Polypropylene filler yarn is a type of synthetic fiber that can be used as a filler in various applications. It is lightweight, strong, and resistant to moisture and chemicals, making it ideal for use in many different industries.
Semi-conductive filler rope, on the other hand, is a type of rope that is specifically designed for use in high-voltage applications. It is made from materials that have a low resistance to electricity, which helps to prevent the buildup of static electricity and other forms of electrical interference. This type of rope is often used in power cables and other electrical installations to help maintain the integrity of the electrical signal and prevent signal degradation.
