Daoming DCP 40C
Daoming DCP 40C is a 40% dicumyl peroxide (DCP) masterbatch on calcium carbonate, engineered by Jiangsu Daoming Chemical for safe, efficient crosslinking of rubber, polyolefins, foams, XLPE cables, and technical plastics. Its pre-dispersed, free-flowing form ensures easy dosing, uniform dispersion, and safety in high-volume Indian manufacturing.
Functional Features & Technical Detail
- 40% DCP on CaCO₃: Stable, high-purity masterbatch with active oxygen ≤2.3%.
- Predictable Cure: Decomposition at ~120 °C, half-life: 10h@116 °C, 1h@135 °C, 1min@180 °C.
- Safe Handling: Powder/granule form reduces dust, improves weighing and feeding.
- Versatile Use: For rubber (EPDM, NR, NBR, HNBR, silicone), polyolefins, XLPE, EVA foams.
- Non-Blooming: Carrier system ensures uniform crosslinking and avoids blooming.
Applications
Daoming DCP 40C is used by manufacturers for:
- Rubber Compounding: Crosslinking in EPDM, silicone, NR, NBR, HNBR for hoses, seals, gaskets, and technical goods.
- XLPE & Cables: Enhances heat, chemical, and stress-crack resistance in cross-linked PE insulated power cables.
- Foam Plastics & EVA: Enables resilient, stable foams for footwear, sports, and construction.
- Shoes & EPS: Used in EVA/rubber shoe soles, EPS, and flame-retardant coatings for robust, durable output.
