Nordel epdm molecular Catalyst Product Launch For Transportation

Midland, Mich - October 09, 2017 -

Dow Elastomers, a business unit of DowDuPont Materials Science (NYSE: DWDP) to be named Dow, introduced three new NORDEL™ EPDM (ethylene-propylene-diene terpolymer) products that enable automotive part manufacturers and brand owners to make higher performing weatherstrip parts, and meet consumer demands and market trends for lightweighting, safety and aesthetics. These products will be manufactured using first-of-its-kind advanced molecular catalyst technology at Dow’s new next generation NORDEL EPDM production unit, located in Plaquemine, Louisiana.

\"The extra fast cure (XFC) grades of NORDEL EPDM will pave the way for OEMs to create high-quality dynamic and static automotive weatherstrip products more efficiently so brand owners can meet increasing consumer and regulatory demands for lightweight, fuel-efficient cars with dampened vibrations, isolated road noise and appealing aesthetics,” said Dave Mitchell, global marketing director for Dow Elastomers.

Improving Weatherstrip Performance to Meet Market Trends

The next generation NORDEL™ EPDM facility will produce a comprehensive portfolio of NORDEL™ EPDM products, including the new extra fast cure (XFC) grades that enable manufacturers to challenge the limits of part quality and design, extrusion and injection molding throughput, and ultimate physical properties in thermoset rubber compounds.

Used in automotive sealing applications for car doors, glass and window, trunk and hood seals, new NORDEL EPDM XFC products are extremely high-quality, low gel polymers that provide the optimum balance of surface sealing and aesthetics, part strength, and improved elastic and compressive properties to enable weatherstrip that:

  • Deliver high-end surface finish by providing overall improvement in surface quality, and meet consumer demands for cars with pleasing aesthetics and long lifetime appearance
  • Meet or exceed requirements to dampen vibrations, isolate road noise and prevent wear of and contact with other metal and plastic components
  • Meet NHTSA CAFE 2022-2025 targets for fuel efficiency by reducing weight of the weatherstrip by up to 15 percent

The NORDEL EPDM XFC grades mix and cure rapidly, process faster and deliver high filler acceptance, while allowing the manufacturer the flexibility to focus on design rather than the quality or performance of the raw material.

The three new next generation NORDEL EPDM grades include:

  • NORDEL™ 6555 OE for class A manufacturing of sponge weatherstrip profiles
  • NORDEL™ 6565 XFC EPDM for class A manufacturing of dense/microdense weatherstrip profiles
  • NORDEL™ 6530 XFC for class A manufacturing of corner injection molds

Leading the Way with Advanced EPDM Technology

The new NORDEL™ EPDM XFC products will be manufactured at the next generation NORDEL production facility, a key part of Dow’s U.S. Gulf Coast investments. The facility will use Dow’s new advanced molecular catalyst technology, which exceeds capabilities of current catalyst technologies, delivering performance attributes, such as ultra-high efficiency, broad molecular weight and increased filler acceptance. The first-of-its-kind catalyst technology also delivers industry-leading sustainability benefits, when compared to traditional Ziegler Natta EPDM technology:

  • 20-25 percent reduction in overall energy use, and an almost 40% reduction in CO2 emissions1
  • On average 50 percent improvement in overall environmental impact across categories, including smog (45%) and ozone depletion (70%)1

“Dow’s advanced molecular catalyst technology and manufacturing process are leading benchmarks for production efficiency, energy efficiency and sustainable supply,” said Bob Gowell, global R&D director for Dow Elastomers. “This catalyst technology enables new innovations in polymer structures like the extra fast cure (XFC) NORDEL™ EPDM products and will ensure that we are delivering on our commitment to our customers’ growth, helping them to meet growing and evolving industry and sustainability trends.”
