Daoming DCP 99
Daoming Dicumyl Peroxide 99 is a high-purity (≈99%) organic peroxide, supplied as a white crystalline powder or diamond-like crystals. It is based on bis(α,α-dimethylbenzyl) peroxide (CAS 80‑43‑3), and is used as a crosslinking agent for polyethylene (PE), EVA, CPE, EPDM, EPR, silicone rubber, and as a polymerization initiator for styrene and related monomers. Manufactured by Jiangsu Daoming Chemical—a specialist in dicumyl peroxide—this grade is engineered for consistent curing, reliable supply, and robust technical documentation.
Functional Features & Technical Detail
- High Purity Consistency: ~99% purity ensures repeatable crosslinking in PE, EVA, and elastomer compounds.
- Optimized Physical Form: Free-flowing white crystals or powder for easy dosing and dispersion in compounding lines.
- Versatile Crosslinker: Suitable for crosslinking a wide variety of polymers and elastomers, as well as for initiating styrene polymerization.
- Enhanced End-Product Performance: DCP crosslinking boosts thermal, chemical, and stress-crack resistance, and mechanical strength.
- Professional Manufacturing: Produced under ISO-based quality systems by Jiangsu Daoming Chemical, with strong technical and documentation support.
Applications
Daoming DCP 99 is trusted by Indian and global manufacturers for:
- Polyethylene & EVA Crosslinking: Used in foam sheets, footwear midsoles, insulation, and specialty construction foams—enabling 3D network formation for heat, chemical, and stress-crack resistance.
- Rubber Vulcanization: Crosslinking agent for EPDM, EPR, silicone rubber—improving heat aging, compression set, and mechanical properties for automotive, cable, and industrial parts.
- Styrene Polymerization & EPS: Initiator in styrene polymerization and expandable polystyrene (EPS) production, supporting cell structure and flame-retardant EPS.
Composite & Coating Applications: Curing agent for unsaturated polyester resins, composites, and as a modifier for recycled polyolefins and nanocomposites.
