Thermoset plastics form the backbone of many high‑performance products thanks to their heat resistance, chemical stability and robust mechanical properties. Unlike thermoplastics, which soften when heated and can be melted and remoulded, thermoset plastic examples are designed to undergo a chemical cross‑linking reaction that creates a rigid three‑dimensional network. This cross‑linked structure makes them dimensionally…
