PVC membrane Vs PTFE membrane
Main performance PVC polyester fiber (PVC-PES) PTFE Membrane-fiberglass
Service life 5-15 years >25 years
Note:
PVC membrane material has different service life under different surface treatment.
Acrylic surface has 5 years’ service life generally.
Splicing PVDF surface has 7 years’ service life generally.
Non splicing PVDF surface has 15 years’ service life generally.5-15 years 		Note: PTFE membrane material base cloth is glass based and the coating is “plastic king” PTFE with a stable performance. There is not aging after longer than 30 years’ use.
Tensility

<15%-20%

Note: polyester fiber (terylene), easy to elongate

<3%-12%

Note: the fiberglass is not easy to be elongated.

Translucent rate (sunlight) 8%-25% 5%-15%
Basic color White White
Chemical stability Low
Note: PVC chemical stability is poor		 High
PTFE has a high chemical stability and can be with all strong acid, including aqua fortis, strong oxidant, reducer and all organic solvents, except melted alkali metals, fluorin mediums and sodium hydroxide higher than 300℃.
Tear resistance Very strong Strong
UV resistance Common
Note: PVC is broken and aging under ultraviolet radiation<		 Very strong

Note: PTFE has a fine weather and radiation resistance performance and a low penetrability.

Anti corrosion Common Very strong
Flexibility Soft Not soft
Folding performance Yes
Note: polyester fiber (terylene) is foldable 		No
Note: the fiberglass can be broken.
Self cleaning Common

Very good
Note: acrylic membrane material is easy to stick dust and non weldable PVDF surface PVC membrane material has the best self cleaning.
Generally, PVC membrane surface has a poorer and poorer self cleaning and the membrane material is dirtier and dirtier. 		Note: PTFE (Polytetrafluoroetylene, used for “non sticky pan”) has distinguishable non stickiness and sticks nothing. The known solid material can’t be stuck on its surface. It’ s the minimum surface energy solid material
Fireproof Grade B Grade A
Processing/installation

Easy

Note: PVC membrane material can be folded and packed randomly.

Special method

Note: PTFE membrane materials can’t be folded or packed during processing and should be roll pack and so on.

Splicing method High frequent splicing High temperature welding
Applicable temperature -30℃—+70℃ -80℃—+250℃
Toxicity Poison gas is available after burning Poison gas is available after burning
Material cost Low Higher
Secondary tension Yes No
Note:
polyester fiber is to be longer under other loads, such as wind, rain and snow, and the membrane structure is loosened and the secondary tension should be done. 		Note:
the fiberglass is not to be longer under other loads, such as wind, rain and snow, and the membrane structure is stable.
