Surveillance, Security and Energy Sectors: In-depth Analysis of Materials Technology
1. Security and Surveillance Systems (Security & Surveillance – Rugged and High-Definition)
| Component Name | Recommended Materials | Key Technical Parameters (Typical Values) | Key Benefits / Addressing Pain Points |
| Surveillance Camera Housing | Weather-resistant PC/ABS | Impact Strength: ≥500 J/m | Long-lasting anti-ageing properties and high impact resistance: Ensures the camera lens does not yellow or become brittle when exposed to extreme sunlight outdoors. It also boasts exceptional toughness, capable of withstanding vandalism or environmental impacts (compliant with IK10 impact resistance rating). |
| UV Resistance Certification: UL 746C f1 | |||
| Optical Lens Cover | Optical-grade PC | Light Transmittance: ≥90% | Crystal-clear vision, robust and durable: Offers transparency comparable to glass, ensuring distortion-free and glare-free 4K/8K surveillance footage. Lighter and more impact-resistant than glass, it is the standard choice for outdoor dome and bullet cameras. |
| Refractive Index Stability: 1.586 | |||
| Precision Waterproof Connector | FR-PBT (flame-retardant) | Dielectric Strength: ≥30 kV/mm | Low water absorption, dimensionally stable: PBT absorbs virtually no water in humid environments, ensuring stable signal transmission. V-0 flame retardancy provides electrical safety for all-weather operation, preventing fires caused by short circuits. |
| Flame Retardancy Rating: UL94 V-0 |
2. Energy Sector (Energy: Photovoltaics/Energy Storage/EV – Safety and Temperature Resistance)
| Component Name | Recommended Materials | Key Technical Parameters (Typical Values) | Key Benefits / Addressing Pain Points |
| Solar Junction Box | PPO (modified polyphenylene oxide) | Long-term operating temperature (RTI): 110°C+ | High-temperature resistance and excellent insulation: The environment for rooftop photovoltaic systems is extremely harsh. PPO boasts an extremely high heat deflection temperature and weather resistance, effectively preventing arc breakdown when high-voltage currents pass through. |
| Tracking resistance index (CTI): 600 V | |||
| Battery Support | FR-PA66 (reinforced flame-retardant) | Flexural modulus: ≥9000 MPa | Robust support and fire isolation: Energy storage cells are extremely heavy and generate heat during operation. Reinforced PA66 provides steel-like structural strength and features V-0 fire resistance, serving as a critical defence against the spread of thermal runaway. |
| Flame retardancy rating: UL94 V-0 (1.5 mm) | |||
| Charging Station Housing | Flame-retardant weather-resistant PC/ABS | Vicat softening point: ≥110°C | Combining aesthetics with performance: Meets the requirements for precision moulding and vibrant colours in large-surface-area components of charging stations. Maintains high strength even in extremely cold regions, preventing fatigue damage to the housing caused by repeated insertion and removal of the charging gun. |
| Low-temperature impact (-30°C): No cracking |
