Plastic is not always bad for an electric kettle, but low-grade plastic or poorly controlled plastic contact areas can create more risk in long-term use. The real issue is not the word plastic itself. The issue is whether the material is heat-resistant, food-contact compliant, and stable under repeated boiling conditions. For export markets, plastic food-contact materials are regulated under EU 10/2011, while kettle safety for appliances that heat liquids is covered by IEC 60335-2-15.
