LUCOBIT RESINS AND THEIR USE
IN COMPOUNDING APPLICATIONS
Compounding of plastics is the most important upstream technology used in the industry. It is estimated that of the 200+ million tons of plastics consumed globally roughly 65+ % are compounded to render the initial polymer suitable for down-stream processing into valuable products. This process step also includes the inclusion of many different and targeted additives so that e.g. expected color schemes, light stabilization, anti-ageing properties etc. can be met. Here, the realm of masterbatch production begins with many of its specialized and important intermediates.
A very significant market to be mentioned here specifically is the ‘Cable & Wire’ application. Today, especially thermoplastic materials are used replacing the more rubbery, elastomeric materials from the past. Polyethylene (PE) and polyvinylchloride (PVC) are the most abundant polymers used in and for this application – pure, compounded or even as part of a masterbatch. While PE exhibits excellent insulation properties, chemical resistance, flexibility and little weight PVC shows somewhat reduced performance in some of these metrics but superior in others.
LUCOBIT AG’s Lucofin® products give you the best of both worlds: our thermoplastic copolymer based on ethylene and butylacrylate (EBA) depicts incredible versatility ranging from flexibility, high temperature stability, chemical resistance etc. to name only a few.
Lucofin® 1400MN and Lucofin® 1492M HG are used successfully in wood-plastic-composite materials (WPC Compounds). Aside from the already known range of applications in the construction industry e.g. for decking-profiles, other areas of application are becoming more prominent such as injection molding. Lucofin® 1492M HG as adhesive or coupling agent/layer, possibly in combination with Lucofin® 1400HN/MN/PN as polymer modifiers, can improve the handling and the mechanical properties as well as the long-term behavior of the resulting blends in a much more sustainable way.
A reduced water absorption as well as a reduced moisture expan-sion after water absorption (after conditioning as well as under dry conditions) result in significantly improved long-term prop-erties when used outside or while exposed periodically to rain and UV radiation (sunlight).
