Hydrolysis Resistant PBT for Automotive E&E Applications
Hydrolysis Resistant PBT for Automotive E&E Applications
Water and humid conditions cause the polymer chains in PBT-based materials, especially at elevated temperatures, to hydrolytically splitting of chains, thus reducing the material's properties such as strength, impact resistance, electrical insulation and fire resistance. Therefore, the use of PBT materials with increased hydrolysis resistance is quite critical, especially in materials developed for electronic parts such as connectors, busbars and brackets that will be exposed to humidity at high temperatures in electric vehicles.
Tecodur® PB70 GR30 NL MS (PBT, 30% glass fiber reinforced, hydrolysis resistant) maintains its tensile strength compared to non-hydrolysis stabilized materials when tested at 85°C and 85% humidity and is suitable for safe use in harsh conditions (Graph 1)
In addition to its hydrolysis resistance, it complies with OEM specifications owing to its processing advantages, impact strength level, high CTI value and electrical insulation. It provides wide range use in critical applications with RAL 2003 orange and black color options.
