Why HP YELLOW 13155 Stands Out

HP YELLOW 13155 is a medium-to-reddish monoazo yellow specifically engineered for high-performance plastics coloration. With a heat stability ceiling of 260°C, it outclasses conventional diarylide yellows (PY12, PY13, PY17) that typically degrade above 200°C—making it the go-to choice for engineering thermoplastics like ABS, PET, and PBT where processing temperatures demand thermal headroom. Its calcium-laked monoazo structure (C.I. 13940) delivers best-in-class plasticizer resistance: migration rating of 5/5 in plasticized PVC after 72 hours at 70°C eliminates the bleeding issues that plague disazo pigments in flexible vinyl applications. The 35 m²/g specific surface area provides an optimal balance between dispersion ease and color strength development, enabling smooth masterbatch compounding at loadings up to 40%. For PP spin dyeing and HDPE blow molding, HP YELLOW 13155 maintains shade integrity through extended dwell times—a critical advantage over lower-molecular-weight alternatives. Where standard yellows fail under thermal and chemical stress, HP YELLOW 13155 delivers consistency manufacturers can rely on.

• Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
• Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
• Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
• Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
  where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”

Parameter Guidance

• Weather Resistance (Full Shade 4–5 / Tint 4): Adequate for indoor and limited outdoor use; for extended exterior exposure (automotive exterior, outdoor furniture), consider high-performance benzimidazolone or isoindolinone yellows.
• Light Fastness (Full Shade 6–7 / Tint 6): Strong indoor lightfastness supports retail packaging, appliance housings, and interior automotive trim where UV exposure is indirect but color retention is critical.
• Heat Stability (260°C): This is the key differentiator—260°C tolerance allows processing in engineering resins (ABS, PET, PBT, PC) without yellowing or shade shift, a temperature range inaccessible to most monoazo pigments.
• Specific Density (1.70 g/cm³): Moderate density ensures stable gravimetric feeding in masterbatch extrusion; lower than PY17 (1.85) which means more pigment particles per kilogram for equivalent color strength.
• Specific Surface (35 m²/g): The moderately high surface area delivers rapid color development during compounding but requires adequate wetting—pair with a compatible polymeric dispersant for optimal results.
• Oil Absorption (40 g/100g): Balanced oil demand permits high pigment loadings in masterbatch without sacrificing melt fluidity; typical loading range is 30–40% in PE carrier.
• Resistance to Acid & Alkali (Grade 5): Maximum chemical stability—safe for use in alkaline-cured systems, acid-catalyzed coatings, and cleaning-agent-exposed rubber parts.
• Resistance to MEK (4) & Toluene (4): Good solvent resistance for a monoazo pigment; suitable for solvent-borne coatings but validate under aggressive thinner blends for long-term storage stability.
• Migration Resistance PVC (Grade 5): Zero bleeding in both rigid and plasticized PVC—this is the standout property that makes PY62 the preferred yellow for flexible vinyl applications including cables, flooring, and automotive upholstery.

Frequently Asked Questions — PIGMENT YELLOW 62

Why is Pigment Yellow 62 preferred over diarylide yellows for engineering plastics?

Pigment Yellow 62 (PY62) delivers 260°C heat stability—60–100°C higher than typical diarylide yellows like PY12, PY13, and PY17. This thermal headroom is essential for engineering thermoplastics: ABS processes at 220–260°C, PET at 260–280°C, and PBT at 240–260°C. Diarylide pigments thermally decompose above 200°C, releasing dichlorobenzidine byproducts and causing shade drift, while PY62’s monoazo calcium lake structure remains stable. Additionally, PY62 achieves migration resistance of 5/5 in plasticized PVC where diarylide yellows typically bleed (grade 2–3). For manufacturers processing multiple polymer families, PY62 eliminates the need for polymer-specific yellow inventory.

What is the recommended pigment loading for PY62 in PP spin dyeing and HDPE masterbatch?

For PP spin dyeing (mass coloration of polypropylene fiber), PY62 is typically used at 0.5–2.0% pigment weight on fiber, with specific loading dependent on denier and target shade depth. Its 35 m²/g surface area ensures fine dispersion at the sub-micron level required for fiber spinning without filter pack pressure buildup. For HDPE masterbatch, load at 30–40% in LDPE or LLDPE carrier resin, targeting a let-down ratio of 2–4%. Pre-dry at 90°C for 2 hours before compounding. The pigment’s calcium lake structure provides inherent nucleation benefits in PP, potentially improving cycle times in injection molding applications.

How does PY62 perform in flexible PVC applications with high plasticizer content?

PY62 is the benchmark yellow for flexible PVC. Its calcium-laked monoazo structure provides migration resistance of 5/5 (no bleeding) in PVC plasticized with DOP, DINP, or DOTP at up to 50 PHR plasticizer loading, tested at 70°C for 72 hours per EN 20105-A03. This performance is unmatched by disazo yellows which bleed heavily under the same conditions. For PVC cable compounds requiring 105°C continuous service rating, PY62 maintains color stability throughout accelerated aging. In PVC flooring (calendering and pressing), it resists plasticizer exudation during the complete production-to-installation lifecycle. The pigment also passes common sulfide staining tests required for automotive interior PVC specifications.

What quality parameters should be verified when sourcing PY62 from pigment manufacturers?

When qualifying PY62 from any organic pigment manufacturer, verify these critical parameters: (1) Heat stability confirmed at 260°C for 10 minutes in ABS or HDPE with ΔE < 1.5—this validates the pigment's thermal integrity for engineering resin processing; (2) Migration resistance of 5/5 in plasticized PVC (50 PHR DOP, 70°C, 72h) to confirm suitability for flexible vinyl; (3) Specific surface area within 30–40 m²/g—deviations indicate inconsistent particle size distribution affecting dispersibility; (4) Light fastness of minimum 6–7 Blue Wool scale at full shade; (5) Calcium content within 3.5–5.5%—the calcium lake structure is integral to the pigment's performance and must be consistent batch-to-batch; (6) Compliance with EN 71-3, RoHS, and REACH for global market access.
