The film material is the main material of the inflatable film structure, which plays the role of sealing and bearing, which determines the use and safety performance of the inflatable film structure. It has good performance, mainly:
1. PVC
PVC stands for polyvinyl chloride film, made of polyester fabric and PVC coating (polyvinyl chloride).
The membrane material used for construction is coated with acrylic resin on the surface treatment of the PVC coating material to improve the anti-fouling performance. The price is moderate, and it is a commonly used film material for gas film venues.
2. PTFE
PTFE chemical name polytetrafluoroethylene, is a chemical inert material, is based on glass fiber as a substrate to form PTFE film. PTFE also has excellent durability, easy cleaning and stability.
PTFE film is the biggest feature of high strength, medium strength PTFE film thickness is only 0.8mm, but its tensile strength has reached the level of steel; Moreover, the elastic modulus is low, which is conducive to the formation of complex curved surface modeling. Wide temperature range, can be used in the temperature range of -70℃ ~ 230℃.
3. ETFE
ETFE bubble film, also known as ETFE air pillow film, is an alternative material of superior quality in transparent building structures.
Different requirements for reducing the transmission of ultraviolet light, preventing condensation, pattern design (coloring, pasting patterns), and giving light blocking performance can also be solved by adding additives, coating surface improvers and printing.
