Product Features & Engineering Performance

  • Moderate glass fiber content brings good flowability, enabling one-step molding for thin-walled boxes, buckles and mounting bosses with stable dimensional accuracy.
  • Low water absorption provides moisture and waterproof performance, resisting swelling, delamination and cracking under long-term outdoor service.
  • Excellent electrical insulation and arc resistance to ensure safe operation of electrical components.
  • Heat deflection temperature ≥200℃, resistant to softening and deformation under direct sunlight.
  • Acid & alkali resistance, anti-aging and UV resistance; rust-free compared with metal enclosures and no extra painting required.
  • Sufficient impact resistance to protect internal meters and valves from collision damage.
  • Without flame retardant formulation, it offers cost advantages for civil outdoor boxes without mandatory flame retardant requirements.
