Description
Pigment Yellow 83 (CAS 5567-15-7) is a diazo organic pigment classified under C.I. 21108, commercially available under trade names including PY83 Yellow HR, PY83 Yellow HRE, and PY83 Yellow HRP. It carries no E-code designation and is identified by EC number 226-939-8 with molecular formula C36H32Cl4N6O8.
In plastics processing, PY83 provides strong yellow coloration with good heat stability, making it suitable for polyolefin and PVC compounding where consistent hue retention under processing temperatures is required. In printing inks and packaging applications, its high tinting strength allows formulators to achieve target color densities at reduced pigment loading, while its lightfastness supports outdoor-facing print applications.
PY83 is supplied as a dry powder solid and must comply with REACH registration requirements for European market supply. Procurement teams should confirm supplier documentation including Safety Data Sheets and technical data sheets specifying color strength, dispersibility characteristics, and batch consistency for quality-controlled formulation work.
