Finechem FN 50 (Impact Modifier)

Finechem FN 50 Acrylic Impact Modifier (AIM) is a copolymer with a core-shell structure. The core effectively transfers external impact energy into heat, and the shell is highly compatible with PVC matrix. Therefore, it exhibits excellent impact strength, weather resistance, and color durability under prolonged outdoor exposure. Acrylic impact modifiers are polymers with a typical core-shell structure. The core is a slightly cross-linked acrylate copolymer with a low glass transition temperature, while the shell is a methacrylate copolymer with good compatibility with PVC.
