PVC color film is cheaper than PTFE film in material and processing, and has the advantages of soft material and easy construction. However, it is inferior to PTFE membranes in terms of strength, durability, and fire resistance. PVC color film material is made of polyester fiber fabric with PVC coating. Generally, the film material used in construction is coated with a few micron thick acrylic resin on the surface treatment of the PVC coating material. To improve anti-fouling properties.

PVC color film is a special structure system different from traditional structure. The film material is not only a structural bearing member, but also a roof enclosure material. At the same time, the film material itself is a very good decorative material. Therefore, compared with the traditional structure, the film structure Has the following advantages:
1. Department of Art. The membrane structure is based on modeling and chromatics, which can combine natural conditions and national customs to create curves and shapes that are difficult to achieve in traditional buildings based on the architect's creativity. The changeable support structure and flexible membrane materials make the building shape more diversified, novel and beautiful, and at the same time reflect the beauty of the structure, and the color is rich, which can create a more free architectural shape and express a richer architectural language.
2. Energy saving. The film has high reflectivity and low light absorption, and low thermal conductivity, which greatly prevents solar energy from entering the room. In addition, because the film itself has a good light transmittance (10%-20%), the translucency of the film ensures proper natural slow-scattered light to illuminate the room. The building space can get natural scattered sunlight during the day, which can save a lot of energy for lighting.
3. Self-cleaning. The protective coating applied on the surface of the membrane material, such as PVDF (polyvinylidene fluoride), has specific characteristics of high temperature resistance and is not sticky, so that the dust falling on the membrane material surface can be washed by rain to achieve self-cleaning effect .
