Priority should be given to choosing flame-retardant PC/ABS alloy for the outer shell of African lighting electrical Ready Board Box, and flame-retardant ABS should only be used when the budget is extremely tight and the environment is mild.

1、 Material selection conclusion

Africa has strong outdoor sunlight, large temperature differences, frequent sandstorms, and humid heat, which require high material weather resistance, impact resistance, and heat resistance. Flame retardant ABS has low cost and is easy to process, but it lacks heat resistance (≤ 80 ℃), impact resistance, and weather resistance, and is prone to aging and deformation. PC/ABS alloy is perfectly adapted to harsh environments and is the preferred choice for outdoor electrical ready boards.

2、 Core advantages of PC/ABS alloy

Weather resistance and heat resistance: Long term temperature resistance above 100 ℃, Vicat softening point 112-142 ℃, stable under cold and hot shock from -60 ℃ to 125 ℃; UV resistant, not prone to yellowing and brittleness, suitable for strong sunlight in Africa.

Excellent mechanical performance: The impact strength is about twice that of flame-retardant ABS (≥ 45kJ/m ²), with high strength and toughness, resistance to vibration and collision, and less prone to cracking and deformation during transportation and installation.

High flame retardant safety level: halogen-free flame retardant, reaching UL94 V0 level (1.5mm), thin parts (≤ 1.0mm) still maintain flame retardancy, self extinguishing without dripping, suppressing the spread of fire.

Dimensional stability and processing friendliness: Balancing PC rigidity and ABS fluidity, with good injection molding, precise size, smooth surface, suitable for complex structures and sealing designs, and high protection level.

Excellent insulation and corrosion resistance: The body has excellent insulation and leakage prevention; Resistant to moisture, salt spray, acid and alkali, suitable for outdoor polluted environments in Africa.

3. Summary

PC/ABS alloy has five core advantages of weather resistance, impact resistance, heat resistance, flame retardancy, and dimensional stability, fully adapting to harsh environments in Africa, ensuring long-term safe and reliable operation of electrical ready boards, and offering higher cost-effectiveness.
