Perfomance-enhancing additives for PA

Brüggemann‘s additives give polyamide compounders and processors the possibility to produce materials that exceed previous performance limits Picture: Brüggemann

At K 2019, Brüggemann presents its latest developments in performance-enhancing additives for both virgin polyamides and polyamide recyclates. The product variants range from efficiency-increasing flow enhancers for shorter cycle times and thinner wall thicknesses, through heat stabilisers for medium to very high temperatures, to reactive additives for the production of recyclates which match the quality of virgin materials.

Bruggolen TP-P1810 for example allows 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 injection molders can thus significantly widen the processing window and combine high cost efficiency with application-specific optimisation. For example, it is possible with Bruggolen TP-P1810 to reliably produce and easily process compounds with very high fiber contents (e.g. 60 %). Producers and processors of the corresponding 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 low wall thicknesses.

With the heat stabiliser Bruggolen TP-H1805, Brüggemann offers the opportunity to stabilise 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 compounders to tailor-make products for applications in borderline areas that were until now the preserve of polyphthalamides or other high-performance polymers such as PPS. Injection-molded parts produced with this additive – for example air ducts and pipes in the engine compartment – offer excellent heat resistance over the entire required temperature range. Separate activation is not needed.
