Features & Benefits
Ultra-High Heat Resistance
With a heat deflection temperature of 106°C, XR490 withstands intense summer heat inside vehicles, preventing warping or softening in parts like dashboards and door panels, ensuring long-term dimensional stability.
Low-Gloss, Non-Paint Surface
This grade is formulated for a low-gloss aesthetic straight out of the mold. This eliminates the need for painting, reducing production costs, simplifying your assembly process, and avoiding VOC emissions from paint lines.
Low VOC for Cabin Air Quality
XR490 is designed with low total volatile organic compound (TVOC) content. This directly contributes to meeting stringent indoor air quality standards for modern vehicles, creating a healthier and more comfortable environment for passengers.
Use & Applications
