Pigment Yellow 13 is a workhorse mid\u2011shade diarylide yellow used widely in plastics where reliable tint strength and balanced undertone are required. This guide consolidates practical, standards\u2011aware advice for PVC (plasticized and rigid), HDPE extrusion and blow molding, and polyolefin masterbatch\/TPE workflows.<\/p>\r\n\r\n\r\n\r\n

You\u2019ll find identity references, processing windows, migration and lightfastness context, and a neutral, replicable example of a plastics\u2011focused PY13 grade (HP YELLOW 1342) used in a PVC cable compound. Links to authoritative sources are included for verification and deeper study.<\/p>\r\n\r\n\r\n\r\n

What is Pigment Yellow 13?<\/h2>\r\n\r\n\r\n\r\n

Pigment Yellow 13 (Colour Index name C.I. Pigment Yellow 13; C.I. No. 21100; CAS 5102\u201183\u20110) is a diarylide yellow organic pigment. It typically delivers a mid\u2011shade yellow, positioned between the greener PY12 and the greener\u2011leaning PY17. Identity and synonyms are cataloged on the PubChem compound page under the same CAS and C.I. number, which also cross\u2011references \u201cDiarylide Yellow.\u201d See the registry profile in the PubChem entry for Pigment Yellow 13 for identifiers and context: PubChem \u2014 Pigment Yellow 13 (CAS 5102\u201183\u20110)<\/a>.<\/p>\r\n\r\n\r\n\r\n

Across plastics, PY13 is valued for its tinting efficiency and broad usability in PVC (cable insulation and flooring), HDPE (extrusion and blow molding), and in polyolefin masterbatches and TPEs where controlled processing protects hue and properties.<\/p>\r\n\r\n\r\n\r\n

Pigment Yellow 13 in PVC: cable insulation and flooring<\/h2>\r\n\r\n\r\n\r\n

In plasticized PVC (e.g., cable sheath compounds), Pigment Yellow 13 is prized for its balance of shade, dispersion, and migration resistance. Industry experience and vendor literature indicate that PY13 frequently shows better migration fastness than PY12 in plasticized systems, while in rigid PVC its anti\u2011bleed performance is typically comparable or improved due to the absence of plasticizer. Lightfastness near 1\/3 standard depth (with common TiO\u2082 reductions) generally falls in the mid\u2011to\u2011high Blue Wool range under sunlight exposure conditions described in plastics brochures. Methodologies and qualitative scales are well\u2011documented in the Heubach references on plastics coloration: see the Heubach brochure cited above for test frameworks and standard practices in PVC coloration.<\/p>\r\n\r\n\r\n\r\n

Cable and flooring color targets often reference DIN cable coloration context alongside RAL Classic shades as production targets. For instance, PVC cable sheathing frequently aligns to bright yellow shades such as RAL 1021 (Colza yellow). The official RAL Classic page provides the reference for this shade: RAL 1021 \u2014 Colza yellow (official RAL Classic)<\/a>. Orange\u2011leaning targets (e.g., RAL 2003) are also common in certain product lines. In practice, converters confirm shade with plaque or jacket swatches under standardized light and measure against RAL targets with calibrated instruments.<\/p>\r\n\r\n\r\n\r\n
