ETFE RTP 3281Use performance

ETFE The Chinese called ethylene - tetrafluoroethylene copolymer. ETFE membrane generally has a thickness of less than 0.20mm, is a transparent membrane.
Ethylene - tetrafluoroethylene copolymer film as a crystalline polymer having a melting point of 256 to 280 ° C. Ene can be self-extinguishing when burned. High mechanical strength and resistance to shear resistance, low temperature impact properties of the existing fluorine plastic is preferably from room temperature to -80 ℃ are able to have a higher impact strength, stable chemical properties, electrical insulating properties and good resistance to radiation performance . Actual use of ETFE film began in the 1990s, mainly as agricultural greenhouse covering material, various shaped buildings the canopy membrane materials, such as playground stands, building conical roof, casino, canopy cover revolving restaurant, entertainment hall canopy cover, parking, galleries and museums. "Eighth wonders of the world," the reputation of the British new millennium should be typical engineering one of the "Garden of Eden". Connected by four dome-shaped building consisting of the world's largest greenhouse, covered with a transparent cover made of ETFE film material, its quality is only 1% of the same area of ​​glass the transparent foil can be recycled, and has good insulation sex.
ETFE film is transparent building structure superior quality alternative material for its many advantages over the years in many engineering proved to be a reliable and economical roofing materials. The membrane is made of a fluoro-polymer (ETFE) of the artificial high intensity, its unique anti-sticking surface, it has the characteristics of high stain-resistant, easy to clean. Usually the rain to clear the main dirt.
The ETFE membrane service life of at least 25-35 years, removable roof structure ideal material for permanent multi-storey. The membrane material used for the span of two or three meters inflatable support structure, geometry and climate conditions of the special projects, increasing the membrane span. Film easy to install as a standard length, typically 15-30 meters. Small span of a single layer structure may also be used a smaller size.
ETFE film reaches B1, DIN4102 fire rating standards, not drip when burned. Very light, and the quality of the film of only 0.15-0.35 kilograms per square meter. Such characteristics make it even in the smoke, also has a considerable advantage in the case of the fire caused by the film melted.
ETFE film transmittance up to 95% according to the position and surface printing. The material does not block ultraviolet light transmission inside the building to ensure natural light. By surface printing, the semi-transparency of the material can be further reduced to 50%. According to the geometric conditions and the number of layers of the membrane, the K value of up 2.0W/m2K. Cost index to a three-layer printed film, for example up to 0.77.
Because of its excellent quality, ETFE film is almost no routine maintenance. Its due to mechanical damage to the roof of a simple check (once a year is appropriate), and in accordance with the need to place maintenance. Also check the ventilation system, replace the filter device.
ETFE film may be entirely recycled materials, the production of new membrane materials can be used again, or after the separation of impurities to produce other ETFE product.
National Olympic Aquatic Centre Water Cube is made of ETFE film.
ETFE (F-40) fluorine plastic from DuPont and Japan's Asahi Glass Company, mainly used in anti-corrosion lining. Polytetrafluoroethylene corrosion resistance properties of the material, while another unique strong adhesion properties on the metal, to overcome the polytetrafluoroethylene defects not bonded to the metal, coupled with its average linear expansion coefficient close to the carbon steel line expansion coefficient, ETFE (F-40) become and the ideal metal composite material, having a very good resistance to negative characteristics.
