Thermoplastic curing

WebbThermoplastics Curing Process Thermoplastics pellets soften when heated and become more fluid as additional heat is applied. 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. WebbCuring Process Thermoset plastics undergo a fundamental chemical change during their curing process. They’re created using polymers that cross-link together during this process, which forms irreversible bonds. This chemical bond …

WebbAutoclave curing of composites applies a combination of vacuum and external pressure. The vacuum removes air and volatiles trapped within a laminate and the external pressure suppresses any remaining vapors into the resin matrix to prevent void formation. The cure pressure also helps to consolidate the plies, yielding high-quality parts. All ... WebbCuring does not always require heat; in some instances, all that is required is the addition of a curing agent, a catalyst, or a hardener. In contrast to thermoplastic polymers, which are frequently produced and distributed in the form of pellets and molded into the final product form by melting, pressing, or injection molding, thermoset polymers cannot be …
