Plastic molding technology began with thermoset materials. Through the years, in spite of the proliferation of new thermoplastic materials, thermosets have continued to fill an important niche, particularly in the automotive, electrical and appliance markets. Today, through advances in materials and processing, they're better than ever. Thermosets have become a lighter weight, more versatile and lower cost replacement for metal in many high heat applications. They can also be a cost-effective, dimensionally stable alternative to high performance thermoplastic materials.
