Thermosets are materials which remain in a permanent solid state after being cured once. Polymers within the material ‘cross-link’ during the curing process to create an irreversible bond.  This means that thermosets will not melt, even when exposed to extremely high temperatures…unlike thermoplastics.  Thermosets will withstand heat and extreme cold and will not warp or lose their shape.  They are ideal for applications that will be used in harsh climates / environments that experience regular variation in temperature.

Thermosets have excellent ‘flow’, which makes for easier molding and shorter cycle times.  In addition, it allows for the creation of larger and / or more complex parts, along with part consolidation and varied wall thicknesses..  Dimensionally stable and structurally sound, impact resistance and strength are inherent traits of this material. They can be further strengthened during mixing with reinforcement materials such as fiberglass, carbon and Kevlar.  Chemical resistance, dielectric and insulative properties add to thermosets’ desirability and durability and they are a top choice for watercraft, insulation, medical and food contact applications.

Finally, aesthetics need not be compromised with thermoset materials.  Specialty finishes, coatings and molded-in high gloss colors offer innovative and attractive options.
