Natasha. The use of epoxy resins is for coating materials, manufacturing insulating materials, etc. For example, Araldite. Thermosetting polymers are cross-linked or heavily branched polymers which get hardened during the molding process. Separate polymers are joined in order to form a huge polymer. Examples of thermosetting plastics are- melamine- used for making fire ressistant fabrics and floor tiles. Such a material is also known as a thermoset or thermosetting polymer. Most of the plastic that we see in our day to day life is Thermoplastic. Another example is Melamine which has a capacity to resist fire and heat much efficiently than other plastics. Thermosetting plastics such as polyurethane and epoxy resins, by contrast, cannot be remelted; these are usually ground or shredded for use as fillers or insulating materials. This forms the basis of many paints and varnishes. With a combination of thermal stability, performance, and chemical resistance, thermoset plastics are extensively used in a wide variety of industries—from the manufacturing of electrical components and durable manufactured goods to the aerospace industry, heavy duty construction equipment, the energy sector—including oil, gas, and solar—and automotive manufacturing.
