c) Carbon Black Geotextiles
Prime quality, non-woven, needlepunched geotextile in virgin polypropylene containing 1% carbon black UV inhibitor.
Nonwoven needle punched geotextiles are manufactured from high performance staple polypropylene fiber. In addition to the inherent chemical and biological resistance associated with polypropylene, the polymer contains 1% carbon black to protect the long-chain molecules from degradation by ultra-violet light.
