Chlorinated paraffins

Description

1. Product Overview
Chlorinated paraffins (CPs) are high-performance secondary plasticizers and flame retardant additives, essential for imparting flexibility, durability, and fire resistance to industrial materials. Primarily used in PVC compounding, lubricants, and coatings, they deliver a cost-effective alternative to phthalates and phosphate esters without compromising mechanical stability. With global regulatory shifts favoring medium- and long-chain CPs, our product represents a strategically vital supply solution for manufacturers seeking compliant, high-efficiency formulations in a volatile raw material market.

2. Key Specifications & Technical Characteristics

• Chemical composition: Saturated n-paraffin hydrocarbons chlorinated to 42%, 52%, or 70% chlorine content (C14–C17 medium-chain / C18–C28 long-chain)

• Purity level: ≥99.5% active content; residual free carbon tetrachloride <0.01% (complies with REACH, RoHS)

• Physical characteristics:

  • Form: Clear to pale yellow viscous liquid (42% / 52%) or off-white resinous solid (70%)

  • Color (APHA): ≤150 (liquid grades)

  • Density (20°C): 1.15–1.26 g/cm³ (varies by chlorine content)

  • Viscosity (40°C): 150–1,500 cPs

  • Thermal stability: HCl release <0.15% at 175°C for 60 min

• Packaging options: 250 kg steel drums, 1,200 kg IBC totes, 20 MT flexitanks, or bulk ISO tanks

• Shelf life: 24 months in sealed, dry, cool storage (≤40°C, away from UV)

3. Core Industrial Applications

• Primary industries: PVC processing (construction & automotive), metalworking fluids, adhesives & sealants, rubber compounding, paints & coatings

• Specific use cases:

  • PVC flooring & cables: As secondary plasticizer – reduces compound cost by 15–20% vs. primary plasticizers while improving flame retardancy (LOI >28)

  • Metal cutting fluids: Extreme-pressure (EP) additive – increases tool life by 30% under heavy-load machining vs. sulfurized esters

  • Waterproofing membranes: Enhances flexibility at -20°C and resists migration/leaching better than phthalates

• Performance advantage: Superior chlorine stability (low thermal decomposition) allows higher processing temperatures (up to 190°C) without discoloration – critical for high-speed extrusion and injection molding.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production with SPC-controlled chlorination; batch-to-batch viscosity variance <±3%

• Supply reliability: Three geographically redundant manufacturing plants (Asia-Pacific, Europe, Americas); 98.5% on-time-in-full (OTIF) track record over 36 months

• Logistics capability: Dedicated hazardous material (Class 9, UN 2735) logistics network – door-to-door with real-time hazmat tracking

• Price competitiveness: Direct integration from base paraffin wax feedstock → fixed quarterly pricing available for contract volumes ≥500 MT/year

• Sustainability: Long-chain CPs (C18–C28) are not classified as PBT under Stockholm Convention; closed-loop HCl recovery system reduces carbon footprint by 22% vs. industry average

• Technical support: Free formulation auditing + TDS, MSDS, and regulatory compliance certificates (REACH, TSCA, UK-REACH, K-REACH) provided on request

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (MT) per product grade

• Bulk loading capacity: 20–24 MT per standard 20’ dry container (flexitank or 80 x 250 kg drums)
  *Drums: 80 drums × 250 kg = 20 MT net*
