ETFE and PTFE are two commonly used fluoroplastics, and there are obvious differences in their chemical properties, physical properties, and application fields.
First of all, ETFE is a transparent polymer with good chemical resistance and is able to resist most acids, alkalis, salts and other chemicals. In addition, ETFE also has good electrical insulation properties and a low coefficient of friction, so it is widely used in electronics, chemical industry, aerospace and other fields. ETFE membrane structures are often used in the construction of ceilings and curtain walls for large buildings and facilities because they are lightweight, transparent, durable, and easy to maintain.
In contrast, PTFE is a white polymer with excellent resistance to high temperatures and chemicals, and can maintain good performance at high temperatures and pressures. In addition, PTFE also has good electrical insulation properties and a small coefficient of thermal expansion, so it has been widely used in petrochemical, electric power, pharmaceutical and aerospace fields. PTFE membrane structures are commonly used to construct high-strength, high-durability, and high-sealing equipment, such as storage tanks and pipelines.
In summary, there are obvious differences between the structure of ETFE membrane and the structure of PTFE membrane in terms of chemical properties, physical properties and application fields. ETFE membrane structure is lightweight, transparent, durable and easy to maintain, and is suitable for use in areas such as ceilings and curtain walls of large buildings and facilitiesOn the other hand, the PTFE membrane structure has the characteristics of high strength, high durability and high sealing, and is suitable for the construction of equipment with high strength, high durability and high sealing.
