K Resin(Sunion Resin) SL-802

K Resin SL-802 is a styrene-butadiene block copolymer (SBC), commonly known as K-Resin from Sunion. Composed of approximately 75% styrene and 25% butadiene, it is a colorless, non-toxic, highly transparent impact-resistant resin. Key features include high transparency, excellent impact resistance (3–5× that of general polystyrene and SAN), good processability via injection molding, extrusion, or blow molding, and compliance with food-contact safety standards. Applications include food packaging, medical devices, toys, stationery, and plastic modification.
