ETFE Cushion ---New Technology of Membrane Structure
Basic Mechanical Property
1)Thickness and quality
Usually, the thickness is 0.05~0.25mm.
2)Tensile strength
More than 40MPa
3)Breaking elongation
The breaking elongation is up to 300%.
1)Durability: more than 25 years with good aging resistance.
2)Color and light transmission
The ETFE membrane is usually colorless & transparent, or made in white color.
3)Fire-proof
ETFE is a material of anti-flaming.
Even in the flame, ETFE membrane will only be melt and shrink but without falling drops.
ETFE membrane is very light, it has low danger when there is fire risk.
4)Self-cleaning
The surface of ETFE is very glossy with good performance of self-cleaning.
Dust and dirty covered ETFE membrane will be washed off by rain.
5)Adaptability of climate
Range of working temperature of ETFE membrane is -200~150℃.
Melting point is around 275℃. It’s of good stability and adaptability of climate.
6)Recyclable: ETFE membrane can be melted into particle and re-processed.
