Everyone knows about membrane structure buildings, because it has become very common in our daily life. The most commonly used membrane materials in membrane structure buildings are PTFE membrane materials and PVC membrane materials. SIGMA Group will give you a brief introduction to PTFE membrane materials.

PTFE membrane material refers to a composite material formed by coating PTFE (poly tetra fluoro ethylene) resin on a base cloth woven with very fine glass fibers. Its characteristics are: high strength, good durability, fire retardant, self-cleaning It has good performance and is not affected by ultraviolet light, and the service life is more than 20 years;

It has high light transmittance, the light transmittance is more than 11%, and the light passing through the film material is natural diffuse light, will not produce shadows, and will not cause glare; the reflectivity of solar energy is 73%, so it absorbs heat Even in the case of summer sun exposure, the interior of the building will not be affected too much.

　　 The light transmittance of PTFE is one of the most widely recognized characteristics of modern membrane structures. The light transmittance of the membrane material can provide the required illuminance for the building, which is very important for building energy saving. It is especially important for commercial buildings that require a lot of light and high brightness.

Through the comprehensive utilization of natural lighting and artificial lighting, the light transmittance of the membrane material can provide a larger space for aesthetic creation for architectural design. At night, the light transmittance turns the membrane structure into a sculpture of light.

These advantages of PTFE membrane materials should reflect its beauty in membrane structure buildings. It is precisely because of the invention of this epoch-making membrane material that membrane structure buildings have evolved from tents or temporary buildings imagined by people. Modern permanent building.
