High-performance Clear Styrenic Block Copolymers (SBC) Asaflex™
Asaflex™ is a styrene-butadiene block copolymer (SBC) characterized by both superior transparency and high impact resistance. As the polybutadiene-phase (i.e., the rubber-phase) dispersion in Asaflex™ is on a finer scale than the wavelength of visible light, Asaflex™ has flexibility and hinge characteristics while maintaining high transparency.
Due to good compatibility with styrenic resins such as GPPS, Asaflex™ can be blended at arbitrary ratio.
