BASF has developed a material polybutylene terephthalate (PBT) Ultradur B4335G3 HR HSP which protects sensitive electronics which are critical in driving situations such as an emergency break. 

 

The PBT is equipped with highly effective additives that greatly delay hydrolytic degradation which makes the material resistant to damage by water at elevated temperatures. At the same time, the standard low moisture absorption of 0.2% is retained, which gives the PBT excellent electrical insulation properties and good dimensional stability. It is also resistant to stress cracking caused by alkaline media. Making the component more durable and reliable, which increases the safety standard.

 

The grade also benefits from being a high-speed product (HSP). This reduces the melt viscosity, which enables the production of thin-walled components.

 

"Ultradur B4335G3 HR HSP combines a number of strong properties into a unique profile. This makes it ideal for use in extremely challenging environments which sets Ultradur apart from comparable materials that are currently used," said Andreas Fay, Global Key Account Manager Transportation in BASF's Performance Materials division.

 

The new product grade represents a significant expansion of the Ultradur HR portfolio, with which BASF is successfully meeting the increasing demands placed on plastics in critical applications.
