SMILE ABS refers to a type of water heater or geyser that is made with ABS (Acrylonitrile Butadiene Styrene) plastic, a strong and durable thermoplastic material. ABS is known for its high impact resistance, making it ideal for creating sturdy and long-lasting appliances like water heaters. The SMILE ABS geyser combines the lightweight and corrosion-resistant qualities of ABS plastic with the efficiency of modern water heating technology.
