ST Polystyrene Microspheres offer excellent heat resistance (decomposition point 300°C) and superior light transmittance, making them ideal for optical and high‑temperature plastic applications.

With a high refractive index of 1.59 and a density of 1.06 g/cm³, ST Polystyrene Microspheres provide outstanding compatibility with a wide range of plastics including PMMA, PET, EVA, PP, and PE.

ST Polystyrene Microspheres significantly improve scratch resistance, abrasion resistance, and anti‑blocking properties when incorporated into films, sheets, or molded parts.

ST Polystyrene Microspheres can also be used as an effective matting and texture agent, allowing formulators to adjust surface gloss and haptics without compromising mechanical performance.

Available in multiple particle sizes (3, 5, 8, 25, and 30μm), ST Polystyrene Microspheres enable precise control over surface finish and optical effects in engineering plastics and polyolefins.
