Introduction to coated aluminum foil

What is aluminum coated foil? Aluminum foil is a thin metal material. Aluminum foil alloy has good thermal conductivity, electrical conductivity and corrosion resistance, and has been widely used in industrial production. Coated aluminum foil is a layer or multiple layers of material coated on the surface of aluminum foil to increase its physical properties, chemical properties and appearance. In addition to improving the surface properties of aluminum foil, aluminum foil coating can also enhance its heat resistance, rust resistance, corrosion resistance and mechanical properties.

Types of aluminum foil coatings

1. Protective coating: Protective aluminum foil coating is used to enhance the anti-rust and anti-corrosion properties of aluminum foil. Common coatings include fluorocarbon coating, thermoplastic resin coating, epoxy resin coating, etc.. Par exemple, aluminum oxide coating can improve the corrosion resistance of aluminum foil and make it more durable.
2. Decorative coating: Decorative aluminum foil coating is used to improve the appearance of aluminum foil. Common coatings include multi-color coating, color paint coating, electroplating coating, etc..
3. Coating reinforcement layer: By coating a layer of reinforcement material on the surface of aluminum foil, the strength and hardness of aluminum foil can be improved, making it more wear-resistant and durable.
4. Coating toughening layer: Coating a layer of toughening material on the surface of aluminum foil can improve the toughness and tear resistance of aluminum foil and make it more durable.
5. Coating insulation layer: By coating a layer of insulation material, the insulation performance of aluminum foil can be improved, making it more suitable for applications in high temperature environments.
6. Coating barrier layer: Aluminum foil itself has good barrier properties, and by coating one or more layers of barrier materials on the surface, its barrier properties to moisture, oxygen or other harmful substances can be improved.

It can play a role in protection, reflection, conduction, etc., and improve production efficiency and product quality.

Performance characteristics of aluminum foil composite materials

Léger
Aluminum foil itself has the characteristics of light weight. The density of aluminum foil is only 2.70g/cm³. After the aluminum foil alloy is compounded with other materials, the overall weight is still relatively light, which is suitable for products that require light weight.

Résistance à la corrosion
Aluminum foil has good corrosion resistance. After being compounded with different materials, it can effectively improve the corrosion resistance of the composite material and extend the service life.

Bonne conductivité thermique
Aluminum foil has good thermal conductivity. After being compounded with other materials, it can improve the thermal conductivity of the composite material and is suitable for fields that require thermal conductivity.

Good decorative effect
The surface treatment process of aluminum foil composite materials is diverse, and products of different colors and patterns can be made, which has good decorative properties
