HL-505 is an impact modifier with a core-shell structure. Its core is a moderately cross-linked acrylate rubber, which can convert external impact energy into heat. The shell is a methyl methacrylate copolymer, which is compatible with a wide range of materials. This product has good processability, high heat resistance, and can further improve the mechanical properties of engineering plastics. It is suitable for fields like PC, PC/ABS alloys, and PVC products that require high standards of weather and heat resistance.
