Description

1. Product Overview
Organosilicon Residue is a high-value secondary raw material recovered from polysilicon and silicone production processes, consisting primarily of chlorosilanes, siloxanes, and silicon polymers. Its primary industrial use is as a cost-effective feedstock for synthesizing downstream silicone monomers, hydrophobic agents, and industrial-grade silicone oils. The key value proposition lies in delivering 30-45% material cost savings versus virgin organosilicon compounds while maintaining consistent reactivity for mid-tier applications. It is strategically important in the market as global silicone demand outpaces primary supply, positioning recycled residues as critical to supply chain resilience and circular economy mandates.

2. Key Specifications & Technical Characteristics

  • Chemical Composition: Mixed organosilicon compounds including dimethyldichlorosilane, trimethylchlorosilane, cyclic siloxanes (D3-D6), and high-boiling polysiloxane oligomers. Total Si content: 28-35%
  • Purity Level / Grade: Industrial Recovery Grade; Hydrolyzable chloride content ≤2.5%; Active siloxane content ≥75%
  • Physical Characteristics:
    • Form: Viscous liquid to semi-solid slurry
    • Color: Light yellow to dark brown
    • Density: 0.98-1.15 g/cm³ at 25°C
    • Viscosity: 200-2000 cP at 25°C
    • Flash Point: ≥60°C
  • Packaging Options: 200L HDPE drums with nitrogen blanket, 1MT IBC totes, ISO tank containers for bulk
  • Shelf Life: 6 months under sealed, dry, nitrogen-protected storage at ≤30°C

3. Core Industrial Applications

  • Primary Industries: Silicone rubber compounding, construction sealants, textile auxiliaries, defoamer manufacturing, and metallurgical processing
  • Specific Operational Use Cases: Used as base stock for methyl silicone oils, as water-repellent additive in cement and mortar formulations, as reducing agent in magnesium production, and as raw material for low-spec RTV silicone production
  • Performance vs. Alternatives: Outperforms virgin DMC in non-critical applications by reducing input cost per kg of final silicone by 30-45% with minimal reformulation. Offers superior thermal stability versus hydrocarbon-based alternatives in defoamer use
  • Efficiency / Cost Advantages: Lowers raw material procurement cost, reduces hazardous waste disposal fees for generators, and shortens lead times compared to virgin siloxane imports. Enables 15-20% reduction in finished product COGS for mid-grade sealants

4. Competitive Advantages

  • Quality Consistency: Batch-level GC-MS analysis and viscosity control with Certificate of Analysis provided; deviation <5% on key parameters
  • Supply Reliability: Sourced from 3 audited polysilicon facilities with aggregate capacity >800 MT/month; 12-month supply contracts available
  • Logistics Capability: DG Class 3 handling expertise, UN-certified packaging, and established routes from East China ports. Incoterms: FOB, CFR, CIF globally
  • Price Competitiveness: 35-50% below virgin organosilicon monomer spot prices; volume-tiered pricing for 100MT+ contracts
  • Sustainability Benefits: Diverts 100% of material from incineration/landfill; each MT used reduces CO₂e by ∼2.8 MT vs. virgin production. Supports ISCC PLUS and ISO 14021 claims
  • Technical Support: Full SDS, TDS, and application formulation guidance. Dedicated technical team for process integration trials

5. Commercial & Supply Information

  • Minimum Order Quantity (MOQ): BULK 20MT
  • Loading Capacity: 18-20 MT per 20ft container depending on packaging type
