Heilbronn / Germany, December 2022 –  BRUGGOLEN® TP-H2217 belongs to a new class of electrically neutral thermostabilisers from Brüggemann. Specially developed for reinforced and unreinforced aliphatic polyamides with metal- and halogen-free flame retardancy requirements, it ideally meets the needs of electrical and electronic applications, including those of e-mobility. Despite its high efficiency it neither has a corrosive effect on metallic components such as overmoulded sensors, nor does it influence the electrical properties of the polymer it is protecting in any significant way. 

The high efficiency of long-term stabilisation is demonstrated by the example of a PA6.6-GF30. After 8,000 h of heat storage at 170°C, the tensile strength values are still over 50%. 

A key requirement of any additives used in e-mobility applications is that the flame retardancy properties of those applications are not harmed. BRUGGOLEN® TP-H2217 is neutral in this respect as is Brüggemann’s new flow enhancer, BRUGGOLEN® TP-P2201, which is used to process glass-fibre reinforced polyamides into thin-walled and complex components with long flow paths.

Dr Kristina Frädrich, Product Manager at Brüggemann, comments: "With BRUGGOLEN® TP-H2217, compounders can for the first time produce polyamide materials that combine a UL94 V-0 classification, electrical neutrality as well as permanent heat resistance at elevated temperatures, and are thus specially tailored to the increased requirements of e-mobility. With this combination, which neither phenol- nor amine-based grades can offer, Brüggemann raises the bar for thermo-stabilisers by a considerable margin."

BRUGGOLEN® TP-H2217 is available as an easy-to-process masterbatch in granular form, with a level of 3% proving sufficient for many applications in laboratory trials.
