Reinforced material can protect automotive electronics

BASF has developed a new glass fiber reinforced polybutylene terephthalate (PBT) material which can used to make small components in automotive electrics.

Ultradur B4335G3 HR HSP can protect sensitive electronics from extreme conditions, water and salt, the company said. The PBT incorporates additives designed to delay hydrolytic degradation, making it resistant to damage by water at elevated temperatures.

At the same time, a standard low moisture absorption of 0.2% is retained, which gives the material improved electrical insulation properties and good dimensional stability. It is also resistant to stress cracking caused by alkaline media.
