Applications and Crosslinking Performance
Trigonox 145-E85 is a bifunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Because it is supplied as a liquid solution on mineral oil carrier rather than as a solid, it can be metered and dosed directly into rubber and polyolefin compounds without a separate dispersion step.
The safe processing temperature for compounds containing Trigonox 145-E85 is 145°C (rheometer ts2 greater than 20 minutes), while the typical crosslinking temperature is 185°C (rheometer t90 about 12 minutes). Formulators should confirm these processing and crosslinking parameters against the latest technical data sheet for their specific rubber or polyolefin formulation before finalizing a production schedule.
Why Bifunctional Chemistry Matters for Trigonox 145-E85
Bifunctional peroxides such as Trigonox 145-E85 carry two peroxide groups per molecule rather than one, which formulators generally evaluate against monofunctional grades when a rubber or polyolefin compound needs a different crosslink density or cure profile. With an assay of 83.0-86.0% and a safe processing window up to 145°C, Trigonox 145-E85 is positioned to deliver consistent, repeatable crosslinking performance across production batches at the higher 185°C crosslinking temperature specified for this grade.
Because Trigonox 145-E85 is supplied as a liquid on mineral oil rather than as crystals or powder, formulators working with liquid metering and injection equipment can evaluate whether this grade simplifies handling compared with solid peroxide forms, which may help reduce dust exposure and simplify dosing accuracy on the production line.
What to Consider When Sourcing Trigonox 145-E85
When sourcing a bifunctional peroxide for rubber or polyolefin crosslinking, formulators typically evaluate assay, physical form, safe processing temperature, and crosslinking temperature, alongside consistent batch-to-batch quality. Working with a supplier that can provide current documentation and responsive technical support can help reduce qualification time when approving a new crosslinking peroxide for a production line.
Because this is a peroxide product supplied in liquid form on a mineral oil carrier, dosage, processing temperature, and crosslinking schedule should always be confirmed against the latest technical data sheet before finalizing a formulation, and small-batch trials are recommended prior to full-scale production runs.
General Handling and Storage Guidance
As an organic peroxide, this product should be kept in its original, tightly sealed container, stored in a cool, dry location away from direct sunlight and other heat sources, and handled according to standard organic peroxide safety practices.
Storage temperature limits, shelf life, and handling precautions vary by batch and packaging format, so formulators should always confirm current storage conditions and safety guidance against the latest technical data sheet and SDS for the specific batch of Trigonox 145-E85 they are working with.
