Premium Acrylic (PMMA) & Polycarbonate Sheets & Filters
Customized acrylic sheets and finished parts,
manufactured for a wide range of applications.
Who We Are
Specialty Acrylic (PMMA) and Polycarbonate Sheets and Finished Parts
Founded in 1977, Astra Products Inc. is the North American sales agency for CLAREX custom optical-grade cell-cast acrylic (PMMA) sheets, manufactured by Nitto Jushi Kogyo (NJK) in Japan. We stock a wide range of common CLAREX configurations at our New York warehouse and can supply custom orders—ranging from a single sheet to mass production—typically within 4–8 weeks.
With extensive expertise in CLAREX and other coated materials, we provide personalized support from samples and prototypes to full production runs, helping you choose the right materials and customizations for your application.
If CLAREX isn’t the best fit, we also offer a variety of domestic and imported coated acrylic and polycarbonate sheets. Additionally, we provide finished parts, fabricated either at our ISO- and IATF-certified New York facility or through trusted partners.
PRODUCT SERIES
Specialized Optical Cell Cast Acrylic Sheets & Filters
Anti-Reflective (AR) Filters
Optical coatings physically reduce reflections to boost transmission, and can be tuned for applications like NIR and UV.
Precision Thin Sheets
Optical-grade cell-cast PMMA is available from 0.2 to 5.0 mm thick and can be fully customized with colors, formulations, textures, hard-coat, and optical coatings.
Near-Infrared (NIR) Filters
Optical-grade cast acrylic NIR filters transmit NIR while blocking visible light, with multiple transmission curves and full customization for your application.
DR-III Bulk Diffusers
Cast acrylic bulk diffusers offer 5% to 93% transmission in 5% increments to optimize backlight uniformity and brightness, with customization for your application.
Non-Glare (AG) Filters
Non-glare filters use textured surfaces to diffuse reflections, with multiple display-grade textures and full customization, including hard-coat and optical coatings.
Coated Polycarbonate (PC)
High optical quality hard-coated polycarbonate sheets deliver CLAREX-level clarity and can be customized with non-glare textures and anti-reflective coatings.
THE CLAREX DIFFERENCE
What sets CLAREX apart?
The CLAREX Acrylic/PMMA sheets are cell-cast. Compared to other manufacturing methods like extrusion and continuous-cast, cell-casting typically yields better optical quality sheets and allows for more customization.
CLAREX takes things a step further to ensure that the sheets are of the absolute highest quality, making them the best option for your unique and demanding applications.
| Product Comparison | CLAREX Cell-Cast | Commercial Grade Cast | Extruded |
|---|---|---|---|
| Thickness | • 0.2 – 5.0mm (0.008 – 0.197″) • Many options available | • 3.0mm (0.118″) and up • Can be produced very thick | • 0.8 – 12.0mm (0.031-0.236″) |
| Optical Quality | BEST • True optical grade • 100% visible inspection • Highly polished surfaces • No birefringence | Better | Good |
| Customization | • Can be made custom in low volumes up to mass production • Many customizable features | • Limited customizations available for mid/high volume orders | • Limited customizations available for high volume orders |
Customization
Custom sheets & parts to meet the needs of your applications.
Build your own sheets. Do you have a unique design requirement that cannot be met with off-the-shelf UV filter sheet materials? CLAREX acrylic can be fully customized and produced from low-volume runs to mass production. Select thickness, formulation, additives, pigments, textures, surface coatings, and optical coatings to create thin acrylic sheets tailored to your application.
Typical lead time is 4–8 weeks. Finished parts and assemblies can also be fabricated to specification.
Fabrication Capabilities
We can supply finished parts in addition to full sheets.
CNC Laser Cutting & Etching
Our precision CO2 laser cutters are great for cutting 2D profiles and features out of acrylic and other materials. They can also be used to etch the surface.
CNC 2.5D End Mill Routing
We’ll use the CNC Routers for parts that have a 2.5D feature, such as pocket or step cuts, and for materials that don’t laser well, such as polycarbonate.
Adhesive Application
We’re able to apply adhesive to selected areas of the finished parts.
Trusted Partners
We work with several different partners for processes we cannot do ourselves, including optical coatings, printing, & lamination.
Applications
Supplying Acrylic Sheets to a Wide Array of Industries & Applications
Barcode Scanner Filters
Gain exceptional optical clarity and accurate reading of barcodes even in varying lighting conditions. Materials with durability and resistance to scratches help maintain the scanner’s performance and longevity.
Backlight Diffusers
With a range of bulk diffusers available from 5% to 93% transmission in 5% increments, you can choose the transmission level for optimal uniformity and brightness of your display. The CLAREX diffusers are also popular in lighting applications for precision imaging due to to the pure white color.
Automotive Displays
Enhance the readability of dashboards and infotainment systems, even in direct sunlight. Impact resistance materials ensure that these critical components remain protected during everyday use.
Flat Panel Displays
Enhance the clarity and brightness of your flat panel displays and provide a superior viewing experience. Our materials’ protective properties help guard against scratches and impact, ensuring long-lasting performance.
