Main Areas Of Application

Rubber Industry

In the rubber industry, N, N'-dinitrosopentamethylenetetramine is used as a blowing agent to manufacture microporous rubber products. These products possess excellent properties such as light weight, thermal insulation, sound insulation, vibration damping, and cushioning, and are widely used in the production of automobile tires, shoe soles, sealing strips, sound insulation materials, vibration reduction pads, and other rubber products.
Through the foaming process, the density of rubber products decreases, reducing weight while maintaining good physical properties and chemical stability.

Plastic Industry

In the plastic industry, N, N'-dinitrosopentamethylenetetramine is also used as a blowing agent. It is used to produce microporous plastics, such as foamed products of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and other plastics. These foamed products possess features like lightweight, thermal insulation, sound insulation, vibration damping, etc., and are widely applied in packaging materials, construction materials, automotive interiors, household appliances, sports goods, and more. The foaming process reduces the weight of plastic products while improving their thermal insulation, sound insulation, and cushioning performance.

Other Application Fields

Besides the rubber and plastic industries, N, N'-dinitrosopentamethylenetetramine also has potential application value in other fields. For example, it can be used as an additive or raw material in the explosive, pesticide, pharmaceutical intermediates, coatings, inks, paper, textiles dyeing and printing industries, to improve product performance or meet specific production needs. However, these application areas require further research and exploration.

Toxicity and Safety

Toxicity: This compound has moderate toxicity, with acute toxicity LD50 of 940 mg/kg (oral, rat).
Health Hazards: Thermal decomposition can release toxic nitrogen oxide fumes. Inhalation or ingestion may cause harm to human health.
Safety Information: Keep away from heat sources, avoid contact with oxidizers, acids, and bases. Ensure containers do not leak during storage and transport, and avoid contact with flammable substances or fire sources.

Emergency Handling and Protection Measures

Leak Emergency Handling
Isolate the leak-contaminated area and restrict access. Cut off fire sources. Emergency personnel should wear self-contained breathing apparatus and fire protection suits.
Do not touch the leaking material directly. Use water to wet it down, collect the material with non-sparking tools into a closed plastic container or cardboard, and dispose of or transport it to a waste disposal site.

Protection Measures
When there may be contact with its dust, wear self-absorbing filter dust masks. If necessary, wear an air respirator. For eye protection, wear safety goggles. For body protection, wear breathable protective clothing. Wear anti-penetration gloves for hand protection.

First Aid Measures
For skin contact, remove contaminated clothing and wash the skin thoroughly with soap and water. For eye contact, lift eyelids rinse with running water or saline solution, and seek medical attention.
If inhaled, remove to fresh air immediately, and keep the airway open. If breathing is difficult, administer oxygen; if breathing stops, perform artificial respiration and seek medical attention. If ingested, drink plenty of warm water, induce vomiting, and seek medical attention.

In conclusion, N, N'-dinitrosopentamethylenetetramine is an important blowing agent extensively used in the plastic industry. However, during its use, attention should be paid to its toxicity and safety issues to ensure the safety of personnel and the environment.
