Impact Modifiers
Impact modifiers are added to compounded materials to improve durability and toughness of plastic resins. In addition to the impact performance, a number of other characteristics of the material such as optical and tensile properties, weatherability, processability, flammability, heat distortion and cost can also be improved by adding impact modifiers. One of the major applications of impact modifiers are PVC resins:MBS (Methyl Butadiene Styrene) and Acrylics impact modifiers enhance the impact resistance of the PVC products without impairing other properties.
