Bruggolen TP-H2062 is a new metal and halide-free heat stabiliser for polyamides from L. Brüggemann GmbH, offering sustained protection in a temperature range of 120-170°C. Providing electrically neutral stabilisation, it prevents contact corrosion whilst maintaining the mechanical properties of the compounds even after long-term ageing.

Avoiding contact corrosion: New metal and halogen free heat stabiliser for PA in E&E applications
Brüggemann’s newly developed Bruggolen® TP-H2062 is a very powerful metal and halogen free heat stabilizer which enables electrically neutral PA compounds for electrical and electronic devices at elevated temperatures.
TP-H2062 is available as a dust-free, highly dispersible masterbatch. Depending on the application, its dosage can be adjusted to meet a wide range of temperature levels and profiles.
Compounders supplying the electrical and electronics (E&E) industry have long searched for a metal and halide free heat stabilising additive to preserve the integrity of polyamide components at elevated temperatures, as well as electrical properties such as CTI, without causing electrical corrosion. Bruggolen TP-H2062 overcomes the drawbacks of both classic copper iodide and phenolic based antioxidants. The former offers a superior long-term protection for polyamides all the way up to 180°C, but contain halides that can promote electrical corrosion as a reason for component failure, being highly critical for sensitive sensors, connectors and similar applications. This is not the case for phenolic-based additive packages, but their protection capability rapidly decreases at temperatures above 120°C, losing their effectiveness beyond 150°C.
Dr Kristina Frädrich, Product Manager Polymer Additives, said: “With our new Bruggolen TP-H2062 we are now able to offer a highly efficient and cost competitive product, satisfying an urgent need of the industry. It is a powerful addition to our heat stabiliser portfolio for E&E applications.”
