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.
Dongsung Chemex DCP 99
Dongsung CHEMEX DCP is a high-purity dicumyl peroxide (DCP, CAS 80‑43‑3) engineered for use as a crosslinking agent and polymerization initiator in polyethylene (PE), EVA, ABS, EPS, and rubber. Available in solid (99%), liquid, and 40% carrier-based grades, CHEMEX DCP is a recognized global brand, now available in India through JITSY for cable, foam, footwear, and polymer processors seeking consistent DCP performance and robust technical documentation.
Functional Features & Technical Detail
- High-Purity DCP (≈99%): Ensures reliable, repeatable crosslinking and polymerization in PE, EVA, EPS, and elastomers with consistent active oxygen content.
- Multiple Handling Formats: Solid crystals, liquid, and 40% powder on CaCO3 carrier for compounding flexibility and safe dosing in various equipment.
- Efficient Crosslinking Agent: Supports robust foam formation, cable insulation, rubber vulcanization, and EPS expansion with superior thermal, chemical, and mechanical properties.
- Proven Decomposition Profile: Well-documented half-life and SADT data enable predictable cure design and safe processing windows.
- Trusted Global Brand: Produced in Dongsung's dedicated DCP plant in Yeosu, Korea, with ISO-based quality systems and full regulatory compliance for Indian industry.
Applications
Dongsung CHEMEX DCP 99% is trusted by leading Indian and global manufacturers for:- EVA & PE Foam Crosslinking: Enables resilient, durable foam for footwear, sports goods, and construction applications with excellent compression set and recovery.
- XLPE & Cable Insulation: Delivers superior heat, chemical, and environmental stress-crack resistance in crosslinked PE/EVA cable jacketing and insulation.
- Rubber Vulcanization: Used in EPDM, natural rubber, NBR, and technical rubber goods for automotive hoses, seals, gaskets, and industrial components.
- EPS & Styrenic Polymerization: Acts as a foaming aid and free-radical initiator for EPS, improving cell structure and flame-retardant performance.
- Composite & Coating Curing: Initiates crosslinking in unsaturated polyester resins, specialty coatings, and recycled polyolefin blends.
Technical Support & Application Guidance
JITSY works closely with processors to:- Select appropriate CHEMEX DCP grades (solid 99%, liquid, or 40% powder) for specific PE/EVA, rubber, or EPS formulations.
- Interpret general half-life and decomposition concepts from Dongsung and independent DCP literature for local processing conditions.
- Provide reformulation support for transitioning between DCP sources or optimizing cure profiles.
- Coordinate direct technical contact with Dongsung when specialized assistance is needed.
Quality Assurance, Traceability & Regulatory Support
CHEMEX DCP supplied by JITSY is sourced from authenticated Dongsung channels, delivered in sealed, labeled packaging with batch identification for traceability. Internal QA and documentation procedures support customer audits, regulatory filings, and product stewardship requirements in automotive, cable, building materials, and export-oriented industries across India.Related Products & Technical Alternatives

Then the question arises: where’s the content? Not there yet? That’s not so bad, there’s dummy copy to the rescue. But worse, what if the fish doesn’t fit in the can, the foot’s to big for the boot? Or to small? To short sentences, to many headings, images too large for the proposed design, or too small, or they fit in but it looks iffy for reasons.
A client that’s unhappy for a reason is a problem, a client that’s unhappy though he or her can’t quite put a finger on it is worse. Chances are there wasn’t collaboration, communication, and checkpoints, there wasn’t a process agreed upon or specified with the granularity required. It’s content strategy gone awry right from the start. If that’s what you think how bout the other way around? How can you evaluate content without design? No typography, no colors, no layout, no styles, all those things that convey the important signals that go beyond the mere textual, hierarchies of information, weight, emphasis, oblique stresses, priorities, all those subtle cues that also have visual and emotional appeal to the reader.
