Acrylic Impact Modifier

About Acrylic Impact Modifier

Acrylic Impact Modifier (ACR): Consists of a core formed by crosslinked acrylate elastomer and a shell composed of methyl methacrylate ethyl acrylate copolymer. A well-blended system of ACR with PVC can increase impact strength over 10 times compared to unmodified PVC and significantly improve tensile properties, especially for outdoor rigid PVC products.

Compared to other impact modifiers, ACR provides:

• Better processability
• Higher impact resistance
• Beautiful surface finish
• Excellent aging resistance

Our ACR impact modifiers are equivalent to the following international series:

• Dow Paraloid KM series
• Kane Ace FM series
• LG IM series
• Mitsubishi Metablen W series
• Arkema DURASTRENGTH D series
• AKDENZ DMA
• Shandong Rike HL series

Particle Size: One of the key factors affecting performance. Optimal rubber core particle size is 0.1-0.5 um. Too large or too small reduces efficiency. Impact strength also depends on the stability of the system; for example, barium or cadmium stearate stabilizers yield higher impact resistance than lead salts under the same conditions.

ACR is a copolymer of methyl methacrylate, acrylate, and other monomers. Its structure features a butyl acrylate crosslinked elastomer core surrounded by a shell of methyl methacrylate-ethyl acrylate polymer. Especially suitable for outdoor PVC products, ACR improves impact strength, processing performance, surface finish, aging resistance, and fillet strength.
