Polyplastics Targets DURANEX(R) PBT Grades for Autonomous Driving Applications
TOKYO, July 14, 2020 /Kyodo JBN-AsiaNet/--

As the automotive industry makes a strong shift to electric vehicles, 
Polyplastics Co., Ltd., a leading global supplier of engineering plastics, sees 
strong potential for its innovative resin products in Advanced 
Driver-Assistance Systems (ADAS) parts that enable autonomous driving. The 
company's DURANEX(R) PBT materials--targeted for actuators and communications 
equipment--deliver strong durability, alkali resistance, hydrolysis resistance, 
and heat shock resistance.


In by-wire systems, the actuator requires a higher level of reliability as ADAS 
parts become more sophisticated and electronic controls become automated. 
Polyplastics' DURANEX(R) PBT is chosen for many electric actuator parts because 
it capably continues to perform even in harsh environments. Underbody parts are 
exposed to water and snow-melting agents from road surfaces as well as oil and 
other substances. These parts also heat up since they are close to the engine, 
motor, and other heat-generating parts. As a result, PBT is chosen in many 
actuator parts due to its high heat resistance, superior chemical resistance, 
and low rate of water absorption.

DURANEX(R) PBT 330HR, 531HS, and 532AR are grades with the superior durability 
(hydrolysis resistance) to withstand conditions such as these. DURANEX 532AR 
has resistance to alkali matter and does not easily experience stress cracking 
even when in contact with rust fluid from metal. This makes it optimal for 
parts on the underside of cars.

In communications equipment, flame-retardant PBT resins are also in demand in 
motor applications exposed to high voltages, batteries, and charging parts. 
DURANEX(R) PBT 750AM is a UL V-0 grade with a high level of durability in 
car-mounted environments. Since it also possesses the ability to stabilize the 
shapes of cases and connectors, this grade is increasingly being used in auto 
parts that require flame retardancy in recent years.
