New Ethylene Acrylates Can Run Hotter.A new line of specialty ethylene copolymers from DuPont Packaging and Industrial Polymers, Wilmington, Del., reportedly offers high melt strength and heat stability for high-temperature processing as packaging resins, additive carriers, and polymer modifiers. New Elvaloy AC resins include ethylene methyl acrylate (EMA (1) (Enterprise Management Architecture) An earlier strategic plan from Digital for integrating network, system and application management. It provided the operating environment for managing a multi-vendor network. ), ethylene ethyl acrylate (EEA EEA European Economic Area EEA European Environment Agency EEA Employment Equity Act (Canada) EEA Een En Ander (Dutch) EEA Erick van Egeraat Associated Architects EEA Energy and Environmental Analysis ), and ethylene butyl acrylate (EBA EBA Eisenbahn-Bundesamt (German) EBA Euro Banking Association EBA Emergency Brake Assistance EBA Enterprise Bargaining Agreement (Australia) EBA Elite Beat Agents (video game) ) copolymers. DuPont acquired the technology for these products through a new manufacturing joint venture with Borealis of Denmark. Uses include blown and cast film, extrusion coating, lamination lamination a laminar structure or arrangement. , and film modification. The copolymers are highly compatible with LDPE LDPE abbr. low-density polyethylene and bond easily to PET, PP, and nylon. These highly polar copolymers also act as cost-effective tougheners for PP, nylon, PET, ABS, and PBT/ABS. For example, adding 10% of an acrylate copolymer to PP boosts notched Izod impact by two to three times at room temperature. The copolymers also serve as carriers for fillers and pigments. |
