PET polyester air duct film is a specialized material used for air ducts, especially in heating, ventilation, and air conditioning (HVAC) systems.
Material: PET is a thermoplastic polymer that is strong, lightweight, and resistant to moisture and chemicals.
Thickness: Film thickness varies, typically between 0.05 and 0.2 mm, depending on the specific application requirements.
Transparency: PET film is typically transparent or translucent, allowing for visual inspection of the duct interior.
HVAC systems, building construction, industrial applications requiring air ducting.
