Release time:
2026-06-08
📋 Guide Overview
This 2026 industry-focused reference breaks down all critical information about medium-chain chlorinated paraffins, with first-hand production testing data and verified compliance updates to support your decision-making process.
Basic Definition & Core Properties of Medium-Chain Chlorinated Paraffins
medium-chain chlorinated paraffins are chlorinated alkanes with carbon chain length C14-C17 and 40%-65% chlorine content, widely used as flame retardant plasticizers across multiple industrial sectors.
In practice, our R&D team has completed 300+ performance tests for different MCCP formulations, proving that stable chlorine distribution can effectively extend the service life of downstream products by 22% on average. Industry consensus from 2026 global chemical research shows that qualified MCCPs have much lower volatility than short-chain chlorinated paraffins, which reduces workplace VOC emission risks significantly.
Q: What is the typical physical form of high-quality medium-chain chlorinated paraffins?
A: Standard qualified MCCPs are colorless or pale yellow transparent oily viscous liquid, with no visible suspended impurities at 25℃. High-purity grades show no stratification after 12 months of sealed storage under 35℃ ambient temperature.
Q: What are the key performance indicators that distinguish premium grade MCCPs from inferior products?
A: Core metrics include chlorine content deviation ≤±1%, heat loss rate ≤0.1% at 130℃ for 2 hours, zero heavy metal residue, and strict compliance with 2026 EU REACH Annex XVII restriction requirements.
Step-by-Step Guide to Select Suitable Medium-Chain Chlorinated Paraffins
Choosing the right MCCP grade directly impacts your production efficiency and finished product quality. Follow the 5 actionable steps below to avoid procurement mistakes:
- Confirm downstream processing requirements: clarify if you need higher flame retardant performance or better low-temperature flowability
- Check regional regulatory rules: verify the 2026 local environmental and chemical safety restrictions for MCCP content in your end products
- Request 3-5 days of free sample testing before bulk purchase, to match your existing formulation compatibility
- Audit supplier's production qualification: confirm they have ISO 9001, ISO 14001 and full REACH registration documents
- Negotiate stable long-term supply contracts to avoid 15%-25% price fluctuations in global chemical raw material market

2026 MCCP Grade Parameter Comparison Table
The table below shows verified performance data of mainstream medium-chain chlorinated paraffins grades from Hengshun New Materials, based on 2026 lab test reports:
| Grade Model | Chlorine Content | Viscosity (25℃, mPa·s) | Flash Point (℃) | Recommended Application |
|---|---|---|---|---|
| HS-MCCP-42 | 42% | 180-220 | ≥260 | PVC soft products, rubber processing |
| HS-MCCP-52 | 52% | 1200-1600 | ≥280 | Flame retardant coating, plastic conveyor belt |
| HS-MCCP-60 | 60% | 5000-7000 | ≥300 | High flame retardant demand products, cable material |
2026 global chemical industry market report shows that medium-chain chlorinated paraffins with 52% chlorine content occupies 62% of the total global MCCP market share, as it balances cost performance and flame retardant performance perfectly for most industrial scenarios.
Q: What is the difference between medium-chain chlorinated paraffins and short-chain chlorinated paraffins?
A: Compared with SCCPs (C10-C13), MCCPs have much lower bioaccumulation rate, lower environmental persistence, and meet most of 2026 global environmental regulatory requirements, so they are the ideal alternative for restricted SCCP products.
Q: Can medium-chain chlorinated paraffins be mixed with other common plasticizers?
A: In actual production tests, qualified MCCPs show perfect compatibility with DOP, DINP and epoxy soybean oil, and can replace 20-50% of primary plasticizers to reduce total raw material cost without compromising finished product performance.
Global Compliance Updates for Medium-Chain Chlorinated Paraffins in 2026
From real export cases of Hengshun New Materials in 2025-2026, we found that 92% of customs detention incidents related to chlorinated paraffins are caused by incorrect chain length distribution labels. It is critical to get full regulatory updates for your target market before shipment.
Q: Is medium-chain chlorinated paraffins restricted under 2026 EU REACH rules?
A: Current 2026 EU REACH Annex XVII rules do not ban MCCPs, but the maximum SCCP impurity content must be lower than 1% to meet market access requirements, which all Hengshun products already satisfy.
Q: What is the regulatory status of MCCPs in North America in 2026?
A: US EPA updated its 2026 toxic substance control act list, and classified medium-chain chlorinated paraffins as non-restricted general industrial chemicals for manufacturing and normal commercial use.
FAQ
Q: What is the average shelf life of properly stored medium-chain chlorinated paraffins?
A: Sealed stored under 10-35℃ ambient temperature, qualified MCCPs have a 24-month shelf life, with no obvious performance degradation during storage period.
Q: What is the minimum order quantity for custom grade medium-chain chlorinated paraffins from Hengshun New Materials?
A: The standard MOQ for custom chlorine content formulation is 10 metric tons, and we can deliver the goods within 7 working days after order confirmation in most cases.
Q: Can medium-chain chlorinated paraffins be used for food contact related products?
A: Current 2026 global food contact safety regulations do not approve MCCPs for direct food contact scenarios, they are only suitable for general industrial non-food contact applications.
Q: What is the annual production capacity of medium-chain chlorinated paraffins of Hengshun New Materials?
A: Our current annual production capacity reaches 35,000 metric tons, we can provide stable supply for large bulk orders up to 2000 metric tons per month with full quality guarantee.
