Product Description
Ethylene, commonly known as ETFE, is an outstanding plastic. It features excellent mechanical properties, enabling it to withstand various mechanical stresses. Its weather resistance is remarkable, allowing it to maintain stable performance under long - term exposure to harsh environmental conditions such as sunlight, wind, and rain. The material is flame - retardant, providing a high level of fire safety. With good gas barrier properties, it can effectively prevent the permeation of gases. Moreover, its chemical resistance empowers it to resist the corrosion of many different chemicals.
In addition to sharing some common properties with other resins, ETFE has unique advantages. It shows good radiation resistance, making it suitable for applications in environments with radiation exposure. It has strong adhesion to metal surfaces, facilitating its combination with metal components in various products. Compared to other fluorinated materials, it is lighter in weight, which is beneficial for applications where weight is a concern.
ETFE can be produced in two forms: powder and pellet. The powder form can be processed through electrostatic powder coating, while the pellet form can be processed by rotomolding, extrusion molding, injection molding, etc. These processing methods make it possible to produce a wide variety of products with different shapes and functions.

Application Scope
ETFE has extensive applications in numerous industries. In the chemical industry, it can be used to make chemical - resistant equipment and components due to its excellent chemical resistance. In agriculture, it can be applied in greenhouse films and irrigation systems because of its durability and resistance to environmental factors.
In the field of architecture, ETFE is widely used. For example, it is used to make building facades and skylights. The famous "Water Cube" in Beijing's National Aquatics Center has an ETFE - membrane structure exterior. The material not only gives the building an aesthetically pleasing and transparent appearance but also allows sufficient light to pass through. At the same time, it can bear certain external forces.
In the electronics industry, ETFE is used for cable insulation, electronic component packaging, and the production of parts for electronic equipment. Its good electrical insulation properties ensure the stable operation of electronic products. In the automotive industry, it can be used in various parts such as fuel lines and gaskets, thanks to its chemical resistance and durability.
In the aerospace, and nuclear industries, ETFE also plays an important role. It can be used for equipment protection and special - purpose components. In aerospace, its light weight, radiation resistance, and other properties make it suitable for spacecraft parts. In the nuclear industry, its resistance to radiation and chemical corrosion enables it to be used in relevant facilities and equipment.
