BASF launches Ultradur B4335G3 HR HSP – all-rounder for reliable protection.
- PBT impresses with a unique combination of different properties such as outstanding hydrolysis resistance and good flowability
- Safety for sensitive electronics in extremely challenging environments
With the polybutylene terephthalate (PBT) Ultradur B4335G3 HR HSP, BASF has developed a material that protects sensitive electronics from such influences. The unique combination of various properties sets Ultradur® apart from alternative materials.
Increase in safety standard
The PBT is equipped with highly effective additives that greatly delay hydrolytic degradation. This 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.
Suitable for the most demanding conditions
"Ultradur B4335G3 HR HSP combines a number of strong properties into a unique profile. This makes it ideal for the 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.
