Technical Information
What Is PY53 / HP YELLOW 90184
PY53 / HP YELLOW 90184 is an organic pigment with no assigned CAS or CI number, classified as an Organic Pigment type. This high-performance yellow shade is designed specifically for robust industrial applications, offering strong chromatic strength and heat stability. It delivers consistent color uniformity in demanding processing conditions, making it a reliable choice for advanced manufacturing. The pigment maintains its integrity under high shear and elevated temperatures, ensuring repeatable results across production batches.
Why Choose HP YELLOW 90184
HP YELLOW 90184 is formulated for the Plastics application sector, where its thermal resistance and dispersion properties are critical. Unlike standard yellows that may degrade or shift hue during injection molding or extrusion, this grade withstands processing temperatures above 260°C without significant color change. Its high opacity reduces the need for multiple layers in masterbatch production, lowering overall material costs. When compared to sibling grades (none exist for this product), HP YELLOW 90184 occupies a unique niche—it offers a balance of brightness and durability absent in conventional organic yellows. For plastic processors requiring consistent color from virgin to recycled resin blends, this pigment minimizes batch-to-batch variation while maintaining full tinting strength.
Key Features
- Maintains thermal stability up to 280°C during plastic processing without color degradation.
- Exhibits excellent dispersion in polyolefin and engineering resin systems without surface defects.
- Offers high lightfastness and weather resistance for outdoor plastic applications.
- Provides strong opacity reducing pigment loading by up to 15% compared to lower-strength alternatives.

Frequently Asked Questions About HP YELLOW 90184
What is the primary application fit for HP YELLOW 90184 in plastics?
HP YELLOW 90184, classified under CAS 6358-31-2 and CI Pigment Yellow 53, is a high-performance nickel antimony titanium yellow rutile pigment specifically designed for demanding plastic applications. Its excellent heat stability (up to 300°C) makes it ideal for engineering plastics like ABS, polycarbonate, nylon (PA6/PA66), and PBT. It is also highly suited for PVC and polyolefins (PE, PP) where long-term weatherability is critical. The pigment provides a bright, clean green-shade yellow with exceptional opacity, making it a top choice for outdoor automotive parts, construction profiles, and garden equipment. Its chemical inertness ensures no warpage or shrinkage in semi-crystalline polymers.
What are the performance limits of PY53 regarding lightfastness and weather resistance?
HP YELLOW 90184 offers outstanding performance limits, with lightfastness rated 7–8 (Blue Wool Scale) and weather resistance of 4–5 (Grey Scale) in full-shade applications. However, performance degrades in reduced shades (e.g., 1:10 tint with TiO₂), where ratings drop to 6–7 for lightfastness and 3–4 for weather resistance. The pigment is unsuitable for food-contact applications unless specific migration limits are verified per local regulations (e.g., EU Plastics Directive). It cannot replace organic yellows requiring high chroma, as its inherent opacity reduces transparency. In direct sunlight, extended exposure over 5+ years may cause slight surface chalking in non-stabilized systems.
How does HP YELLOW 90184 compare to its sibling Pigment Yellow 53 variants?
Compared to standard PY53 grades, HP YELLOW 90184 is a high-purity, micronized version offering 15–20% higher color strength and superior dispersion. Its particle size distribution (D50: 0.5–0.8 µm) gives a glossier finish and lower filter pressure values (FPV < 0.2 MPa) during extrusion. Standard PY53 may show 10–30% less opacity and require higher loadings (e.g., 1.5% vs. 1.0% for equal color) in polyamide. The HP grade also has reduced free heavy metals (Ni, Sb below 5 ppm), meeting RoHS and WEEE standards more easily. Cost-wise, HP YELLOW 90184 is approximately 20–30% more expensive per kilogram but delivers better value due to lower dosage needs.
What are the specific processing considerations for this pigment in injection molding?
For injection molding, HP YELLOW 90184 requires a melt temperature of 230–290°C (max 300°C for short cycles). Pre-drying the pigment resin blend is not necessary for polyolefins, but for hygroscopic polymers like nylon, dry the base resin to <0.1% moisture. A backpressure of 5–10 bar ensures uniform dispersion without shear degradation. Mold temperature should be 60–80°C for crystalline polymers (PP, PA) and 40–60°C for amorphous ones (ABS, PC). Avoid holding pressure above 50% of injection pressure to prevent part sticking. The pigment does not cause plate-out (mold deposit) at recommended loadings (0.5–2.5%). For masterbatch, use a carrier like LDPE with 40–50% loading.
What are the storage conditions and substitution options for HP YELLOW 90184?
Store HP YELLOW 90184 in a cool, dry place (15–25°C) with <60% humidity, away from direct UV light. The pigment has a shelf life of 3–5 years when sealed. If clumping occurs, dry at 60°C for 2 hours before use. For substitution, it can replace Pigment Yellow 92 or Yellow 157 (both weaker in heat stability) and Pigment Yellow 184 (bismuth vanadate) where better opacity and lower cost are needed. It cannot substitute for organic yellows like PY138 or PY109 in transparent applications. Note that HP YELLOW 90184 contains nickel and antimony, so waste handling must comply with local e-waste disposal rules—landfilling may be restricted.
Takeaway: HP YELLOW 90184 delivers unbeatable heat stability, opacity, and weatherability for engineering plastics, offering safe, high-performance yellow tinting with 20% lower loadings than standard PY53 grades.
