Material Notes:

GM5240PR is a high-density polyethylene compound specially developed for the manufacturing of pipes, underground conduits, and steel pipe coating. This resin is produced with bimodal technology and shows excellent mechanical properties and resistance to stress cracking. GM5240PR contains carbon black pigment that protects it against ultraviolet radiation action and photodegradation. Its applications include: triple-layer coating for metallic pipes, localized irrigation pipes, and ducts for mining.
