Applications:
- Perkadox® OPC-50S-PS is primarily used for the cross-linking of silicone rubber.
- Silicone rubber containing Perkadox® OPC-50S-PS can be cross-linked under conditions without external pressure, such as hot air and/or infrared curing.
- It can be easily blended with silicone rubber using a twin-roll mixer.
- The recommended addition level is 1.1%–2.3% of the silicone rubber to achieve the desired degree of crosslinking.
Specifications:
- Appearance: Grayish-white, uniform paste
- Density at 20°C: 1.18 g/cm³
- Safe processing temperature (rheometer ts2 > 20 minutes): 65°C
- Typical crosslinking temperature (rheometer t90 ≈ 12 minutes): 90°C
Decomposition Products: Major decomposition products include carbon dioxide, 1,3-dichlorobenzene, 2,4-dichlorobenzoic acid, and trace amounts of 2,2',4,4'-tetrachlorobiphenyl.
Standard Packaging: 20 kg net weight in plastic drums.
Thermal Stability:
- Organic peroxides are thermally unstable substances that undergo self-accelerating decomposition.
- The self-accelerating decomposition temperature (SADT) is 60°C.
- The maximum storage temperature is 30°C.
Safety and Handling:
- Keep the container tightly sealed. Store and handle Perkadox® OPC-50S-PS in a dry, well-ventilated area, away from heat sources or ignition sources, and avoid direct sunlight.
- Avoid contact with reducing agents (such as amines), acids, bases, and heavy metal compounds (such as accelerators, driers, and metal soaps).
- For detailed information on the safe storage, use, and handling of Perkadox® OPC-50S-PS, please refer to the Safety Data Sheet (SDS).
Disclaimer:
- Users must independently determine in advance, through testing or other means, whether the product is suitable for their intended use.
