Product Introduction
Trichloroethylene (abbreviated as TCE), CAS No. 79-01-6, is a colorless and transparent liquid with a chloroform-like aromatic odor, non-flammable with vapor that is not readily explosive. Industrially, it is produced via the acetylene chlorination process or the chlorination/cracking of 1,2-dichloroethane. TCE has extremely strong solvency for oils, waxes, resins, and asphalt, with a boiling point of approximately 87°C, low surface tension, good penetrating ability, and non-flammability, making it one of the highest-performing solvents for metal degreasing and cleaning (particularly vapor degreasing processes), with fast drying and no residue after cleaning. The product must have amine-based or epoxy-based stabilizers added to inhibit decomposition and acid formation under the influence of light, heat, metal, and oxygen, thereby avoiding corrosion of equipment and workpieces.

Product Applications
- Metal Degreasing and Cleaning: Used as a vapor degreasing and immersion cleaning solvent for removing oil and grease from hardware components, bearings, motors, and precision parts;
- Electronic Cleaning: Used for flux removal and degreasing of printed circuit boards, electronic components, and optical parts;
- Dry Cleaning and Textiles: Used as a dry cleaning solvent and textile stain remover;
- Extraction and Solvent Applications: Used for extraction of oils/fats, fragrance compounds, and pharmaceutical ingredients, as well as a solvent for coatings and adhesives;
- Chemical Intermediate: Used to produce monochloroacetic acid, vinyl chloride derivatives, and raw materials for fluorinated refrigerants such as HFC-134a.
Packaging, Storage & Transportation
Packaging: Standard packaging in 300kg galvanized iron drums; for large volumes, shipped in bulk via 1000kg IBC totes, ISO tank containers, or tank trucks.
Storage: Classified as a Class 6 toxic substance, UN No. 1710. Must be stored in a cool, well-ventilated, light-protected warehouse dedicated to hazardous materials, with warehouse temperature not exceeding 30°C, avoiding direct sunlight exposure (light exposure accelerates decomposition and acid formation). Must be strictly stored separately from oxidizing agents, strong alkalis, and reactive metal powders (aluminum, magnesium powder) — never store together, as TCE may react violently upon contact with aluminum powder or strong alkalis. Containers must be sealed to prevent moisture absorption; for long-term storage, acidity and stabilizer content should be periodically tested.
Transportation: Transported in accordance with Class 6 toxic substance regulations. Handle gently during loading and unloading to prevent packaging damage; forced ventilation is mandatory at the work site, and personnel must wear self-priming filter-type respirators and solvent-resistant gloves — this product has a high vapor density and readily accumulates in low-lying areas, so inhalation must be avoided and unprotected work in confined spaces is strictly prohibited.
Product Advantages
- Stable supply sources with long-term spot inventory available, suitable for large-volume foreign trade orders;
- Stable product purity with minimal batch-to-batch variation, suitable for downstream deep-processing production;
- Backed by a comprehensive chemical supply chain system, enabling one-stop procurement combined with multiple categories of chemical raw materials.
