Borouge HDPE HE3490-LS is a black, bimodal, high density polyethylene classified as a MRS 10.0 material (PE100) produced by the advanced Borstar technology. Well dispersed carbon black gives outstanding UV resistance. Long term stability is ensured by an optimised stabilisation system.

Applications of Borouge HE3490-LS

HE3490-LS PE100 is recommended for pressure pipe systems in the applications field of drinking water and natural gas, pressure sewerage, relining, sea outfall and industrial. It is especially designed for the production of larger diameter, thick wall pipe, but can be processed for the whole range of diameters. HDPE HE3490 also shows excellent resistance to rapid crack propagation and slow crack growth.

Storage and Handling

  • Borstar HE3490 should be stored in dry conditions at temperatures below 50°C and protected from UV-light.
  • Improper storage can initiate degradation, which results in odour generation and can have negative effects on the physical properties of the product.
