Polyplastics concentrates DURANEX (R) -PBT types on applications in autonomous driving
20 July 2020
While the automotive industry is making a major shift towards electric vehicles, Polyplastics Co., Ltd., a world leader in engineering plastics, sees great potential in its innovative resin products for components in Advanced Driver -Assistance systems (ADAS) that enable autonomous driving. The company's DURANEX (R) -PBT materials, which are intended for drive elements and communication devices, offer high durability, alkali resistance, hydrolysis resistance and thermal shock resistance.
In drive-by-wire systems, the actuator requires a higher level of reliability because the ADAS parts are becoming more sophisticated and electronic controls are automated. DURANEX (R) PBT from Polyplastics is used in many electrical actuator parts because it maintains its performance even in harsh environments. Underbody parts are exposed to water and snow melt from road surfaces as well as oil and other substances. These parts also heat up because they are close to the engine, travel drive, and other heat-generating parts. Therefore PBT is selected for many actuator parts due to its high heat resistance, its excellent chemical resistance and its low water absorption rate.
DURANEX (R) PBT 330HR, 531HS and 532AR are grades with the superior durability (hydrolysis resistance) to withstand such conditions. DURANEX 532AR offers resistance to alkali material and does not show any slight stress crack formation even when it comes into contact with metal rust liquid. This makes it ideal for auto parts on the underside of the vehicle.
Flame-retardant PBT resins are also in demand in communication devices for applications in motors that are exposed to high voltages, as well as batteries and charging parts. DURANEX (R) PBT 750AM is a UL V-0 type with high durability in vehicle-integrated environments. Since it also has the ability to stabilize the shapes of housings and connectors, in recent years this grade has been used increasingly in auto parts that have to be equipped with flame retardants.
