Covering all the Bases in Polyethylene Pipe

If you're looking for pipe grade materials that consistently outperform industry standards, you've come to the right place. The family of CONTINUUM™ Bimodal Polyethylene Resins includes:

  • High density polyethylene (HDPE) resins that meet or exceed ASTM PE4710 requirements
  • A medium density polyethylene (MDPE) resin that meets or exceeds ASTM PE2708 requirements
  • North American product offerings that meet or exceed ISO PE100 requirements

Using UNIPOL™ II Process Technology – a proprietary dual reactor, gas phase process – Dow is able to combine state-of-the-art, staged reactor technology with strong material science to produce engineered polyethylene with advanced molecular architecture. As a result, CONTINUUM Resins are able to offer a long list of advantages, including:

  • Long service life expectancy and lower total life cycle cost
  • Broad service conditions – Including high temperature/pressure performance
  • Outstanding slow crack growth (SCG) resistance – CONTINUUM™ DGDA-2420 Bimodal MDPE Resin achieves more than 150 times the minimum ASTM D2513 requirement1
  • Excellent rapid crack propagation (RCP) resistance at critical cold temperatures – CONTINUUM™ DGDA-2490 and CONTINUUM™ DGDC-2480 Bimodal HDPE Resins are at least three times more resistant to RCP than the most demanding requirements for ISO PE100 standards1
  • Potential for downgauging and/or increased throughput
  • Extrusion into a wide range of diameters, including large diameters above 14 inches
  • Installation efficiencies – Strong fusion to MDPE, HDPE, PE4710, PE80, and PE100 grades with trenchless rehabilitation capability

CONTINUUM™ Bimodal Polyethylene Resins are suited for pipe applications such as natural gas distribution, potable water distribution, industrial and chemical processing, and mining (slurry and leachates).
