Material Characteristics Analysis of Ptfe Membrane, Pvc Membrane, Etfe Membrane

Features of PTFE membrane material:

1. High strength, good durability, fire resistance, non-flammable, good self-cleaning and not affected by ultraviolet light, its service life is more than 20 years. 2. It has high light transmittance, and the light passing through the film material is natural diffuse light, which will not produce shadows or glare. 3. The reflectivity of solar energy is high, so the heat absorption is small.

Characteristics of ETFE film material:

The Chinese name of ETFE is an ethylene-tetrafluoroethylene copolymer, a material with high abrasion resistance, abrasion resistance, high-temperature resistance, corrosion resistance and high insulation. Ultra-lightweight: thin and light film. Superior earthquake resistance and convenient construction. Good durability: Climate adaptation: -200 ~ 150 degrees Celsius, severe weather for more than 15 years.

Characteristics of PVC film material:

Compared with PTFE, the strength and fire resistance of PVC film materials have a certain gap. The service life of PVC film materials is generally 7 to 15 years. In order to solve the self-cleaning problem of PVC film material, PVDF (polyvinylidene fluoride resin) is usually coated on the PVC coating, which is called PVDF membrane material.

Product performance

1.High mechanical strength

With a thickness of only 0.80mm, the tensile strength of the PTFE membrane has reached the level of steel. The elastic modulus of the membrane is much lower than other building materials, which is conducive to the formation of complex curved shapes of the membrane. PTFE architectural film has excellent optical properties. PTFE architectural film has excellent optical properties.

Can filter out most of the ultraviolet rays to prevent indoor objects from fading. Its transmissivity to natural light can reach 25%, and the light passing through the film is naturally diffuse, which will not produce shadows or glare, which ensures its good colour rendering. At night, it is illuminated internally and externally. Under the common illumination, the film structure forms a crystal clear translucent body, which has a strong visual impact.

2.Excellent acoustic performance

The general membrane structure has superior acoustic performance, which is almost transparent to low frequencies below 60Hz. For structures with special sound absorption requirements, a membrane structure with a FABRASRB device can be used. This combination has a stronger sound absorption effect than glass.

3.Excellent fire performance

The architectural film widely used in modern society has reached or surpassed the fire protection standards of France, Germany, the United States, Japan and China, etc., which can well meet the fire protection requirements, and has excellent flame retardancy and high-temperature resistance.

4, with good insulation performance

The single-layer film has the same thermal insulation performance as brick walls and is better than glass. Like buildings made of other materials, the interior temperature of membrane structures can be adjusted in a variety of ways.

5.Unique self-cleaning performance

With PVDF's unmatched high self-cleaning properties, fluororesin has non-adhesiveness, water-resistance and other functions. The dust and atmospheric dirt accumulated on the exterior are washed away by rain and kept clean and white for long.
