Atlas Material Testing Technology, the global leader in weathering testing technology, will make its first appearance at Polymer Testing World Expo, November 11–12, 2026, at the Huntington Convention Center of Cleveland, Ohio. At Booth T418, Atlas will highlight its industry-leading, xenon-arc weathering instruments and natural weathering testing services for the polymer industry.
Weathering testing of polymers must be practical and reliable for today’s needs of changing material formulations, different specimen sizes, and a wide range of end-use applications. When companies incorporate recycled content or modify resins, additives and stabilizers, they must determine if weathering performance still meets applicable specifications.
Plastics used in automotive components, building products, consumer electronics and photovoltaic modules also face different exposure conditions and performance requirements. Together, these factors increase the need for appropriate test methods and reliable, reproducible results.
“The key question in accelerated weathering is whether lab results correlate with real-world exposure,” said Dr. Oliver Rahäuser, Senior Product Manager at Atlas Material Testing Technology. “That’s why we recommend running benchmark outdoor exposures in parallel with laboratory testing. Once acceleration factors are established for a material, accelerated testing becomes a reliable tool for predicting service life.”
Atlas supports the full suite of weathering testing needs with our benchmark outdoor testing facilities around the world, our accredited accelerated weathering laboratories and our unmatched portfolio of xenon-arc weathering instruments. Frequently specified by OEMs, Atlas instruments serve as the foundation for many established test methods. Manufacturers can conduct testing in-house using Atlas instruments, outsource testing to Atlas or combine laboratory and outdoor exposure programs to evaluate new formulations and materials.
Recommended Solutions for Polymer Weathering Testing
Atlas offers a range of weathering instruments and natural exposure services to plastics and polymer manufacturers. Solutions include the Ci3000 Weather-Ometer®, which supports key plastics weathering standards, including ASTM D2565 and ISO 4892-2, with a two-tier rack accommodating up to 3,450 cm² of specimens; the SUNTEST® XXL, featuring a 3,000 cm² exposure area for molded plastics and other three-dimensional components; and the SUNTEST® XLS, a compact benchtop xenon instrument with optional water spray and immersion capabilities.
To complement laboratory testing, Atlas’ Natural Weathering Services provide outdoor exposure in South Florida and Arizona, including EMMA® and EMMAQUA® solar concentration programs, helping manufacturers assess how laboratory results correlate with real-world exposure.
Polymer Testing World Expo brings together manufacturers, suppliers and testing professionals from across the plastics industry. Co-located with Compounding World Expo, Plastics Extrusion World Expo and Plastics Recycling World Expo, the event provides attendees with opportunities to explore related technologies, gain insights into developments across the plastics value chain and connect with industry professionals. Admission is free. Visit Atlas at Booth T418 or learn more at www.atlas-mts.com.
