The added capacity is expected to come online in several phases starting in 2020 and will enable both divisions to meet growing demand for Surlyn, Nucrel, Fusabond (P&SP) and Vamac (T&AP) specialty materials used for applications in food packaging, transportation and consumer goods.
The investments will support growth of the Packaging & Specialty Plastics (P&SP) business in the Materials Science division (to be named Dow), as well as the Transportation 8< Advanced Polymers (T&AP) business of the Specialty Products division (to be named DuPont), The added capacity is expected to come online in several phases starting in 2020 and will enable both divisions to meet growing demand for Surlyn ionomers used in applications like high-end cosmetics packaging; Fusabond ethylene copolymers with anhydride functionality used as coupling agents for applications such as PE/wood composites; Nucrel acid copolymers used as tie layers; and Vamac ethylene acrylic elastomer terpolymers used in high-temperature automotive engine and transmission seals.
Introduced as Vamac VMX-5000, the new pre-compound has been designed to meet the latest challenges to automotive hoses and seals imposed by high pressure turbo charging, exhaust gas recirculation and other technologies requiring resistance to higher temperatures and aggressive fluids.
Mixing capabilities: SBR, EPDM, EVA, natural, Viton, Vamac, Hypalon, nitrile, hydrogenated nitrile, carboxylated nitrile, millable urethane

The company helps customers choose from its extensive formulation library which currently includes perfluoroelastomer (FFKM), fluoroelastomer (FKM), polyacrylate (ACM), Vamac (AEM), hydrogenated nitrile (HNBR), carboxylated nitrile (XNBR), nitrile (NBR), ethylene propylene (EPDM), epichlorohydrin (ECO), natural rubber, polyisoprene rubber (IR), styrene butadiene (SBR) and polychloroprene (CR).
This project includes the installation of a $1.1 million 3D suction blow molding machine for Hytrel and Zytel blow molding air ducts, as well as a rubber injection molding press and molds for Vamac rubber sleeve and molded air ducts.
As manufacturers continue to look for cost-effective ways of bringing lower emissions and more fuel-efficient cars to market, the company offers several solutions, including opportunities to reduce vehicle mass without compromising safety through the use of Vizilon thermoplastic composites in different structural applications; significant costs savings and performance gains through the use of Hytrel thermoplastic elastomer in jounce bumpers as a replacement for incumbent foam polyurethane; and the latest applications of the firm's portfolio of high temperature tolerant materials such as Zytel nylon resin, and Hytrel and Vamac ethylene acrylic elastomer to enable the downsizing of engines.
The investigated polymers were Zetpol 2510 (HP Zetpol HNBR from Zeon Chemicals) and Vamac GLS (DuPont).
In addition, a compound based on Vamac IP (AEM-IP) was used for comparison, and the recipe for this competitive polymer was taken from the manufacturer's literature (ref.
