Dongsung Chemex DCP 40
CHEMEX DCP 40 is a pre-dispersed dicumyl peroxide formulation containing approximately 40% active DCP on an inert mineral carrier (typically CaCO₃), supplied as a free-flowing powder or granules. This format delivers all the crosslinking efficiency of DCP with safer handling, easier dosing, and better dispersion compared to 99% DCP crystals—making it ideal for Indian manufacturers of rubber, EVA/PE foam, XLPE cable compounds, TPVs, and technical rubber goods.
Functional Features & Technical Detail
- 40% Active DCP on Carrier: Consistent peroxide content, with 60% CaCO₃ for safe, accurate dosing.
- Easy Handling: Powder/granule form reduces dust, improves flow, and minimizes risk of hotspots or dosing errors.
- Versatile Crosslinking Agent: Suitable for natural and synthetic rubbers, EVA, PE, XLPE, TPVs, and more.
- Uniform Dispersion: Formulated for even distribution and non-blooming behavior in rubber and polymer compounds.
- Safer Processing: Lower active content and inert carrier improve workplace safety and handling compliance.
Applications
CHEMEX DCP 40 is trusted by Indian and global processors for:
- Rubber Crosslinking: EPDM, EPR, HNBR, NBR, silicone rubber, and NR for automotive hoses, seals, gaskets, and profiles.
- EVA & PE Foam Crosslinking: Footwear, sports, construction foams with excellent compression set and rebound.
- XLPE & Cable Compounds: Crosslinks PE/EVA for wire and cable insulation/jacketing, improving heat and stress-crack resistance.
- TPVs, Shoe Soles, Seals: Used in thermoplastic vulcanizates, EVA/rubber shoe soles, and technical rubber goods.
- EPS, Foams, Flame-Retardant Systems: For foam structure, cell formation, and as a co-curing agent in composite and coating systems.
