubber core should be about 0.1-o.5, too large and too small is not good. In particular, it should be noted that under the same processing conditions, the impact strength of PVC / ACR blends prepared by different stable systems is quite different. If barium stearate cadmium stearate is used as stabilizer under the same conditions, it has higher impact resistance than lead salt stabilizer.Acrylic impact modifieris a copolymer of methyl methacrylate, acrylate and other monomers. ACR is the best impact modifier developed in recent years. It can increase the impact strength of the material by dozens of times. It is a shell composed of methyl methacrylate and ethyl acrylate polymer. The chain segments with butyl acrylate crosslinked rubber elastomer as the core are distributed in the inner layer of particles. It is especially suitable for the impact modification of PVC plastic products for outdoor use. Compared with other modifiers, ACR used as impact modifier in PVC plastic door and window profiles has the characteristics of good processing performance, smooth surface, good aging resistance and high fillet strengthLS51 equivalent to Dow KM-1,Kaneka FM-22,Arkema D-200,LG IM-808,Baerlocher E-ST 2D.LS50 equivalent to Dow KM-342,,Kaneka FM-50,Arkema D-529,LG IM-812,Baerlocher E-ST 4.LS55 equivalent to Dow KM-369 or KM390,,Kaneka FM-55,Arkema D-520.LS-61 equivalent to Dow KM-355P,,Kaneka FM-40,Arkema D-320,LG IM-809,Baerlocher E-ST 3For TDS and MSDS, you can contact our Sales and Marketing Department or you can reach us through thecontact page.
