Sicomin Epoxy Systems commercially launched its GreenPoxy bio-based epoxy line, achieving up to 52% bio-sourced carbon content, and secured qualification with European wind turbine blade manufacturers between 2023 and 2024. Resin producers with validated bio-content certification and demonstrated mechanical equivalence to petroleum-based benchmarks will be best positioned, provided that feedstock supply chains for plant-derived precursors scale commensurately.

• Resin Type Analysis

Epoxy resins command 30.0% of the global thermosetting plastics market in 2026, equivalent to US$ 27.63 Billion, sustained by their unmatched combination of adhesion, chemical resistance, and electrical insulation performance across critical application categories. Electrical and electronics manufacturers select epoxy systems specifically for printed circuit board laminates, IPC-qualified FR-4 epoxy-glass substrates underpin virtually all rigid PCB production, and for potting and encapsulation of power electronics modules in EV inverters, where dielectric integrity under thermal cycling is non-negotiable. Wind energy developers similarly specify epoxy infusion resins for turbine blade fabrication, given demonstrated fatigue life superiority over polyester alternatives at blade lengths exceeding 80 metres.

Vinyl ester resins represent the fastest-growing resin segment, propelled by expanding deployment in corrosion-resistant process equipment, offshore infrastructure, and desalination plant pipework where superior hydrolytic resistance over standard polyester resins justifies the cost premium. INEOS Composites extended its Derakane vinyl ester resin product line in 2023 specifically targeting chemical processing and water treatment operators requiring ISO 14692-compliant glass-reinforced piping systems exposed to aggressive fluid environments.

• End-use Industry Analysis

The electrical and electronics sector accounts for 24.0% of the global thermosetting plastics market in 2026, equivalent to US$ 22.10 Billion, anchored by the sector's non-negotiable insulation, dimensional stability, and flame-retardancy requirements that only thermoset chemistries reliably satisfy at production scale. Semiconductor packaging manufacturers, including ASE Group and Amkor Technology, rely on epoxy moulding compounds to encapsulate integrated circuits, where post-cure rigidity and coefficient of thermal expansion matching prevent delamination during solder reflow. Data centre operators and EV charging infrastructure builders represent additional high-volume buyers, specifying phenolic and epoxy laminate boards for power distribution and control electronics.

Aerospace and defense is the fastest-growing end-use segment, driven by the structural weight reduction imperative across both commercial and military aviation platforms.
