🚆 SINOYQX Melamine Foam for Rail Manufacturing

Lightweight, Flame-Retardant Acoustic & Thermal Insulation for Modern Railway Vehicles

🌟 Overview

SINOYQX melamine foam is an advanced open-cell thermoset foam designed to meet the high safety and performance standards of rail transportation systems, including high-speed rail, metro, trams, and light rail vehicles.

From passenger comfort to system energy efficiency, it offers exceptional acoustic absorption, thermal insulation, fire resistance, and light weight—with multiple tailored solutions such as hydrophobic foam for HVAC, composite-laminated panels, and die-cut structural parts.

🔧 Why SINOYQX Melamine Foam for Rail?

🔊 NRC ≥ 0.85 Acoustic Performance
Strong mid–high frequency absorption, ideal for walls, ceilings, and equipment bays.
🌡 Thermal Insulation
Thermal conductivity ≤ 0.035 W/m·K — helps regulate cabin and equipment temperatures.
🔥 Railway Fire Safety Certified
Meets EN 45545-2, DIN 5510, TB/T 3237, and UL 94 V-0 for global rail use.
🪶 Ultra-Lightweight
Density from 4–12 kg/m³ — supports speed and energy efficiency targets.
🧪 Aging & Chemical Resistance
Maintains structure after 500 h @ 120 °C; resistant to fog, vibration, and cleaning agents.
