Trigonox 101-45B-PD is a dialkyl peroxide supplied as a 45% active ingredient on CaCO3 carrier, formulated for easy dispersion in elastomer compounds with controlled dusting. Rubber compounders sourcing Trigonox 101-45B-PD benefit from a free-flowing powder form that simplifies handling and metering compared to liquid peroxide systems.

Trigonox 101-45B-PD Applications
Applications
This peroxide is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins. Rubber compounds containing it have excellent scorch safety, which gives compounders a wider processing window during mixing and extrusion before the crosslinking reaction begins.
Why Compounders Choose Trigonox 101-45B-PD
The CaCO3 carrier system in this peroxide is specifically designed to support easy dispersion in an elastomer compound while keeping dusting under control during weighing and mixing. For rubber compounders running natural rubber, synthetic rubber, or thermoplastic polyolefin formulations, this combination of dispersibility and scorch safety supports more consistent crosslink density across production batches.
Because the assay is standardized at 44.0-46.0% active ingredient, formulators can calculate peroxide loading for a target crosslink density with predictable dosing, rather than adjusting for batch-to-batch variation in active content.
Sourcing Trigonox 101-45B-PD for Rubber and Elastomer Production
Compounders evaluating Trigonox 101-45B-PD alongside other organic peroxide curing systems typically confirm scorch safety requirements for their specific mixing and extrusion equipment, along with compatibility with any co-agents already used in the formulation. Because this peroxide is supplied as a free-flowing powder rather than a liquid, dosing equipment calibrated for powder handling should be confirmed before switching from a liquid peroxide system.
Formulators new to powder-form peroxides sometimes ask how storage and handling differ from liquid systems. Powder peroxides on an inert carrier such as CaCO3 generally require dry storage away from heat sources and should be kept in their original packaging until use, consistent with standard organic peroxide handling practice. Compounders should always consult the current safety data sheet for storage temperature limits and shelf life specific to their production environment.
Compatibility testing with existing co-agents, fillers, and other curatives in a rubber formulation, evaluated using methods such as ASTM D297, is a standard step before switching peroxide suppliers or grades. Even when the assay and carrier type match a previous product, small differences in particle size distribution or carrier grade can affect dispersion behavior in a specific mixing process, so a short trial batch is generally recommended before a full production changeover.
