High-strength flame-retardant bubble aluminum foil is a composite material with flame-retardant and heat-insulating capabilities. It usually consists of three layers: the outer layer is aluminum foil, the middle layer is bubble layer, and the inner layer is flame retardant coating.

High-strength flame retardant bubble aluminum foil usually consists of three layers. The outer layer is a layer of aluminum foil, which has good corrosion resistance and flame retardant properties. Aluminum foil has excellent thermal conductivity and can reflect and radiate heat. In the middle is the bubble layer, which consists of polyethylene (PE) bubbles that form a closed-cell structure. The bubble layer provides thermal insulation and reduces heat transfer. The inner layer is a flame retardant coating, which gives the material its flame retardant properties.

The insulating properties of high-strength, flame-retardant bubble aluminum foil come primarily from the bubble layer. The gases in the bubble layer block the conduction of heat, thus reducing heat transfer. In addition, the outer layer of the aluminum foil has radiant reflective properties that reflect heat back to the source, further improving the insulation effect. This makes high-strength, flame-retardant bubble aluminum foil very popular for thermal and insulation applications.


The flame-retardant properties of high-strength, flame-retardant bubble aluminum foil are primarily due to the flame-retardant coating on the inner layer. The flame-retardant coating inhibits the spread of flame and slows down the development of fire, thus providing a higher level of safety. This has led to the material being used in a wide range of applications where fire resistance is required, such as fire separation in buildings and fire barriers for electrical equipment.

High-strength flame retardant bubble aluminum foil is relatively lightweight and flexible. It can be easily cut and installed to fit surfaces of different shapes and sizes. This makes it more flexible during construction and allows it to meet a variety of special requirements. The outer layer of aluminum foil has good corrosion resistance against oxidation, humidity and chemicals. This gives high-strength flame-retardant bubble aluminum foil a longer service life in harsh environments.

High-strength, flame-retardant bubble aluminum foil is used in a wide range of applications. In construction, it is used as insulation for roofs, walls and floors, improving indoor temperature control and energy efficiency. In the automotive industry, it is used in vehicle insulation liners to reduce heat transfer from engines and exhaust systems. In the aerospace industry, it is used in aircraft insulation to provide a comfortable ride and energy savings. In addition, high-strength flame-retardant bubble aluminum foil can be used in applications such as heat sinks, shielding materials and electromagnetic interference shielding for electronic equipment.
