According to U.S. Code of Federal Regulations (CFR) 49 §173.306, metal aerosol cans must not exceed an internal pressure of 180 psig at 54.4°C (130°F), and the container must be able to withstand at least 1.5 times the thermal equilibrium pressure without rupture or deformation.

Testing Method: · Place the finished aerosol can in water; · Gradually inflate the can using a dedicated pressurizing device; · Record the pressure at which the dome permanently deforms or bursts. Judgment Criteria: Generally, a pressure of at least 1.2 MPa is required, with specific standards depending on the intended use.

The top and main body of an aerosol can are called: 1. The top structure is called the dome. 2. The transition between the dome and the can body is called the cone. The central cylindrical structure of the can, commonly known as the main "body," is called the can body. Therefore, a standard aerosol can can be divided into: · Body · Cone · Dome

Generally speaking, commercially available tinplate aerosol cans can withstand an internal pressure of about 12-18 bar, while the typical pressure at room temperature is usually 8-10 bar. This means that under normal conditions, the pressure of an aerosol can is usually lower than its tolerance limit, with a certain safety margin.

In Europe, the use of aerosol tin cans is strictly controlled, but not completely banned. In the United States, the use of aerosol tin cans is also not completely banned, but the U.S. Environmental Protection Agency (EPA) strictly regulates aerosol tin cans products containing greenhouse gases.

Products suitable for tinplate aerosol cans: 1. Cleaning products 2. Cosmetics and personal care products 3. Industrial and home maintenance products 4. Pesticides and deodorants Substances that cannot be contained in tinplate aerosol cans: 1. Highly corrosive acidic and alkaline substances 2. Gases with particularly high pressures 3. Strong oxidants or highly volatile substances

Aerosol cans are high-pressure, sealed containers filled with compressed or liquefied gas. Because of the high internal pressure, once the can is damaged or encounters extreme temperatures, it is easy to cause an explosion hazard. The warning sign is intended to remind consumers that incorrect use of aerosol cans may cause serious physical and chemical hazards.

Tinplate sheet is a metal sheet with a layer of tin plated on low-carbon steel. In the manufacture of aerosol can, tinplate sheet has become an important material choice due to its good corrosion resistance, physical strength and machinability.

Metals, especially iron, easily react with moisture and oxygen in the air and certain ingredients in the product, causing rust or corrosion. Coatings effectively prevent moisture and oxygen from eroding the metal surface by providing a protective barrier, thereby extending the service life of the can.
