Product technical features:

• Density as low as 1.0–1.2 g/cm³ — approximately 60% lighter than aluminum alloy and 80% lighter than steel. A single housing can be reduced in weight by 30%–40%.
  

• Tensile strength exceeds 70 MPa, flexural modulus exceeds 5 GPa, and impact strength reaches 26 kJ/m², meeting the vibration requirements of coaches at high speed.

• The “几”-shaped (bracket-shaped) reinforcing ribs effectively control housing deformation, making it especially suitable for heavy-load areas such as condensers.

• Operates stably across a wide temperature range of -40°C to 120°C, adapting to the all-weather operating environment of coaches.

• The material resists acid, alkali and salt erosion, especially suitable for coastal high-salt-fog areas and regions using winter de-icing agents.

• The material is fire-retardant, compliant with bus interior fire-safety standards, and releases no toxic gases when burned.

• Through acoustic material optimization, air conditioning operating noise is reduced by approximately 2 dB, improving passenger comfort.
