- CH-50-WO is a colorless liquid consisting primarily of approximately 50% 1,1-Di(tert-butylperoxy)cyclohexane, which has been desensitized with white oil.
- This cyclohexane-cyclopropanone ether compound is used as a free-radical initiator for the polymerization of monomers (e.g., styrene).
- Appearance: Colorless liquid.
- Peroxide Content: Approximately 50% w/w.
- Active oxygen: Approximately 6.14%.
- Antisensitizer: White oil (w/w).
- Density (20°C): Approximately 0.90 g/cm³.
- Viscosity (20°C): approximately 33 mPa·s.
- Refractive index (20°C): approximately 1.454.
- Explosion hazard temperature: approximately 70°C.
- Cold storage stability: below -20°C.
- Recommended storage temperature: below 30°C.
- Stability (activity) from the date of delivery: 6 months.
- This product complies with the ElektroG standard (EU Directives: RoHS 2002/95/EG, WEEE 2002/96/EG).
- Used as a polymerization initiator for styrene.
- Temperature range: 100–140°C.
- Recommended usage level: 0.02–0.1% (as is).
- Special Advantages: Reduces residual monomer content; does not react with chain modifiers (e.g., mercaptan alcohols); does not undergo hydrolysis in alkaline media.
- Recommended for use in combination with more reactive peroxides (e.g., tert-butylperoxy 2-ethylhexanoate).
- Potentially detectable decomposition products: acetone, tert-butanol, hexanone.
- 25-kilogram HDPE plastic drums.
