WebEnvironmental an cost pressures require more and more materials to be recycleable, TPE processing scrap, reject parts or end of life products can be easily reprocessed, whereas most thermosetting elastomers end up as land fill. Additional advantages over thermoset rubber provided by TPEs include excellent colourability and a lower density. Web5 apr. 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.
