Polyplastics Introduces New DURANEX(R) PBT Grade with Improved Hydrolysis Resistance and Heat Shock Performance
TOKYO, Sept. 15, 2020 /Kyodo JBN, AsiaNet/ --

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


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

DURANEX(R) 201HR complements Polyplastics' DURANEX(R) LT Series which also 
significantly improves heat shock resistance by enhancing toughness of resin as 
well as relaxing strain due to heat shock cycle testing. Its performance even 
surpasses that of polyphenylene sulfide(PPS) resin, known to be one of the top 
resins in terms of heat shock resistance. 

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

DURANEX(R) LT530HR is a 30% glass-filled resin while LT530FR is a 30% 
glass-filled grade which provides flame retardance.
