Features & Benefits
Exceptional Heat Resistance
With a Heat Deflection Temperature of 102°C, ABS XR440 LG Chem ensures dimensional stability in high-temperature environments like car interiors under the sun, preventing warping or softening.
Low Gloss, No Painting Needed
The material’s inherent low-gloss surface eliminates the need for costly and environmentally impactful painting processes. This speeds up production and reduces VOC emissions from your factory.
Certified Low VOC Emission
LG ABS XR440 is specifically formulated for low Total Volatile Organic Compound (TVOC) content, helping your final products, such as car cockpits, easily comply with indoor air quality regulations.
