NANOSTRENGTH® E21/E20

NANOSTRENGTH® E21/E20 by Arkema is acrylic block copolymer-based impact modifier. It has low-medium molecular weight, low polarity, and medium phase content. It is a new family of self-assembling block copolymer SBM, constituting of polystyrene, 1, 4-polybutadiene and syndiotactic poly (methyl methacrylate). It disperse easily and impose a structuration to the host matrix. This organization imparts unique combinations of properties, such as impact strength, high rigidity and transparency. It has applications as additive in engineering polymer and new class of transparent acrylic materials.
