New flow enhancer for semi-aromatic polyamides
BRUGGOLEN TP-P1810 from Brüggemann is the first flow enhancer for semi-aromatic polyamides which is available on the market. This product joins BRUGGOLEN TP-P1507, which is already used worldwide for aliphatic polyamides such as PA6, PA6.6 and PA12. As a result, the company now offers flow enhancers for the entire polyamide spectrum. Both demonstrate very significant improvement in melt flow while retaining the mechanical properties of finished components. Supplied in pellet form, they are easy to dose and disperse during direct injection molding and compounding.
Trials carried out with RJG Technologies, a well-known independent testing laboratory, clearly revealed that BRUGGOLEN TP-P1810 enabled in excess of 20% cycle time reduction during molding and, significantly, allowed filled compounds containing 50% and more of glass fiber to be injection molded into very intricate and complex shapes. For instance, during molding tests, the flow spiral of a semi-aromatic polyamide reinforced with 50 wt.% glass fiber was lengthened by 70% at a dosing rate of BRUGGOLEN TP-P1810 of only 1.5%. Much-improved color and appearance of the resultant molded parts are a welcome result of the excellent processing enabled by it. Alternatively, by allowing a 30°C reduction in melt temperature, the additives clear the way to gentler processing and reduced energy consumption.
Dr. Klaus Bergmann, Head of Polymer Additives at Brüggemann: “With the continually tightening emissions regulations we are seeing the pursuit for ever lighter components. BRUGGOLEN TP-P1810 and BRUGGOLEN TP-P1507 are key tools to help our customers make this happen.”
