Product Description

Product Description

Chemical Properties

• Chemical Name: Pigment Violet 23, abbreviated as PV23.
• Molecular Formula: C34H22Cl2N4O2, with a molecular weight of 589.47.
• Chemical Category: Belongs to the triphenodioxazine class of organic pigments.

Physical Properties

• Appearance: Usually a purple powder with bright colors, including red-shaded purple and blue-shaded purple.
• Relative Density: Generally ranges from 1.40 to 1.60, heavier than water.
• Specific Surface Area: 40-90 m²/g.
• Bulk Volume: 2.5-3.0 l/kg.
• Average Particle Size: 35-120 nm; some data show 15.234 μm.
• Oil Absorption: 30-60 g/100 g, with slight differences depending on product specifications.
• pH Value: Generally ranges from 5.5 to 8.0.

Performance Properties

• Lightfastness: Excellent. The lightfastness grade can reach 7-8 for full shade and 7-8 for tinted shade, making it resistant to fading during long-term outdoor use.
• Heat Resistance: Good thermal stability. Some products can withstand 160°C for 10 minutes at full shade, while others can reach 200°C or even 270°C.
• Solvent Resistance: Almost resistant to all organic solvents such as ethanol, with good stability in these solvents. The solvent resistance grade is usually 5.
• Acid and Alkali Resistance: Good resistance to acids (5% HCl) and alkalis (5% Na2CO3), generally reaching grade 5.
• Water and Oil Resistance: Both water permeability and oil permeability are grade 5, with good impermeability in water and oil, not easily dissolved or permeated by them.
• Migration Resistance: Good migration resistance, generally reaching grade 4, which means it is not prone to migration in media such as plastics, maintaining color stability.

Other Properties

• Tinting Strength: Strong tinting strength. It can provide satisfactory color depth with a small amount in almost all application media, and the tinting strength is usually 100±5%.
• Environmental Friendliness: Free of toxic chemical structures such as benzidine and heavy metals like lead and chromium, making it suitable for fields with high environmental requirements such as food packaging plastics and children's plastic toys.
