Materials for ADAS in-vehicle camera barrels, lens spacers, and housings XP640/AA105 (development product)/DG040
Performance requirements for resin materials used in ADAS cameras
For automotive camera applications, materials that achieve a high level of well-balanced properties are required.
- dimensional stability ⇒ Precise optical properties
- strength ⇒ Reliability in long-term use
- Joint characteristics ⇒ Reliability of joints
- Weather resistance ⇒ Reliability and design for outdoor use
XYRON™ XP640/AA105 (development product)/DG040 with excellent dimensional accuracy and dimensional stability (roundness)
We offer Asahi Kasei 's modified PPE resins XYRON™ XP640, AA105 (development product), and DG040 for lens barrels, lens spacers, and housings used in various cameras installed in automobiles.
As shown in the figure below, we conducted an aging test on the shape of the lens barrel and measured how accurate the shape was (roundness). It can be seen that XYRON™ DG040 is a material with particularly excellent dimensional stability, with high roundness from the initial state and little change due to aging. In addition, the dimensional stability changes of XYRON™
■ XYRON™ XP640, AA105 (under development)
It is an alloy grade of high heat resistant polyamide (PPA) and PPE. By alloying PPE, which is characterized by its low water absorption properties, with PPA, we have suppressed dimensional changes due to water absorption and achieved high heat resistance and high strength equivalent to PPA. AA105 (under development) is a grade with superior weather resistance and high light transmittance that can be used for laser welding compared to XP640.

■ XYRON™ DG040
Alloy grade of PPS and PPE. It is characterized by a small decrease in mechanical strength in high-temperature environments, and by containing a special glass filler, the anisotropy of dimensional changes is small.
