Eastman introduced Saflex Evoca XIR.SR, a next-generation infrared-reflective interlayer developed for panoramic sunroofs in electric vehicles.
Building on the company’s XIR technology platform, the new interlayer is designed to reduce solar heat gain while maintaining a neutral, angle-stable reflected color. According to Eastman, the product can help reduce HVAC load and support battery and range efficiency by lowering cabin temperatures.
The interlayer is now available globally.
Eastman said the new interlayer addresses increasing thermal loads in EV interiors, where seating positions are often closer to large panoramic glass roofs. The Evoca XIR.SR interlayer reflects infrared rays to lower total solar energy transmittance, helping improve occupant comfort while preserving optical clarity.
The product also eliminates the blue hue commonly associated with metal-coated glass by delivering a neutral-gray reflected color across different viewing angles and glass configurations.
“Developed alongside OEMs and laminators and validated across multiple sites, Saflex Evoca XIR.SR was engineered to deliver consistent color neutrality, support higher solar transmittance and eliminate optical defects like orange peel and wrinkling,” said Oliver Osborne, global commercial director of automotive interlayers at Eastman. “Evoca XIR.SR offers consistent, top-tier solar performance and appearance for laminators, so OEMs can rely on repeatable quality.”
Eastman said the interlayer provides flexibility for visible light transmission, haze levels, and solar control, allowing designers to balance daylighting and cabin appearance with thermal management needs.
The company also said the product offers an alternative to metal-coated glass in applications where coated solutions may not be feasible, helping suppliers meet OEM solar performance requirements.
The Evoca XIR.SR interlayer can also be paired with acoustic solar interlayers and neutral gray color options within the Saflex Evoca portfolio.
Eastman is exhibiting the new technology at the Beijing International Automotive Exhibition, running April 24 through May 3, 2026.
