Features & Benefits
Exceptional High Heat Resistance
With a heat deflection temperature of 112°C, LG ABS XR470 maintains its structural integrity in hot environments, preventing warping or deformation in parts like dashboards and door panels.
Ultra-Low VOC for Healthier Interiors
This ABS XR470 LG Chem grade is formulated for low Total Volatile Organic Compound (TVOC) emissions, contributing to better interior air quality and meeting stringent environmental standards for vehicle cabins.
Robust Mechanical Strength
It offers an excellent balance of impact strength (110-130 J/m) and rigidity (Flexural Modulus 2500 MPa), ensuring durable, reliable parts that can withstand assembly stresses and in-use impacts.
Use & Applications
- Cockpit Modules (e.g., dashboard skeletons, instrument clusters)
- Door Trim Panels and interior hardware
- Other Automotive Interior Parts requiring high heat and low gloss
