Plastic

Substance added to plastic during its manufacture to improve its properties or characteristics, such as increasing impact resistance, enhancing heat resistance, or retarding combustion.

Material used throughout history due to its diverse properties. They can be natural or synthetic, classified into thermosets, thermoplastics, and elastomers.

Synthetic material widely used in industry, produced from the polymerization of organic compounds, resulting in a hard and versatile substance.

Type of plastic that softens when heated and hardens when cooled, a process that can be repeated, allowing it to be molded or recycled.

Type of polymer that, once heated and molded, hardens permanently. It cannot be remelted or remolded; if reheated, it degrades or burns.
