Description

METALEN PE-21 represents the nanocomposite material created using Monamet 1O4 nano-size active filler (in accordance with TU 2164-017-63341682-2014) introduced in a compound based on high-density polyethylene and a set of modifying additives. METALEN PE-21 compound contains a set of stabilizers of prolonged effect, ensuring long-term oxidative degradation resistance at increase operating temperatures. METALEN PE-21 meets the requirements for class 2-5 polyethylene compounds per STO Gazprom, 2-2.3-13-2007 “Technical requirements for factory-applied outer anti-corrosion polyethylene pipe coatings for construction, reconstruction, and overhaul of underground and offshore gas pipelines with the operating temperature of up to +80°C”.
