- DHBP-50-WO is a colorless, free-flowing liquid composed of 50% 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane and white mineral oil.
- It is primarily used as a rheology modifier for polypropylene.
- Appearance: Colorless liquid
- Peroxide Content: Approximately 50% w/w
- Active oxygen content (calculated value): approx. 5.5% w/w
- Inerting Agent: White mineral oil
- Density (20°C): approx. 0.87 g/cm³
- Viscosity (20°C): approx. 29.1 mPa·s
- Refractive index (20°C): approx. 1.446
- Color Index (Hazen): approx. 20–40
- Miscibility: Immiscible with water; miscible with alcohols and esters
- Critical Temperature (SADT): Greater than 80°C
- Freezing point: below -5°C
- Recommended storage temperature: Not to exceed 40°C
- Storage stability after delivery date: 12 months
- Used to control the rheological properties of polypropylene within a temperature range of 200–220°C.
- Recommended usage: 0.01–0.2% w/w of the polymer, based on the product supplied.
- The use of DHBP-50-WO can reduce the molecular weight of polypropylene, making it easier to process and reprocess, while also increasing the melt flow index of the rheologically modified material.
- The documentation also includes information on the effects of peroxides used for polymer cross-linking and the impact of stabilizers on the efficiency of the degradation process.
- Standard packaging includes 800-kilogram plastic IBCs, 1,000-kilogram stainless steel IBCs, and 25-kilogram HDPE drums.
