Extrusion International 5-2019

PREVIEW 78 Extrusion International 5/2019 At K 2019, Brüggemann will present its latest developments in performance-enhancing, cost-effective additives for both virgin polyamides and polyamide recyclates. The innovations range from efficiency-increasing flow enhancers for shorter cycle times and thinner wall thicknesses, through new heat stabilizers for medium to very high temperatures, to reactive additives for the production of recyclates which match the quality of virginmaterials. BRUGGOLEN ® TP-P1810 allows for the first time a significant improvement in flow properties of polyphthalamides (PPA, such as PA6T, PA6T/6I, PA6T/6.6 etc.) while retaining overall mechanical property characteristics. Compounders and in- jection molders can thus significantly widen the processing window and combine high cost efficiency with application- specific optimization. For example, it is possible with BRUG- GOLEN ® TP-P1810 to reliably produce and easily process compounds with very high fiber contents (e.g. 60 %). To- getherwithBRUGGOLEN ® TP-P1507 for aliphatic polyamides (such as PA6, PA6.6, PA12 etc.), which was first introduced at K 2016, Brüggemann offers flow enhancers for all poly- amide types. Producers and processors of the correspond- ing compounds will benefit from much shorter cycle times. Furthermore, both flow enhancers allow the production of large or complex parts with long flow paths and/or lowwall thicknesses. Brüggemann underlines its recognized development exper- tise and its ability to offer solutions for all stabilization tasks by bolstering its already extensive existing product range with exciting and unique antioxidants which are launched at K 2019. • Phenolic Plus BRUGGOLEN ® TP-H1803 fills the price and performance gap between existing phenolic-based and cop- per-based stabilizer blends. It improves long-term heat ag- ing stabilization compared to conventional phenolic systems, extending the temperature range to reach peaks of 180 °C, something not possible with standard phenolics. • In cases where long-term resistance at elevated tempera- tures up to 180 °C is a priority, Brüggemann offers BRUG- GOLEN ® TP-H1607, a new high-performance and cost-ef- fective copper iodide-based stabilizer. Based on proprietary technology, its effectiveness significantly exceeds that of the traditional copper iodide/potassium iodide stabilizers with- outmakingany compromises in terms ofmaterial properties. As a result, the required thermal protection is reached with very low concentrations – a particular advantage in E+E ap- plications. • With the new BRUGGOLEN ® TP-H1805, Brüggemann of- fers the opportunity to stabilize fiber-reinforced aliphatic polyamides for long-term use at temperatures up to 200 °C for PA 6 or up to 230 °C for PA 6.6. This enables compound- ers to tailor-make products for applications in borderline ar- eas that were until now the preserve of polyphthalamides or other high-performance polymers such as PPS. As an established manufacturer of high-performance addi- tives for polyamides, Brüggemann offers a broad portfolio for the recycling of these polymers. The range covers long- term heat agents, processing stabilizers, flow enhancers, reactive chain modifiers, nucleating agents and other func- tional auxiliaries. Upcycling for high-quality applications ne- cessitates the targeted selection and combination of these additives. Especially important are reactive chain modifiers that enable molecular weight and viscosity to be precisely adjusted to suit the needs of any particular application. • BRUGGOLEN ® M1251 compensates, through linear chain lengthening, any decline in molecular weight during previ- ous processing, and thus improves the mechanical proper- ties of the recyclate to match those of virgin material. BRUG- GOLEN ® M1253, available as a smaller pellet size of the same additive, makes for easier dosage during compounding. • BRUGGOLEN ® TP-M1417 specifically shortens excessively long molecular chains of high-viscosity polyamide scrap, e.g. from extrudate, fibers or cast polyamides. Only small quan- tities and a single extrusion step are sufficient to produce high-grade recyclate that is optimally suited for injection molding and with performance properties that match those of virginmaterial. These chain modifiers are particularly effective in enabling secondary PA material to meet high quality specifications and, as a result, help to meet the need for increasing recy- cling quotas. L.
