Polyplastics introduces new PBT DURANEX (R) grade with improved hydrolysis resistance and heat shock and performance

19 September 2020

Polyplastics Group has launched a new DURANEX (R) polybutylene terephthalate (PBT) grade that delivers significant improvements in hydrolysis resistance and heat shock resistance for a variety of applications. DURANEX (R) 201HR is a new offering that guarantees long-term reliability of parts and expands the penetration of PBT DURANEX (R) in the automotive markets.

DURANEX (R) 201HR is an unfilled material that dramatically improves resistance to hydrolysis, which is an issue in the molecular structure of resins, while maintaining the excellent mechanical and molding properties of conventional PBT resins. Ideal for use in high humidity environments, the DURANEX (R) 201HR can extend the life of a wide range of products. It is particularly well suited for automotive connectors in harsh operating environments.

The DURANEX (R) 201HR complements the LT DURANEX (R) Series from Polyplastics, which also significantly improves heat shock resistance by improving the hardness of the resin as well as relieving stress due to the heat shock cycle test. Its performance surpasses even that of polyphenylene sulfide resin (PPS), known as one of the best resins in terms of resistance to heat shock.

The LT Series from DURANEX (R) facilitates mold insertion and also has superior hydrolysis resistance, revealing the potential for high performance and longer life in a wide range of products. These grades can also be used on a wide range of parts for which conventional PBT resin was not an option. The LT DURANEX (R) Series of materials is well suited for use in parts for power modules, DC / DC converters, motor isolators, and EPS systems, which are subject to harsh environments.

DURANEX (R) LT530HR is a resin with 30% glass fill, while LT530FR is a grade with 30% glass fill that is flame retardant.
