4. Core Applications
- Polymer Material Modification
- Used as a crosslinking agent for polyolefins, polyurethanes and epoxy resins to improve the mechanical strength, heat resistance and solvent resistance of materials.
- Applied in the production of water-based adhesives and coatings to enhance adhesion and film-forming properties.
- Rubber Industry
- Serves as a secondary vulcanization accelerator for natural rubber and synthetic rubber (e.g., styrene-butadiene rubber, nitrile rubber), which can shorten vulcanization time and improve the elasticity and wear resistance of rubber products.
- Pharmaceutical Intermediate
- Key intermediate for the synthesis of sulfur-containing drugs, such as antibacterial agents, anti-inflammatory drugs and cardiovascular drugs, with high selectivity in the reaction process.
- Pesticide Manufacturing
- Used in the production of insecticides and fungicides with sulfur-containing structures, which can enhance the biological activity and environmental stability of pesticides.
- Other Fields
- Metal ion chelating agent for wastewater treatment, capable of complexing heavy metal ions (e.g., Cu²?, Hg²?) for removal.
- Raw material for the synthesis of functional dyes and pigments.
5. Storage and Transportation
Storage Conditions
- Store in a cool, dry and well-ventilated warehouse; the storage temperature should be controlled below 25°C, away from direct sunlight, heat sources and open flames.
- Keep the package tightly sealed to prevent moisture absorption and agglomeration; separate from strong oxidants, acids and alkalis during storage.
- Avoid long-term storage; it is recommended to use up the product within 12 months after opening the package.
Packaging Specifications
- 1 kg/bottle (brown glass bottle, sealed with aluminum foil); 5 kg/carton (inner PE bag); 25 kg/fiber drum (lined with double-layer PE film).
- Customized packaging is available according to customer requirements (e.g., 100 kg/bulk bag for industrial batch procurement).
Transportation Requirements
- Classified as non-hazardous chemical during transportation; comply with the transportation regulations of the country/region of departure and destination.
- Avoid violent collision, extrusion and rain exposure during transportation to prevent package damage and leakage.
- Transportation vehicles should be equipped with necessary fire-fighting equipment and leakage treatment tools.
Shelf Life
24 months under standard storage conditions (unopened original packaging).
6. Safety and Handling
- Hazard Identification
- Low toxicity; slight irritation to skin and mucous membranes upon prolonged contact.
- Non-flammable and non-explosive; decomposed at high temperature to produce trace amounts of sulfur-containing irritating gases.
- Handling Precautions
- Wear protective equipment such as chemical-resistant gloves, goggles and dust masks during operation to avoid inhaling dust or contacting skin and eyes directly.
- Operate in a well-ventilated environment; avoid eating, drinking or smoking during operation.
- Do not mix with strong oxidants (e.g., potassium permanganate, hydrogen peroxide) or concentrated acids to prevent chemical reactions.
- First-aid Measures
- Skin Contact: Immediately remove contaminated clothing and rinse the affected area with plenty of running water for 10–15 minutes; apply mild skin care cream if irritation occurs.
- Eye Contact: Lift the eyelids immediately and rinse with plenty of clean water or normal saline for 15 minutes; seek medical attention promptly if discomfort persists.
- Inhalation: Move the victim to fresh air immediately; keep the respiratory tract unobstructed. Seek medical help if coughing or chest tightness occurs.
- Ingestion: Drink plenty of warm water to induce vomiting (for conscious persons only); do not induce vomiting for unconscious persons and seek medical treatment immediately.
- Waste Disposal
- Unused products and contaminated packaging should be collected and disposed of by qualified hazardous waste treatment institutions in accordance with local environmental protection regulations.
- Do not discharge the product or its solution directly into water bodies, soil or sewers.
7. Additional Information
