MACROLEX®
SOLVENT DYES
工程塑料溶剂染料
As early as the 1960s, Macrolex®为塑料着色的特殊需要开发了染料。工程塑料的工艺条件，如聚苯乙烯，ABS，PC，PMMA，PA等非常严重。Macrolex.®product range includes dyestuffs that are classified as disperse or solvent dyes.
Macrolex.®dyes are soluble in organic solvents, e.g., aromatics, esters, and chlorinated hydrocarbons. They are insoluble in water and dilute aqueous solutions of acetic acid or alcohol. Not being soluble in water and alcohol is important for use in consumer goods, food packaging, and children´s toys made of colored plastics, because the dye cannot bleed into the respective media.

Regulatory compliance
Macrolex.®染料符合许多应用领域的严格纯度要求。
- Directive 94/62/EC
- The overall concentration of lead, cadmium, mercury, or hexavalent chromium must not exceed 100 ppm by weight (0.01%).
- Restriction of the use of certain hazardous substances in electrical and electronic equipment
- Directive 2011/65/EU for Europe
- Similar regulations exist in Japan, the United States, and China
- EN 71-3 (Safety of toys: Migration of certain elements)
- EN 71-9（玩具的安全性：有机化学化合物的要求）。由于化学分类，不建议宏观黄色3G。
There are many national regulations, for example:
- Europe:Resolution AP (89) 1. The purity requirements are met by all Macrolex®dyes. Because of the chemical classification, Macrolex®黄色3g和macrolex®Black 2B are not recommended.
- United States:几乎所有的Macrolex.®dyes are approved for the coloring of PET in accordance with FDA regulations, at loadings of less than 0.20%.
- Japan:JHOSPA (Japan Hygienic Olefin and Styrene Plastics Association). The prerequisite for the use of colorants in food contact applications is a maximum of 100 ppm of lead, 50 ppm of mercury, and 100 ppm of cadmium.
- Australia:AS (Australian Standard) 2070.6 Plastic Materials for Food Contact Use: Limiting values for heavy metals and primary aromatic amines.
- 中国：GB9685用于食品容器和包装材料中添加剂的卫生标准。
