ABS POWDER KUMHO HR-181
Kumho ABS HR-181 (Powder Grade) – ultra-fine ABS powder with excellent solubility and impact-boosting rubber content, designed for high-gloss solvent-borne coatings, ABS/PC alloy masterbatch and powder-bed processes.
Sold by container only: 22.00 mt/container. Quantity = number of containers.
Key Benefits
| Benefit | Why it matters |
|---|---|
| Fine particle size (~80 μm D50) | Disperses rapidly in ketone/ester solvents or polymer melts, leaving no fisheyes. |
| High rubber content (~35 wt % BD) | Adds impact toughness when blended into PC, PVC or SAN matrices. |
| Fast dissolution & low gel | Ideal as a binder for metallic/pearlescent automotive paints and gravure inks. |
| Neutral off-white colour | Minimises tint when tinting or pigmentation is required. |
| Consistent bulk density (≈ 0.35 g/cm³) | Predictable feed for powder-bed fusion and dry-blend compounding. |

Applications & Compliance
Typical Applications
-
High-solids ABS basecoat / topcoat for consumer electronics, toys and appliance panels.
-
ABS/PC or ABS/PVC masterbatch – boosts impact while maintaining gloss.
-
Powder-bed fusion (SLS/MJF) feedstock where a tougher, lower-warpage ABS is required.
-
Adhesive & putty modifier – improves flexibility and crack resistance in PVC cements, tile grouts.
-
Metallic paste carrier for vacuum-metallised trims and cosmetic closures.
Compliance & Handling
-
Conforms to RoHS III (EU 2015/863) – no Pb, Cd, Hg, Cr VI, PBB, PBDE above limits.
-
Listed as UL 94 HB when pressed into standard 1.5 mm plaques.
-
Supplied in 20 kg moisture-barrier paper bags; store < 35 °C, < 65 % RH.
-
Dry at 70 °C for 2 h before use (critical for powder-bed applications).
Kumho ABS HR-181 bridges the gap between pellet ABS and specialty acrylic resins – offering formulators a fast-wetting, impact-tough powder that keeps finishes bright and parts resilient.
