Perovion BCHPC P16 is a solid organic peroxide based on di(4-tert-butylcyclohexyl) peroxydicarbonate chemistry, supplied as a powder for use as an initiator in polymerization and thermoset curing processes. Perovion BCHPC P16 shows high reactivity at elevated temperatures combined with a low activation temperature and a relatively long pot life at ambient conditions, giving processors a favorable balance of stability and cure speed. Perovion BCHPC P16 is widely used for curing unsaturated polyester and methacrylic resins, as well as an initiator for the production of PVC, PVA, PVOH, and acrylics, making it a versatile choice across both thermoset and thermoplastic manufacturing routes.
Perovion BCHPC P16 Overview
Di(4-tert-butylcyclohexyl) peroxydicarbonate belongs to a class of organic peroxides known for combining a low activation temperature with good storage stability at ambient conditions. Perovion BCHPC P16 is supplied as a solid powder, giving formulators a stable, easy-to-handle initiator form suited to both thermoset resin curing and suspension or bulk polymerization processes across a range of reactor and mold configurations. This combination of reactivity and stability allows the product to be stored and handled with a relatively long pot life while still delivering efficient cure or conversion once the target process temperature is reached, reducing the risk of premature initiation during transport, warehousing, and everyday plant handling.
As a solid initiator, Perovion BCHPC P16 is added directly to resin systems or polymerization reactors according to the target cure or reaction temperature, typically starting from around 60°C and higher. In unsaturated polyester and methacrylic resin curing, Perovion BCHPC P16 supports thermoset composite manufacturing processes that require efficient cure at elevated and high temperatures, helping processors achieve shorter cure cycles without sacrificing part quality, dimensional stability, or surface finish.
Key Features
- Low Activation Temperature with High Reactivity: Perovion BCHPC P16 activates at a comparatively low temperature while still delivering high reactivity, supporting efficient cure and conversion in thermoset and polymerization systems across a range of production scales.
- Long Pot Life at Ambient Conditions: Despite its low activation temperature, this initiator offers a relatively long pot life at ambient temperature, giving processors a practical working window before cure begins.
- Solid Powder Form: Supplied as a powder, this grade simplifies handling, storage, and dosing compared with liquid formulations.
- Dual-Purpose Initiator: It functions both as a curing agent for unsaturated polyester and methacrylic resins and as an initiator for PVC, PVA, PVOH, and acrylics production.
- Suitable for Suspension and Bulk Polymerization: It is applicable to suspension and bulk polymerization processes, broadening its use across multiple polymer production routes spanning both thermoset composites and thermoplastic resin manufacturing operations of varying scale.
Typical Applications
Perovion BCHPC P16 functions as a thermally activated curing initiator for unsaturated polyester and methacrylic resin systems, supporting thermoset composite manufacturing at elevated and high temperatures starting from around 60°C. Its low activation temperature combined with high reactivity makes it well suited to processes requiring efficient cure within a defined temperature window.
Common end uses include thermoset composite curing for structural and semi-structural parts, as well as initiation for the production of PVC, PVA, PVOH, and acrylic polymers via suspension and bulk polymerization. It is also applicable to specialty resin systems requiring a solid initiator with a favorable balance of reactivity and storage stability, including applications where a long ambient pot life simplifies production planning.

Perovion BCHPC P16: Safety & Handling
Perovion BCHPC P16 should be handled in accordance with applicable safety procedures for organic peroxides. The product is classified as an oxidizing and thermally unstable material and requires appropriate storage, segregation, and handling measures to prevent accidental decomposition or contamination, particularly given its low activation temperature relative to many other solid peroxide classes. Users are advised to review the Safety Data Sheet prior to handling and to implement suitable personal protective equipment and engineering controls, including eye protection, chemical-resistant gloves, and adequate ventilation in the work area, especially during weighing, transfer, and dosing operations on the production floor.
Spills should be contained and cleaned up promptly using absorbent materials compatible with organic peroxides, and contaminated waste should be disposed of according to local regulations and destination-specific environmental requirements, particularly given the solid powder form of the product.
