Leaving Certificate Technology – Materials Practice Test

Thermoset materials form a strong, infusible network when cured, so they don’t melt or soften with heat. That gives them high heat resistance, rigidity, dimensional stability, and good electrical insulation. These properties make them ideal for applications across different sectors: automotive and industrial components that face heat and chemical exposure, electrical uses where insulation is crucial, and heat sealants and bonding resins in manufacturing. In kitchenware, traditional thermosets like melamine and bakelite provide durable, heat‑resistant surfaces and handles. Packaging and disposal aren’t typical fits because once cured they can’t be melted and remolded, which makes recycling and reprocessing difficult. Clothing and toys usually rely on thermoplastics that are easier to mold and rework.
