non-metallic
Non-metallic materials are substances that do not exhibit the properties typically associated with metals, such as conductivity, malleability, and luster. These materials can be found in various forms, including solids, liquids, and gases. Common examples of non-metallic materials include plastic, glass, and rubber. They are often used in everyday items, construction, and packaging due to their versatility and lightweight nature.
In contrast to metals, non-metallic materials tend to be poor conductors of heat and electricity. This makes them useful in applications where insulation is required. Additionally, many non-metallic substances are resistant to corrosion and chemical reactions, making them ideal for use in harsh environments, such as chemical plants and laboratories.
