Guangzhou Winlane Material Technology Co., Ltd. has successfully finished the R&D of new‑formula flame‑retardant rubber‑metal damping components complying with EN45545‑2 railway fire safety standards.

The R&D team optimized modified EPDM blending formulation, balancing flame retardancy, low‑smoke‑low‑toxicity performance and long‑term fatigue resistance. A full set of third‑party lab tests have been passed for bogie elastic joints, traction rod bushes and rubber mounts.

These newly‑developed products are designed for metro and EMU vehicles. They will support both domestic urban rail projects and overseas rail‑equipment export businesses. According to the company, this technical achievement expands Winlane’s qualified product portfolio and strengthens its competitiveness in high‑end rail component bidding.
