Aluminum-plastic composite tape is a type of tape used for cable wrapping and shielding. It is made by combining a layer of aluminum foil with a layer of plastic film, typically made from materials such as polypropylene or polyester. This tape is flame retardant and highly resistant to high temperatures, making it suitable for use in demanding environments. The filler rope made from the same material is used for water-blocking purposes to prevent moisture penetration in the cable.
