...nerally requires less raw material than shrink-wrapping. Apart from that, stretch-wrapping does not require the use of hot air or an open flame as does the shrink-wrap process. The most commonly used raw materials for this application are EBA and EVA copolymers and mPE grades, generally based on the coextrusion technology. Extrusion coating with PE-LD is used predominantly in the packaging sector. The main field of application is the coating of paper (Fig. 2), board and aluminium (front picture)...

...her melt strength and crystalline melting point of the new ethylene-acrylate copolymers. The joint venture in Antwerp/Belgium produces three basic grades: ethylene-methyl acrylate (EMA), ethylene-ethyl acrylate (EEA) and ethylene-butyl acrylate (EBA). Their acrylate content ranges from 7 to 27wt.-% with melt index values between 0.4 and 9.0g/10min (Fig.2). High Thermal Stability and Melting Point All new ethylene-acrylate copolymers have a significantly higher heat resistance than EVAs and oth...

...need to be heated with hot air or an open flame. Industry insiders therefore expect that the stretch hood will gain a significant share from shrink hoods. Raw materials used for stretch hood production are predominantly EBA and EVA copolymers. Extrusion coating is still a domain of PE-LD. The main field of application is the coating of paper, cardboard and aluminium for milk and fruit juice packaging. Injection Moulded Articles, Cables and Steel Tube Coating Injection moulded articles make up ...

...ed (intumescent system). A more recent development in this field (trade name: Casico; manufacturer: Borealis Group) exploits the synergy between special plastics and functional carbonate fillers (Fig.5). To be more specific, an EBA base polymer (ethylene/butylene/acrylate copolymer) is combined with about 30% CaCO3 and some polyolefin. A few percent of silicone elastomer are also incorporated as an additive. Under the action of heat, the EBA pyrolyses to form acrylic ester and undergoes a chemic...

...ess is additionally the only process (conducted in either an autoclave or a tubular reactor) which permits copolymerization with polar comonomers to produce ethylenevinyl acetate copolymer (EVA), ethylene-butylacrylate copolymer (EBA) and ethylenemethylacrylate copolymer (EMA). The current trend is towards tubular reactor technology, which is increasingly displacing autoclave technology, with mainly the smaller autoclave reactors being shut down. The reason for th...

...as an ideal substitute for aluminum and magnesium hydroxide, since it is less expensive and more effective than these. Named as areas of application are polyvinyl chloride (PVC), ethylene-vinyl acetate (EVA), ethylene-butylacrylate copolymer (EBA), polyethylene (PE), polypropylene (PP) and rubber for the fields of foam materials, automotive, cables and wires, building construction and furniture. The advantages claimed for Ultracarb are a 10 to 20 % price advantage over aluminum hydroxide and a h...
