High Density Flexible PU Integral Skin Foam Armrest Pad

Engineered with an elongated profile, this high-density PU self-skinning armrest provides continuous, full-length support across the user’s forearm. The internal structural frame is custom-welded to handle high bending torques along the edges during heavy leverage. Produced using eco-friendly formulations, this long-bar pad offers excellent low-odor characteristics, uniform density, and clean aesthetic lines for premium vehicle interiors.

Parameter
Features
