Name: LG Chem Impact Modifier MB872 Toughener
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of LG Chem Impact Modifier MB872 Toughener

High-efficiency impact enhancement for rigid PVC and engineering thermoplastics without compromising stiffness or heat resistance.
Excellent dispersion stability in melt processing, ensuring uniform toughening performance across extrusion and injection molding operations.
Low-temperature impact resilience with outstanding notched Izod strength retention down to –10 °C.
Compatible with common stabilizer systems (e.g., Ca/Zn and organotin), minimizing formulation interference.
Non-migrating acrylic core-shell structure ensures long-term weatherability and surface integrity in outdoor applications.
