Glass fiber silicone resin architectural membrane

The silicone resin has excellent resistance to high and low temperature, water repellency, oxidation resistance, etc. The film has high tensile strength and elastic modulus, and also has good light transmittance. The Vestar film developed by Owens Corning of the United States is made of this resin coated with glass fiber cloth. Today, this type of film is used in a small number of applications and there are fewer manufacturers.

Glass fiber synthetic rubber architectural membrane

Synthetic rubber (such as nitrile rubber, neoprene) has good toughness, stable to sunlight, ozone, heat aging, outstanding wear resistance, chemical resistance and flame retardancy, can achieve translucent state, but it is easy to send Yellow, so it is generally used for dark coatings. Expanded PTFE architectural membrane. A PTFE resin film is obtained by attaching a fluororesin film to both sides of a base fabric woven from expanded PTFE fibers. Because of its high cost, the general construction takes into account both cost and performance. This type of membrane is rarely used, and there are not many foreign manufacturers.

ETFE architectural membrane

Made directly from ETFE (ethylene-tetrafluoroethylene copolymer) raw meal. ETFE not only has excellent impact resistance, electrical properties, thermal stability and chemical resistance, but also high mechanical strength and good processing performance. In recent years, the application of ETFE membranes has shown strong advantages and market prospects in many aspects to replace other products. This film is particularly good in light transmission, known as "soft glass", light in weight, only 1% of the same size glass; good toughness, high tensile strength, not easy to be torn, ductility greater than 400%; weather resistance and resistance Strong chemical corrosion, melting temperature up to 200 ° C; can effectively use natural light, save energy; good acoustic performance. The self-cleaning function makes the surface less susceptible to contamination, and the rain washes away a small amount of contaminated dirt. The cleaning cycle is about 5 years. In addition, the ETFE film can be pre-formed into film bubbles in the ready-made, easy to construct and repair. ETFE also has shortcomings. If the external environment is easy to damage materials, it will cause air leakage and high maintenance costs. However, with the construction of large stadiums, tourist places, waiting halls, etc., ETFE will highlight its advantages. At present, there are very few companies producing such membranes. Only a few companies such as ASAHIGLASS (AGC), Asahi Glass, and Kewell of Germany can provide ETFE membranes. The development and application of such membranes are not only in developed countries. A few years of history.
