Overview
Perkadox 14S-FL is a bifunctional peroxide supplied as slightly yellow flakes, used for the crosslinking of natural rubber, synthetic rubbers, and polyolefins. Buyers sourcing this product for rubber compounding typically value its excellent scorch safety, which under certain conditions allows one-step mixing rather than a separate curing stage. Because it functions across polymer production, polymer crosslinking, and polymer recycling market segments, Perkadox 14S-FL is used by rubber compounders, polyolefin processors, and composite material manufacturers who need a reliable bifunctional peroxide with a well-defined safe processing window.

Applications of Perkadox 14S-FL Across Market Segments
Perkadox 14S-FL can be used for the market segments of polymer production, polymer crosslinking, and polymer recycling, with their different applications and functions. As a bifunctional peroxide, it is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Rubber compounds containing this grade have excellent scorch safety, which supports more efficient production scheduling for compounders who need predictable cure onset.
Why Scorch Safety and One-Step Mixing Matter
The scorch safety profile of the product means the compound resists premature curing during mixing and processing, reducing the risk of scrap batches on the production floor. Under certain conditions, one-step mixing is possible with this grade, which can simplify a compounder’s process flow compared to peroxides that require separate incorporation and curing stages.
Why Sourcing Consistency Matters for Buyers
Crosslinking performance in rubber and polyolefin compounding depends on consistent assay and particle form from batch to batch. A minimum assay of 98.0% is specified for Perkadox 14S-FL, and buyers running high-volume rubber or polyolefin lines typically request certificates of analysis to confirm each shipment meets this specification before it enters production. Variation in active peroxide content can shift the safe processing temperature and crosslinking temperature away from the reference values of 135°C (ts2 greater than 20 minutes) and 175°C (t90 about 12 minutes), which in turn affects scorch margin and cure cycle planning.
For rubber compounders and polyolefin processors running continuous production schedules, supply chain reliability is just as important as technical specification. Working with a supplier that can provide consistent lot-to-lot quality and documentation helps reduce the risk of production delays tied to organic peroxide availability.
What to Consider When Sourcing Perkadox 14S-FL
Buyers evaluating this product for a new rubber or polyolefin formulation should confirm that the safe processing temperature and typical crosslinking temperature fit their existing mixing and curing equipment, and request the safety data sheet to plan for correct storage, transport, and handling as an organic peroxide. Since flake-form peroxides can behave differently from paste or liquid grades during dosing, sourcing managers should also confirm compatibility with their existing metering or weighing equipment.
Buyers moving to Perkadox 14S-FL from another bifunctional peroxide grade are encouraged to request technical guidance on dosage levels, since scorch time and cure rate can differ between grades even at similar assay levels. Confirming packaging options and minimum order quantities against production volume is also recommended before large-scale adoption.
General Handling and Storage Guidance
As with other organic peroxide products, Perkadox 14S-FL should be stored in a cool, well-ventilated area away from direct sunlight, incompatible materials, and sources of contamination. Containers should remain tightly closed when not in use, and any spilled material should be handled according to the safety data sheet to avoid decomposition risks associated with concentrated organic peroxides.
Personnel handling this product should use appropriate personal protective equipment and follow site-specific procedures for organic peroxide storage segregation. Buyers new to handling flake-form bifunctional peroxides are encouraged to review the full safety data sheet and consult applicable transport regulations before shipment.
