ASAFLEX - High-performance Clear StyrenicBlockCopolymers (SBC)

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.
