Material Notes:

GP5550BK is a high-density polyethylene with high molar mass. It is produced with bimodal technology and shows excellent mechanical properties and high resistance to stress cracking. GP5550BK contains carbon black pigment that protects it against ultraviolet radiation action and photodegradation. Its applications include: straight pipes for mining, subducts for energy and telecom, jacketing of optic fibers and metallic cables, geomembranes, and blends for irrigation pipes.
