Thermoset plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. The cross-linking process eliminates the risk of the product remelting when heat is applied, making thermosets ideal for high-heat applications such as electronics and appliances.
Thermoset plastics significantly improve the material’s mechanical properties, providing enhanced chemical resistance, heat resistance and
More resistant to high temperatures than thermoplastics
Highly flexible design options
Thick to thin wall capabilities
Excellent aesthetic appearance
High levels of dimensional stability
Cannot be recycled
More difficult to surface finish
Cannot be remolded or reshaped
Thermoplastic pellets soften when heated and become more fluid as additional heat is applied. As the material is cooled it takes on the mold shape. The curing process is completely reversible as no chemical bonding takes place. This characteristic allows thermoplastics to be remolded and recycled without negatively affecting the material’s physical properties.
There are multiple thermoplastic resins that offer various performance benefits, but most materials commonly offer high strength, shrink-resistance and easy bendability. Depending on the resin, thermoplastics can be used for a variety of different applications including low-stress applications such as plastic bags or high-stress mechanical parts.
Aesthetically superior finishes
Hard crystalline or rubbery surface options available
Generally, less expensive than thermoset
Can melt if heated
