Segmentation by Product Type

The thermoset resin composites industry can be analyzed through its two primary product categories, each with distinct characteristics and market applications:

1. Sheet Molding Compound (SMC)

SMC materials consist of thermoset resins combined with chopped fiber reinforcement (typically 25-50mm glass fibers) and mineral fillers, processed through compression molding. This results in high-strength composite parts with superior surface finish and dimensional accuracy.

• Market Insight: SMC accounts for approximately 65% of the thermoset composites market by volume, with its dominant position in automotive applications driving this share. Its ability to reduce part weight by 30-50% compared to metal alternatives makes it particularly valuable in vehicle lightweighting strategies.

• Trend: The electric vehicle revolution is creating new opportunities for SMC in battery enclosures and structural components, where its electrical insulation properties and impact resistance provide distinct advantages over traditional materials.

2. Bulk Molding Compound (BMC)

BMC features shorter fiber reinforcement (typically 6-12mm) in a putty-like compound, making it ideal for intricate, high-precision components requiring excellent surface finish and dimensional stability.

• Market Insight: BMC holds about 35% market share, with strong positions in electrical/electronic applications. Its inherent flame retardancy and electrical insulation properties make it valuable for components in switches, connectors, and electrical enclosures.

• Trend: Growing implementation in 5G infrastructure components due to excellent RF transparency and weather resistance. Major telecommunications equipment manufacturers are increasingly specifying BMC for antenna housings and radomes.
