The PSN is a high toughness impact modifier specifically developed for polystyrene (PS), designed to address the inherent limitations of PS materials, such as high rigidity, brittleness, and insufficient impact resistance.
With excellent compatibility with the PS matrix, PSN effectively enhances toughness, elasticity, impact resistance, and crack resistance, while maintaining good processing flowability, dimensional stability, and surface quality. This enables the final products to achieve both structural strength and long-term reliability.
As the use of recycled PS becomes increasingly widespread, material embrittlement and performance degradation have become critical challenges in mass production. PSN effectively improves the mechanical properties of recycled PS, helping customers enhance product quality, extend service life, and achieve both cost efficiency and sustainability goals.
