PARALOID™ EXL-2388 Impact Modifier

Paraloid™ EXL 2388 by Dow Chemical is a general purpose all acrylic core-shell impact modifier. Provides an excellent balance of impact resistance and modulus retention in a variety of engineering resins. Because of the core-shell structure and acrylic composition, the improvement in impact performance is obtained with only minor effect on other mechanical properties, such as heat distortion temperature, and with no adverse effect on weatherability. Improved impact properties can be expected in the following engineering resins; polycarbonate (PC), polyesters (PET, PBT), blends of these thermoplastics and glass fiber reinforced systems. Has a cross-linked poly (butyl acrylate) core with a grafted poly-methyl methacrylate shell. This core-shell structure allows the product to disperse as discrete particles in the matrix. It will not dissolve in solvents or melt. Paraloid™ EXL 2388 by Dow Chemical finds utility in a variety of conversion processes typically encountered for engineering resins, including extrusion, injection molding, blow molding and thermoforming.
