use::
- Perkadox? PD-50S-PS is mainly used for crosslinking silicone rubber.
- Silicone rubber containing Perkadox? PD-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.
- The recommended safe processing temperature (rheometer ts2 > 20 minutes) is 65°C and the typical cross-linking temperature (rheometer t90 approx. 12 minutes) is 90°C.
thermal stability::
- Organic peroxides are thermally unstable and self-accelerating decompositions.
- Self-accelerating decomposition temperature (SADT) of 140°F (60°C).
- Store at a maximum temperature of 86°F (30°C).
decomposition product: Major breakdown products include carbon dioxide, 1,3-dichlorobenzene, 2,4-dichlorobenzoic acid, and traces of 2,2',4,4'-tetrachlorobiphenyl.
Security and handling::
- Perkadox? PD-50S-PS is classified as "Reproductive Toxicity, Category 1B".
- When storing and handling, keep container tightly closed, out of direct sunlight and away from heat or ignition sources.
