Specialty Acrylic Polymer Perfects Screen Visibility | plasticstoday.com - Plastics Today

A specialty acrylic integrative developed by Japan’s Asahi Kasei promises to present a superior optical acquisition for some passengers and drivers erstwhile viewing in-car displays. With fantabulous transparency and adjacent to zero birefringence from in- oregon out-of-plane retardation and photoelasticity (a measurement of birefringence nether mechanical stress), AZP resin produces molded parts that grounds fantabulous optical properties without the request for peculiar molding techniques, processing parameter conditions, oregon post-molding treatment. This besides contributes to higher productivity and state of design, including the quality to fabricate curved displays.

Launched past year, AZP resin has present transitioned to the signifier of commercialized availability and is targeting applications successful automotive heads-up displays (HUD) and halfway accusation displays (CID). Additionally, it is suitable for lenses and prisms successful virtual reality/augmented world (VR/AR) head-mounted displays.

Besides its optical properties, specified arsenic total airy transmittance of astir 92%, AZP besides offers vigor absorption arsenic evidenced by its solid modulation somesthesia (Tg) of astir 133℃, weatherability, debased density, and aboveground hardness characterized by a pencil hardness of astir 3H. The resin tin regenerate solid astatine a little strategy outgo connected relationship of its injection moldability.

As the metaverse draws greater attraction and related request for VR/AR head-mounted displays grows, and with HUD and CID becoming much wide utilized for enhanced information and convenience successful the automotive field, low-birefringence transparent polymers are indispensable optical materials for compact design, lighter weight, wider angles of view, higher definition, and improved visibility.

Birefringence, besides known arsenic treble refraction, is erstwhile a ray of airy splits into 2 arsenic it passes done definite types of materials. In optical terms, it presents arsenic a rainbow effect disposable to the quality eye.
