should be strictly protected against irritation and potential carcinogenic risks, and protective instructions should be followed during operation.
Purchasing Recommendations:
Industrial mass production: Priority is given to Kunshan Ai Chao (high temperature resistance) or Hubei Xin Kang (flexible packaging)
Research purpose: TCI or Zhengzhou Aikem (high-purity small package)
Alternative solution: For biological staining, Oil Red O can be selected to reduce the risk of toxicity
Plastic coloring (Core Application)
Applicable materials: Polystyrene (PS), rigid PVC, organic glass (PMMA), ABS resin, polycarbonate (PC), etc
Performance advantages:
The color is bright and pure (bluish red), with high transparency
It has a heat resistance of up to 260°C, a weather resistance of grade 7, and an anti-migration resistance of grade 5
Typical products: electrical enclosures, cosmetic containers, toys, packaging materials
Daily chemicals and industrial products
Grease/candle coloring: Enhance visual recognition, use 0.02-0.05%
Ink and coatings: Ballpoint pen ink, clear varnish, enhancing color stability
Rubber products: toys, sealing parts dyeing
The field of biology and medicine
Biological staining: Lipid and triglyceride detection (can be replaced by oil red O)
Medical materials: Diagnosis of atherosclerosis, staining of dental impression materials
Toxicity risk
Hazard Indication: Xi (Irritating), T (Toxic)
Health hazard: Skin/eye irritants, suspected carcinogens (IARC Group 3)
Environmental toxicity: Extremely low water solubility (23μg/L), but biological accumulation should be prevented
Operation and Storage
Protective requirements: Wear chemical protective gloves and goggles to avoid inhaling dust
Storage conditions: Keep in a cool, well-ventilated place, sealed and protected from light, away from strong oxidants (such as nitric acid)
Fire extinguishing measures: water, carbon dioxide, dry powder (burning releases toxic nitrogen oxides)
