use::
- Perkadox® OPC-50S-PS is mainly used for crosslinking silicone rubber.
- Silicone rubber containing Perkadox® OPC-50S-PS can be crosslinked without external pressure, such as hot air or/and infrared vulcanization.
- It can be easily mixed with silicone rubber in a two-drum mixer.
- Recommended additions are 1.1% - 2.3% of silicone rubber to obtain the desired degree of crosslinking.
norm::
- Appearance: gray-white uniform paste
- Density, 20°C: 1.18 g/cm³.
- Safe processing temperature (rheometer ts2 > 20 min): 65°C
- Typical crosslinking temperature (rheometer t90 approx. 12 min.): 90°C
decomposition product: The major breakdown products include carbon dioxide, 1,3-dichlorobenzene, 2,4-dichlorobenzoic acid, and traces of 2,2′,4,4′-tetrachlorobiphenyl.
Standard Packaging: Plastic drums for products with a net weight of 20 kg.
thermal stability::
- Organic peroxides are thermally unstable and self-accelerating decompositions.
- Self-accelerated decomposition temperature (SADT) of 60°C.
- Store at a maximum temperature of 30°C.
Security and handling::
- Keep containers tightly sealed and store and handle Perkadox® OPC-50S-PS in a dry, well-ventilated area away from heat or ignition sources and out of direct sunlight.
- Avoid exposure to reducing agents (e.g., amines), acids, bases, and heavy metal compounds (e.g., accelerants, desiccants, and metal soaps).
- Refer to the Safety Data Sheet (SDS) for detailed information on the safe storage, use and handling of the Perkadox® OPC-50S-PS.
statement denying or limiting responsibility::
- Users must determine for themselves in advance, through testing or other means, whether the Products are suitable for their intended use.
