Applications of Hexachloroethane in Industrial Manufacturing

Hexachloroethane is a specialty chlorinated compound serving as a key process aid in various industrial sectors. Our manufacturing expertise enables large-scale, high-purity production to support international clients in multiple critical downstream markets.

1. Metal Foundry Degassing for Aluminum and Magnesium Alloys

Metal casthouses and specialty alloy producers use hexachloroethane tablets as a primary degassing agent for light metal melts. Foundry operators introduce these tablets to molten aluminum and magnesium to reduce dissolved hydrogen and remove non-metallic inclusions. Hexachloroethane decomposes to release chlorine, which reacts with hydrogen and impurities, forming products separable as dross. This application supports automotive, aerospace, and electronics-grade alloy refining, demanding high process consistency during melt preparation and casting.

Industry compliance standards

• ASTM B962 – Standard Practice for Degassing Aluminum and Aluminum Alloys
• REACH Regulation (EC) No 1907/2006 Annex XIV (use in industrial sites – authorized conditions)
• ISO 9001:2015 for process and QC systems
• Chinese GB/T 8733—2010 Aluminum Alloy Castings

Typical usage ratio

• 0.5% – 2% by weight of metal batch, adjusted for melt temperature, alloy composition, and hydrogen content target

Downstream process integration

• Operators introduce hexachloroethane in tablet or powder form directly to molten metal after charging and alloying, prior to final cleaning, skimming, and pouring
• Degassing usually occurs after fluxing steps, in dedicated degassing stations or in crucibles, using plungers or injection lances

Final product types

• Aluminum alloy automotive wheels, chassis components
• Magnesium die-cast parts
• Aerospace casting billets
• Consumer electronic housings

2. Pyrotechnics and Smoke Munitions Manufacturing

Defense and pyrotechnic facilities utilize hexachloroethane as a chloride donor and smoke-producing ingredient in military screening devices, training grenades, and commercial smoke signaling products. The material forms the base for hexachloroethane-zinc (HC) smoke compositions. Formulators blend it with zinc powder and other select organic coolants, then press the mix into pellets or charge casings for deployment. On ignition, dense white smoke forms via zinc chloride vapor, meeting requirements for obscuration, visibility management, or marking operations under field deployment standards.

Industry compliance standards

• US MIL-STD-601D (Military Explosives)
• UN Recommendations on the Transport of Dangerous Goods – Model Regulations
• European Regulation 2017/852 (Restriction of use for civilian markets)
• ISO 17025 for laboratory batch testing

Typical usage ratio

• 45–65% by weight in HC smoke formulations; ratio customized per density and emission duration targets

Downstream process integration

• Mixing and granulation with zinc dust and binders; pressed into munitions charges, filled into canisters or grenade shells; subjected to QC testing for burn rate and smoke yield

Final product types

• HC smoke grenades for military and police use
• Artillery smoke shells
• Commercial marine distress signals
• Special effects stage smoke

3. Industrial Rubber Vulcanization Accelerator

Synthetic and specialty rubber product manufacturers deploy hexachloroethane as an auxiliary vulcanization accelerator or curing aid, especially in fluorinated and chloroprene elastomer processing. It acts as a chlorine donor and crosslinking agent, enhancing cure speed and network uniformity in complex formulations. Production engineers introduce it directly in compounding, often with other metal halides to achieve specified hardness and aging resistance in technical rubber goods demanded in oil-resistant, weatherproof, and specialty sealing applications.

Industry compliance standards

• ISO 23936-2 Elastomers for Oil & Gas Downstream Applications
• ASTM D2000 M2BG Specification for Rubber Products in Automotive Applications
• REACH Safety Data Sheet compliance (hazard labeling and workplace controls)
• Quality managed per IATF 16949 for automotive supply chains

Typical usage ratio

• 0.1 – 2 parts per hundred rubber (phr); precise loading determined by rubber base, vulcanization system, and physical properties target

Downstream process integration

• Dispersed during elastomer mixing and compounding (internal mixer/open mill), combined with traditional accelerators; forms part of batch before extrusion or molding, followed by controlled vulcanization in presses or autoclaves

Final product types

• Fluoroelastomer O-rings and seals
• Chloroprene weather gaskets
• Rubber linings for chemical tanks
• Automotive and industrial bushings

4. Laboratory-Scale Analytical Reagents for Trace Element Determination

Research and certified testing labs routinely apply high-purity hexachloroethane as an analytical standard and halogenation agent in trace element, microstructure, and spectrometric analysis. The compound serves as a halide source for sample preparation in neutron activation analysis, combustion analysis, and select polarographic or photometric determinations where interference-free halogen release is critical. Our production process ensures tightly controlled purity and particle size to minimize contamination of sensitive test protocols.

Industry compliance standards

• ISO/IEC 17025:2017 (General requirements for competence of testing and calibration laboratories)
• ASTM E1806 – Standard Practice for Sampling Steel and Iron for Determination of Chemical Composition
• EPA Standard Methods 3050 and 6010 (for sample prep in environmental analysis)
• Internal LIMS traceability and documentation (for research/customer audits)

Typical usage ratio

• Trace addition, typically 1–50 mg per analysis, adjusted for analytical sensitivity and test protocol

Downstream process integration

• Direct addition to sample matrices during digestion, fusion, or pyrolysis steps; supports halogenation and catalyst generation for spectroscopic measurement; applied in laboratory settings with calibrated balances and containment systems

Final product types

• Analytical test reports for steel, soil, or alloy trace contaminants
• Certified reference materials (CRM) for calibration
• Research documentation for industrial QC or environmental monitoring
• Standardized sample preparations for method accreditation
