Product Features

SAVI lubrication‑free EPM engineering plastic material features excellent impact resistance, vibration resistance and wear resistance with no additional lubrication required. Especially suited for applications demanding high‑level vibration damping, it is used for high‑frequency moving components in automotive seats and fitness equipment, as well as structures subject to continuous impact in packaging machinery. By absorbing vibration energy and reducing component wear through its inherent material properties, it improves equipment durability and operational stability.
