- Peroxide Content: Approximately 75% (mass percentage)
- Active oxygen content: approximately 6.88% (mass percentage)
- Inhibitor: High-boiling-point aliphatic hydrocarbons
- Density (20°C): approx. 0.85 g/cm³
- Viscosity (20°C): approx. 1.7 mPa·s
- Refractive index (20°C): approx. 1.414
- Critical temperature (SADT): approx. 25°C
- Low-Temperature Storage Stability: Remains liquid at temperatures below -15°C
- Recommended storage temperature: -15°C to -5°C
- Maximum shipping temperature: 0°C
- Storage Stability (Activity): 3 months from the date of delivery
- 10 hours/1 hour/1 minute (0.1 m/benzene): 56/74/110°C
- Used in the polymerization of high-pressure ethylene, in combination with peroxides that offer higher thermal stability. The applicable temperature range is 130–190°C.
- Characteristics: Highly effective, liquid form, and easily miscible with high-boiling-point aliphatic hydrocarbons.
- For vinyl chloride, it can be used in bulk or suspension polymerization; the applicable temperature range is 50–65°C. Dosage: 0.04–0.1% as supplied.
- Suitable for the polymerization of other monomers, such as acrylonitrile, (meth)acrylates, and vinyl acetate, with an operating temperature range of 50–80°C. Dosage: 0.04–0.1% as supplied. Use in combination with peroxides that offer higher thermal stability to reduce residual monomer content in the polymer.
