appliance:
- Perkadox OPC-50S-PS-MM is mainly used for crosslinking of silicone rubber.
- Silicone rubber containing Perkadox OPC-50S-PS-MM can be crosslinked without external pressure (e.g., hot air or/and infrared vulcanization).
- Perkadox OPC-50S-PS-MM can be easily mixed with silicone rubber in a two-drum mixer.
- The recommended safe processing temperature (rheometer s2 > 20 minutes) is 65°C and the typical crosslinking temperature (rheometer t90 about 12 minutes) is 90°C.
- To obtain the desired degree of cross-linking, the recommended addition level of Perkadox OPC-50S-PS-MM is 1.1-2.31 TP3T of silicone rubber.
padding:
- Moisture: 1.5% max.
intensity:
- Density, 20C: 1.18g/cm3
thermal stability:
- Perkadox OPC-50S-PS-MM is an organic peroxide, which is thermally unstable and self-accelerating.
- Self-accelerated decomposition temperature (SADT) of 60°C.
Main decomposition products:
- Major decomposition products include carbon dioxide, 1,3-dichlorobenzene, and traces of 2,2',4,4'-tetrachlorobiphenyl.
Packaging and transportation:
- In North America, Perkadox OPC-50S-PS-MM is shipped in non-recyclable cartons with a net weight of 1 lb of product per bag.
- Other areas are peroxide products in barrels of 20 kg paste.
