The GM 5340 PRK is a High Density Polyethylene compounding specially developed for the manufacturing of pipes, underground conduits, steel pipe coating, and insulation for wires and cables. This resin is produced with bimodal technology, it has excellent mechanical properties, besides excellent resistance to stress cracking. GM 5340 PRK contains carbon black pigment that guarantees resistance against photodegradation. The amount and the type of carbon black used guarantee a high UV absorption coefficient. It contains especial additive package against copper catalytic oxidation.

Application:
Jacketing for wires and optic fiber metallic cables; insulation of copper wires and cables; self-propelled irrigation pipes; localized irrigation pipes; ducts for mining.

Process:
Extrusion.
