ETFE Casting Film Extrusion Line

ETFE material introduction

ETFE is a member of the fluoroplastics family. It was developed in the 1970s. Its Chinese name is ethylene tetrafluoroethylene copolymer. ETFE film, commonly known as "soft glass", usually has a thickness of 0.02-0.1mm. It is widely used in various fields because of its good light transmittance, self-cleaning, insulation, moisture and heat resistance and aging resistance. ETFE fluoroplastic casting film contains fluorine, which is prone to thermal decomposition during hot processing, resulting in corrosion to processing equipment and molds. Therefore, processing equipment and process are different from ordinary thermoplastics. Using specially designed equipment and process technology, Gwell machinery has successfully developed the casting and extrusion production line of fluoroplastic films such as ETFE.

Advantages of ETFE fluorine membrane products

1. ETFE membrane is a high-quality material in transparent building structure, with a light transmittance of more than 90%. Its unique surface self-cleaning makes it highly anti fouling and easy to clean. Usually, rainwater can remove the main dirt, which is higher than that of glass.

2, ETFE film has anti-aging, corrosion resistance, long life and so on. The general service life is 25-35 years;

3. ETFE membrane has light weight, high fire rating and no dripping during combustion;

4. ETFE membrane can be recycled completely, which is environmentally recyclable and does not pollute the environment.

5. It has good low temperature resistance and is not brittle when exposed to - 200 ℃ - 150 ℃

Main uses of ETFE casting film:

     ETFE membrane material is a transparent material. As curtain wall or roof material, it is a newly developed application field in recent years. It has been applied in more than 100 projects. The thickness of membrane material in the construction field is usually less than 0.20mm. ETFE membrane is often made into air cushion in membrane building structure. The earliest ETFE project has a history of more than 20 years. Represented by the garden of Eden in the UK, ETFE film is selected as the roof material for the water cube natatorium, the main stadium of the 2008 Beijing Olympic Games. "Water Cube" is the largest membrane structure project, which is composed of 3000 air bags, with an area of 110000 square meters, and the amount of ETFE raw materials reaches 200t.

     ETFE film can be used not only for construction and agriculture, but also for automotive glass film, antifouling inner and outer packaging materials, battery diaphragm, adhesive container, conveyor belt in food industry, film for electronic components, solar cell back plate film, flexible printed circuit board, agricultural film, computer wire circuit, medical packaging film, etc

Features of ETFE fluorine film casting production line:

1. The extruder screw, barrel and runner are made of special high-temperature and strong corrosion-resistant steel to realize the stable extrusion of fluoroplastics and the long-term and stable operation of the equipment;

2. Carry out technical cooperation with domestic universities and scientific research institutions, professionally design screw structure and die structure according to the particularity of fluorine materials, and cooperate with special molding, winding and other processes to realize the rationalization, industrialization and large-scale production of fluorine plastic products;

3. The configuration design of the whole machine is practical and reasonable. It adopts special safety protection mechanism, PLC touch screen control, whole machine interlocking, simple operation and high safety.

4. The manufacturing thickness of ETFE fluorine film is generally 20 ~ 40 μ m. The film-forming width can reach 1300mm, the production line speed is 8-30m / min, and other specifications can be customized through negotiation
