METALEN PE-1 is a bimodal-type black high-density polyethylene manufactured from a blend of linear polyethylene and high-density polyethylene by reactive extrusion with nano-activation by organo-modified montmorillonite on modern equipment, in cutting-edge process by METACLAY CJSC. METALEN PE-1 has high strength, heating stability, high cracking resistance and unique flexibility at low negative temperatures. The material for special conditions may contain nano-UV-stabilizer. METALEN PE-1 meets the requirements of STO Gazprom 2-2.3-130-2007 and was qualified by Gazprom VNIIGAZ LLC (Conclusion No. 313239949-113-2011) for the insulation of steel pipes of any execution class with the temperature of up to +80°C”.

Technological properties

Application areas

METALEN PE-1 is recommended for the top coat of pipe insulation by side or circular (longitudinal) extrusion.

Processing methods

METALEN PE-1 is recommended to be processes on extruders with a flat or circular die. METALEN PE-1 ensures good processability in wide temperature range.The below conditions may be used when starting the extruder: Barrel: 190–230°C, Head: 190–230°C, Die: 220–225°C, Melt temperature: 220–225°C. Definitive processing recommendations may only be given when the specific material application and the equipment type used are known.
