Thermoset Injection Molding

Thermosetting plastics are distinguished by the fact that they are capable of forming an infusible cross-linked or network structure by an irreversible chemical reaction. As a consequence, thermosets inherently possess excellent mechanical and heat-resistance properties. Their performance characteristics at elevated temperatures are generally superior to those of thermoplastic polymers. Despite these positive attributes, thermosets currently occupy about 18% of the plastics market in the United States [ 1 ]. Undoubtedly, difficulties associated with the processability of these materials have limited their penetration in many conventional markets.
