Applications & Use Cases
- ▸ Used as a high-temperature organic peroxide crosslinking agent for peroxide-cured elastomers such as EPDM, EPM, silicone, HNBR, and fluoroelastomers in molded and extruded rubber goods.
- ▸ Crosslinks polyethylene (PE) and EVA for wire-and-cable insulation, jacketing, and rotomolded parts, raising heat resistance and mechanical performance.
- ▸ Acts as a coupling/grafting and modification agent in controlled rheology and reactive-extrusion processes for polyolefins.
- ▸ Serves as a foaming/curing co-agent system component in cross-linked polyolefin foams used in automotive, footwear, and insulation.
- ▸ Functions as a radical initiator for thermoset and adhesive cure where a high decomposition temperature and low volatility are required.
