Thermoset Composites Enhance Product Performance in Demanding Markets
Increasing performance demands in agriculture, automotive & heavy truck, construction, electrical, energy, HVAC, power generation, rapid transit, and safety & security industries, among others, plus the rising cost of metals and polymer-concrete, is prompting design engineers to use thermoset composite technology as a replacement for existing materials. Thermoset composite materials have many unique properties - exceptional strength, light weight, corrosion resistance, UV resistance, electrical non-conductance, and exceptional thermal properties. These composite material properties make thermosets a good polymer-concrete conversion and, in particular, a good choice for metals conversion, such as from cast steel and aluminum.

For instance, composites can be used outdoors and in extreme environments, as they will not rust or corrode. And, because many components can be molded along with the part, and require no final finishing, thermoset molding compounds are often more economical from a total manufacturing standpoint. With a better strength-to-weight ratio than most metals, thermoset composites are a reliable substitute for traditional materials. They are fast becoming the material of choice for design engineers looking to reduce cost in new high performance applications - because of their exceptional composites properties.

Metals Conversion
Thermoset Compounds are Cost Less Than MetalDue to the intrinsic limitations of metals as well as sky rocketing costs, many design engineers utilize thermoset composites as a replacement for metal for high-performance applications. Thermoset composites provide more strength, dimensional control, and corrosion resistance than metals, while increasing design flexibility and manufacturing efficiency. When used for metals conversion, thermoset composites, such as bulk molding compound (BMC), sheet molding compound (SMC) and Structural Thermoset Composites (STC®), offer the following benefits to metals conversion:

  • Substantial cost savings;
  • Significant parts consolidation;
  • Light weight;
  • UV resistance;
  • High impact strength;
  • Superior electrical insulation;
  • Molded-in color.
