Perkadox L-50S-ps is mainly used for the crosslinking of silicone rubbers.
• Perkadox L-50S-ps can easily be incorporated into a silicone rubber compound on a 2-roll mill.
• Safe processing temperature: 85°C (rheometer ts2 > 20 minutes).
• Typical crosslinking temperature: 105°C (rheometer t90 about 12 minutes).

Value Units Test Method / Conditions Density (at 20°C) 1.12 kg/m³ - - Thermal stability
- Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition.
- The lowest temperature at which self- accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT).
- The SADT is determined on the basis of the Heat Accumulation Storage Test.

Packaging & Availability
- Packaging Information
- Perkadox L-50S-ps is packed in a 20 kg pail.
Storage & Handling
- Shelf Life
- 6 months
- Storage Information
- Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time.
- To minimize the loss of quality, AkzoNobel recommends a maximum storage temperature (Ts max.) for each organic peroxide.
- When stored under these recommended storage conditions, Perkadox L- 50S-ps will remain within the AkzoNobel specifications for a period of at least six months after delivery.
- Storage and Handling Information
- Keep containers tightly closed. Store and handle Perkadox L-50S-ps in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room.
- Avoid contact with reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, driers and metal soaps).
