This premium open-cell foam strip, made of NBR+PVC foam material and featuring non-adhesive properties, is soft and non-toxic, boasting excellent weather resistance, superior flame retardancy, high/low temperature resistance, good thermal insulation, and sound absorption capabilities, with a wide operating temperature range from -40℃ to 90℃. Designed for ease of use, it can be placed on top of the air conditioner and lower window to compress and seal for optimal insulation, providing all-season protection to maintain climate-controlled air inside, sealing out drafts and dust, and reducing external noise and vibration. The foam strip, which comes in a size of 2 inches wide, 1 inch high, and 6.5 feet long, is adjustable and flexible, allowing for easy customization and cutting to size with scissors or a blade, and can be bent to conform to any shape. Additionally, it exhibits excellent resistance to compression and deformation, with strong elasticity and durability, enabling the air conditioning foam to quickly return to its original shape after compression, providing good buffering or cushioning performance and long-term shock protection for your equipment. We are proud of our weather stripping foam strip for air conditioners and confident that you will love its quality and convenience. If you encounter any issues, we promise a timely response and solution.
