Unlike traditional metal cabinets, ABS is a non-metallic material, which fundamentally eliminates the risk of oxidation and rust. Metal speakers are prone to rust due to electrochemical reactions in humid environments, resulting in reduced structural strength or damaged appearance, while ABS materials can maintain surface integrity for a long time without additional anti-rust coating.

The ABS of the 5" PA Sound System Hanging Pendant Speaker has excellent tolerance to environments such as water vapor and salt spray. The styrene component in its molecular chain can effectively block moisture penetration and avoid material expansion or deformation caused by long-term humidity. For example, in the high-salinity air environment in coastal areas, metal parts may accelerate corrosion due to salt adhesion, while ABS cabinets can maintain stable physical properties.

ABS has high resistance to weak acids, weak alkalis and common organic solvents. This feature makes it suitable for places that require frequent cleaning and disinfection, such as hospital operating rooms, laboratory workbenches, etc., and there is no need to worry about chemical corrosion or fading on the cabinet surface after spraying detergent.

Based on the above material characteristics, the speaker can be safely used in the following scenarios with high requirements for rust and corrosion resistance. The humidity in swimming pools, saunas, greenhouses and other places is higher than 80% for a long time. Traditional metal boxes are prone to condensation and rust, while ABS boxes can not only resist water vapor erosion, but its sealed structure can also prevent the internal circuit from being damp and short-circuited. For example, the changing area of ​​the swimming pool often causes equipment failure due to water vapor, and ABS material can significantly extend the service life of the speaker.

Food processing workshops, chemical plant warehouses and other places may be exposed to grease, acidic gas or alkaline dust. ABS material has better tolerance to such media than ordinary plastics, and the surface of the box is not easy to produce scratches or permeability damage, while avoiding the conductive safety hazards caused by corrosion of metal materials.

Chlorine-containing disinfectants or hydrogen peroxide solutions are required to clean the surface of equipment regularly in areas such as hospital corridors and biological laboratories. ABS boxes can withstand conventional disinfection processes, and the surface is smooth and non-porous, and it is not easy to leave residual bacteria, taking into account both health safety and equipment protection.

Coastal open-air corridors, semi-open stations and other places need to deal with rain, salt spray and ultraviolet radiation at the same time. ABS material can maintain a deformation rate of less than 1% in the temperature range of -20℃ to 60℃. Its anti-UV modified formula can also slow down sunlight aging and avoid brittle cracking of the box.
