Ethylene Propylene Diene Terpolymer (EPDM)

EPDM is helping drive better rubber pellets with more sustainability solutions

Ethylene Propylene Diene Terpolymer (EPDM) materials from Dow help produce more rugged yet sustainable rubbers. Designed to excel in the harshest environments, EPDM is resilient against high temperatures and abrasive chemicals, offering uncompromising durability, no matter the application.  

EPDM is a tough material, but it's easy to customize. With Dow's innovative AMC technology, our industrial EPDM products are remarkably robust and user-friendly. Our gel-free polymers also make working with EPDM cleaner and more efficient, enabling more streamlined and sustainable manufacturing solutions.

NORDEL™ EPDM products feature the widest range of ethylene content available in the industry. Available in both bale and free-flowing pellet forms, this portfolio is progressively expanding with new products tailored to meet specific customer and industry needs.

NORDEL™ EPDM

These high-quality, virtually gel-free polymers - including ultra-high-molecular-weight and oil-extended grades - are an excellent choice for a long list of automotive, construction, consumer and other applications.

Technology to tailor your advantage

Our EPDM polymer is made using proprietary, advanced molecular catalyst (AMC) technology in a solution process, which allows it to do some amazing things. AMC technology enables the tailored design of EPDM molecular architecture, including balanced processing and physical properties. Key benefits of this exclusive technology include:

  • Ultra-high molecular weight
  • Broad molecular weight distribution capability
  • High diene content
  • High to low polymer Mooney viscosity
  • Oil-extended grades
  • Wide range of ethylene content, from amorphous to semi-crystalline
  • Higher long-chain branching capability
  • Ultra-clean, low gel content
  • High productivity
  • Fast mixing and processing
  • Fast curing
  • Increased filler acceptance
  • Extrusion and injection foaming
  • Improved filler additives incorporation and dispersion
  • Scrap reduction

Performance and sustainability

Life cycle analysis of EPDM produced with AMC technology shows that it has much lower environmental impact than producing Ziegler-Natta EPDM,(1) including 20-25 percent less energy demand, overall improvement across categories, 45 percent less smog, 69 percent less impact on ozone depletion, 55 percent less eutrophication, 39 percent less CO2 emissions, and 37 percent less acidification.
