Borealis BorSafe™ ME3440-W MDPE
Categories: Polymer; Thermoplastic; Polyethylene (PE); Medium Density (MDPE)

Material Notes: BorSafe ME3440-W is a bimodal polyethylene compound produced by the advanced Borstar technology. The product is a medium-density polyethylene compound in pellet form and contains a combination of stabilizers and carbon black to ensure a reliable long-term stability and UV-resistance. BorSafe ME3440-W is classified as an MRS 8.0 material (PE80).

Applications:

  • Cable protection pipes
  • Irrigation pipes
  • Drinking water
  • Relining
  • Gas distribution
  • Sheets and profiles
  • Industrial applications
BorSafe ME3440-W is recommended for pressure pipe systems in the application fields above.

Specifications: BorSafe ME3440-W is expected to meet the applicable requirements included in the below mentioned standards provided it is processed using sound material handling and processing practices as well as appropriate testing procedures. EN 12201; ISO 4427; EN 1555; ISO 4437; EN ISO 15494

BorSafe ME3440-W provides an improved performance level in terms of drinking water related requirements such as migration limits. The sensoric properties like taste & odor are regularly monitored for the compound to ensure a high constant level of quality. The material shows excellent mechanical toughness and crack resistance also at lower temperatures. Thanks to the molecular structure, it offers outstanding extrudability and good melt strength, supporting a problem-free extrusion process to tight tolerances.
