ABS engineering plastic: The standard material for mainstream emergency radios on the market, characterized by its lightweight nature, impact resistance, and low cost; many outdoor disaster-preparedness models utilize this material for their casings.
Flame-retardant PVC: A specialized material often found in professional-grade emergency radios, offering drop resistance, waterproofing, and corrosion resistance. Some models incorporate flame-retardant additives to prevent combustion in high-temperature or fire environments, thereby reducing the risk of secondary hazards.
A select number of military-grade products feature localized metal reinforcements to further enhance structural strength and magnetic shielding capabilities.
The primary materials used in emergency radios fall into three main categories: the main housing, functional components, and internal core elements. Each material is selected to meet the durability and safety requirements of emergency scenarios:
