Polymer Initiators

Key Parameters

For the selection of the right organic peroxide and its concentration, the following parameters need to be considered:

• Technology of injection (liquid or solid, safety, etc.)
• Extruder temperature
• Extruder residence time
• Residues in the final resin and food grade regulations
• PP characteristics before degradation (homo, copolymer or heterophasic copolymer, MFI, additives type and level, etc.)
• Final PP6: MFI, MWD, controlled impact on mechanical properties
