Material modification becomes a key competitive point for rail‑transit rubber damping products in 2026. Traditional natural‑rubber‑based parts easily suffer compression‑set, ageing and cracking after long‑time cyclic loading, leading to higher track and vehicle maintenance costs.

Many R&D teams blend EPDM, modified NR and functional filler additives to optimize compound formula. Improved anti‑ozone, anti‑aging and fatigue‑resistant performance effectively slow rubber performance degradation. Advanced vulcanization and metal‑rubber bonding processes further enhance interface adhesion strength between metal insert and elastomer.

These technical upgrades help components satisfy international UIC and EN standards, supporting both domestic new‑build metro lines and overseas rail‑equipment export businesses.
