Disadvantages of etfe membrane materials
Although the tensile strength and tear strength of 1 are higher, they are far lower than those of PVC and PTFE films, so the span of the structure is smaller than that of fabric-like film structure.
2, when using inflatable, should have the corresponding mechanical equipment and electrical equipment, high maintenance costs in the process of use.
3. There are few manufacturers and the price of materials is high.
Advantages of ETFE membrane structure:
1, which has good fracture and tear resistance.
2. The strength in the longitudinal and vertical directions is relatively balanced, and the uniformity of the membrane material is good.
3. The light transmittance is high, which can reach over 95%.
4. Good self-cleaning, dustproof and weatherproof, and the interval of manual cleaning is much longer than that of PVC and PTFE films.
5, excellent anti-aging ability, service life of more than 25 years.
6, excellent chemical corrosion resistance, can be used in special environments, and can resist most acids and bases.
7. Excellent climate adaptability, which can be directly exposed to the temperature of -2000℃~+ 1500℃.
8, good impact resistance and wear resistance, suitable for outdoor environments such as flying sand and hail.
9, good flame retardancy, good insulation performance, fire rating of B 1.
10, recyclability, and the film material can be reused after hot melting.
