Webb22 juli 2024 · Thermoplastics, which make up about 75 percent of worldwide plastic production, can be recycled by heating them again until they become liquid, so they can be remolded into a new shape. Thermoset plastics are made by a similar process, but once they are cooled from a liquid into a solid, it is very difficult to return them to a liquid state. WebbLearn the basics about thermosetting and thermosoftening polymers, when learning about polymers as a part of organic chemistry. A polymer is a macromolecule made of many monomers, or repeating...
