Thermoset Materials
Thermosets as name suggest means "setting under heat". On heating they undergo
a molecular cross-linking process which is irreversible and once cured cannot be
reshaped or recycled. Because of their tightly crosslinked three-dimensional
structure thermosets retain their strength and shape even when heated, resist
higher temperatures providing greater dimensional stability, good rigidity, hardness
and resistance to creep.

Thermoset Materials
Name Properties Applications and Uses
Alkyds Excellent heat resistance, Electrical applications like circuit
dimensionally stable, excellent breaker insulation, switchgear,
dielectric strength, very low moisture cases, housings, capacitor and
absorption, No volatile by products resistor encapsulation, automotive
parts, and coatings
Silicones odorless, colorless, water resistant, lubricants, adhesives, sealants,
chemical resistant oxidation gaskets, pressure compensating
resistant, stable at high temperature, diaphragms for drip irrigation
and have weak forces of attraction, emitters, hydraulic fluids, electrical
low surface tension, low freezing insulators and moisture proofing
