Product Features & Engineering Performance

  • · Ultra-low shrinkage & superior dimensional stability: Shrinkage ≤0.05% brings tiny deformation after molding; no warpage or cracking under long-term vibration and temperature change, perfectly matching automatic precision assembly with good part interchangeability.
  • · Stable high-temperature resistance: HDT≥200℃ ensures structural stability without softening deformation under long-term high-temperature working conditions.
  • · Outstanding mechanical strength: Excellent tensile, flexural and impact strength provides strong anti-extrusion and anti-collision capacity for load-bearing protective structures.
  • · Moisture & corrosion resistance: Low water absorption avoids swelling; resistant to oil, mud, acid and alkali for long service life outdoors.
  • · Lightweight & easy molding: Integral compression molding realizes complex shaping; lighter than steel to reduce dead weight and energy consumption.
  • · Insulation & durability: Stable insulating performance and slow performance attenuation for long-term service.
