Melamine resins are often used in the production of laminates, decorative panels, and tableware, where both performance and aesthetics are essential.

Others

The "others" segment, including specialty resins like silicone, cyanate esters, and alkyds, accounts for approximately 3–5% of the market. These high-performance materials are used in industries such as aerospace, medical devices, and electronics, where extreme conditions demand materials with exceptional thermal, chemical, or mechanical properties.

Thermoset Molding Compound Market, Segmentation by End-User

The Thermoset Molding Compound Market has been segmented by End-User into Automotive, Aerospace, Electrical & Electronics and Others.

Automotive

The automotive industry represents the largest end-user segment in the thermoset molding compound market, holding an estimated 35–40% share. Thermoset materials are extensively used in under-the-hood components, brake systems, and structural parts due to their heat resistance, mechanical strength, and lightweight properties. As vehicle manufacturers push for fuel efficiency and durable alternatives to metals, demand for thermoset composites continues to rise.

Aerospace

The aerospace sector contributes approximately 20–25% to the market, utilizing thermoset molding compounds for interior panels, engine components, and structural reinforcements. These materials are favored for their low weight-to-strength ratio, flame retardancy, and resistance to high temperatures. With growing investments in aircraft manufacturing and defense aviation, this segment is poised for steady expansion.

Electrical & Electronics

Making up about 25–30% of the total market, the electrical and electronics industry relies heavily on thermoset molding compounds for insulation, circuit protection, and electronic enclosures. Their excellent dielectric strength and thermal stability make them ideal for connectors, switches, and printed circuit boards (PCBs) in both consumer and industrial electronics.

Others

The others segment includes emerging applications in industries such as construction, marine, and consumer goods, collectively accounting for around 5–10% of the market. In these areas, thermoset molding compounds are used for high-durability components, decorative laminates, and composite panels, especially where performance under mechanical or thermal stress is critical.

Drivers

• Rising demand in electrical insulation
• Growth in lightweight automotive parts
• Superior thermal and chemical resistance

• Increased adoption in household appliances - Thermoset molding compounds in household appliances are significantly driving global market growth. These materials are widely used in components for washing machines, microwaves, blenders, coffee makers, and irons due to their superior thermal stability, dimensional integrity, and electrical insulation. Their resistance to heat deformation makes them especially valuable in appliances operating under high-temperature conditions.

  Durability, rigidity, and chemical resistance give thermoset compounds a performance edge over many thermoplastics. Manufacturers favor them for their long-term reliability and safety under repeated use. Their consistency in high-volume manufacturing also supports cost-efficiency and quality control in appliance production.

  Rising consumer demand for energy-efficient and durable appliances is pushing manufacturers to adopt thermoset materials more broadly. Their compatibility with complex molding techniques allows for the creation of detailed, high-performance components that support innovation in appliance design.

  As the household electronics market focuses on longevity, safety, and cost-effectiveness, thermoset molding compounds are well-positioned for continued adoption. Their ability to enhance appliance performance and lifespan ensures growing relevance in global manufacturing.

Restraints

• Complex processing and long curing time
• Difficulty in recycling and reprocessing
• High tooling and mold preparation costs

• Emission of hazardous substances during curing - Hazardous substance emissions during curing pose a major challenge to the thermoset molding compound market. The curing of thermoset resins can release volatile organic compounds (VOCs), formaldehyde, and other pollutants, raising significant concerns about worker safety and environmental impact, especially in high-volume manufacturing settings.

  Compliance with environmental regulations often requires the installation of advanced ventilation systems and adoption of strict protective measures, increasing operating costs—particularly for small and medium-sized enterprises. As industrial emission regulations tighten, manufacturers face pressure to explore cleaner alternatives or risk limitations in environmentally sensitive applications.

  Low-emission and eco-friendly thermoset options are in development, but issues around processing efficiency and commercial viability limit their adoption. Many alternatives require longer curing times or come at a higher cost, making them less attractive for use in cost-sensitive production environments.

  Until scalable, emission-free technologies become mainstream, environmental and occupational safety concerns will continue to restrict market expansion. Thermoset producers must accelerate their transition to sustainable practices to remain competitive and compliant in increasingly regulated global markets.

Opportunities

• Innovation in eco-friendly thermoset resins
• Expansion in aerospace composite applications
• Demand for miniaturized electronic components

• Growth in sustainable mobility solutions - Sustainable mobility initiatives are opening new opportunities for thermoset molding compounds. As industries pivot toward lightweight, energy-efficient, and low-emission vehicle designs, these materials are being increasingly adopted in electric vehicle (EV) components, public transit infrastructure, and advanced automotive systems. Their heat resistance, mechanical strength, and long-term durability make them well-suited for modern transport technologies.

  Thermoset applications include engine covers, battery casings, structural reinforcements, and electrical insulation components, where they outperform metals by reducing weight without compromising safety. These advantages contribute to improved fuel efficiency and extended EV range, aligning with global sustainability and emissions-reduction goals.

  With rising investment in e-mobility and clean transportation infrastructure, demand for thermoset materials is growing rapidly. Their compatibility with automated, high-volume production supports scalable implementation across next-generation vehicle platforms.

  As the automotive industry embraces climate-conscious design and performance optimization, thermoset molding compounds are becoming critical enablers of innovation, helping manufacturers meet regulatory and consumer expectations for green mobility.
