LANXESS develops new PBT product range with outstanding tracking resistance

Pocan E is ideal for compact electrical and electronic assemblies with a wealth of opportunities for use in electric vehicles.

Mumbai, October 4th, 2022 – Specialty chemicals company LANXESS has developed new polybutylene terephthalate (PBT) compounds for use in electrical and electronic assemblies. Under the name Pocan E, the company is now offering a product range comprising short-glass-fibre-reinforced grades that are especially suited to applications in e-mobility and the electrical/electronics (E/E) industry thanks to their tracking resistance and insulation properties.

With their tracking resistance, the new compounds score the best possible rating of 600 in the CTI A test (Comparative Tracking Index – IEC 60112) and therefore meet the requirements of the highest insulation class according to IEC 60664-1. “Previously, glass-fibre-reinforced PBT compounds with such high tracking resistance were not readily available on the market. We have now closed that gap. We have also succeeded in providing the materials with further advantages such as optimized mechanical properties as well as excellent flowability, hydrolysis resistance, and flame-retardant properties. In addition, they are highly suitable for colouring – orange, for example,” explains Dr Claudia Schmid-Daehling, who shares the responsibility for PBT product development at LANXESS. High suitability for colouring is important for various safety-relevant components such as high-voltage connectors that must be clearly colour-coded.

Highlights include:

·         Tracking-resistant even above 600 volts

·         Insulation properties scarcely dependent on humidity and heat

·         Improved flowability and impact resistance

·         Hydrolytically stable compounds

·         Halogen-free, flame-retardant properties can also be realized
