Crosslinking

Key Crosslinking Parameters

To find applications in the crosslinking of elastomers, an organic peroxide must satisfy the following conditions:

• It must be safe to handle during transportation, storage and processing
• It must be compatible with the elastomer, to facilitate dispersion
• It must be stable enough to avoid premature crosslinking at compounding temperature
• The peroxide and its decomposition products must be non-toxic and meet the requirements of industrial hygiene
• It should react in such a way that the crosslinking is the only modification to the polymer that occurs

Some parameters are used to help choose a suitable peroxide for each application:

• Active Oxygen Content
• Half-life Temperature
• Minimum Cure Time
• SADT (Self Accelerating Decomposition Temperature)
• Maximum Storage Temperature
