Research on the application of high gloss scratch resistant
and spray free ABS injection molding packaging

Abstract: This article reports the preparation of various formulations of high gloss scratch resistant spray
free acrylonitrile butadiene styrene (ABS) materials using blending granulation technology. The formulations
include metal aluminum powder (containing additives), silicone powder, and polymethyl methacrylate
(PMMA). The surface properties of the material were further optimized using a high gloss seamless injection
molding process, and the glossiness, brightness, pencil hardness, and friction coefficient of the material
were systematically analyzed. The research results show that adding large particle size (50 μm or more)
metal aluminum powder (including additives) can effectively improve the surface high gloss effect of ABS.
Combined with the high gloss seamless injection molding process, the glossiness can reach 90 or more, the
brightness can reach 80 or more, and the pencil hardness can reach F or more. In addition, adding silicone
powder can reduce the surface friction coefficient of ABS, but the addition ratio needs to be controlled at
around 1%. And the ABS/PMMA alloy material without spraying can further improve the surface hardness,
making it reach H or above. The application of high gloss scratch resistant and spray free ABS material based
on high gloss seamless injection molding process is feasible in the field of injection packaging.
Key words: high gloss; scratch resistant; spray free ABS; high gloss seamless process; injection molding
