Why Thermosets Are a Go-To Material for Utilities and Power Grid Applications

Thermoset materials are a trusted choice across the Utilities and Power Grid industries, thanks to their exceptional resistance to heat, corrosion, and harsh environmental conditions. Designed to endure everything from snow and rain to extreme heat, thermoset-molded components offer long-term durability in demanding outdoor applications.

Original Equipment Manufacturers (OEMs) frequently use thermosets for critical electrical protection. These materials play a key role in keeping power lines operational, even in aggressive outdoor environments. Common uses include electrical housings and enclosures that shield sensitive electronics and wiring. Thermosets are also found in circuit breakers and power blocks, where they help safeguard internal components while providing a safer handling experience for utility workers during installation and maintenance.

Rethinking Plastics: Why Thermosets Deserve a Second Look

When most people think of plastic recycling, they picture soda bottles, food containers, or grocery bags—items made from thermoplastics. But another class of plastics plays a critical role in modern manufacturing: thermosets.

Known for their strength, heat resistance, and long-term durability, thermosets are widely used in high-performance applications such as automotive components, wind turbine blades, electronics, and electrical systems. For years, their biggest drawback was recyclability—or rather, the lack of it.

That’s changing. Thanks to recent innovations, thermosets are emerging as viable candidates for circular manufacturing. At Woodland Plastics, we’re closely monitoring this transformation and preparing for what’s next.

Thermoplastics vs. Thermosets: What’s the Difference?

Understanding the difference between these two material families helps explain why thermosets were historically excluded from recycling programs.

Thermoplastics:
• Can be melted and reshaped repeatedly
• Easily recyclable through conventional systems
• Common in consumer packaging and disposable goods

Thermosets:
• Cure into a permanent, rigid structure
• Cannot be remelted or reshaped
• Known for exceptional durability, heat resistance, and mechanical strength
• Often reinforced with fiberglass or carbon fiber for added performance

These properties make thermosets ideal for demanding environments—but they’ve also made recycling a challenge. Until now.

The Thermoset Recycling Revolution

New technologies are rewriting the rules and opening doors to sustainable reuse:

1. Mechanical Recycling
Thermosets are ground into powders or fibers and reused as filler in new composite materials. While not full material recovery, this method extends product life and diverts waste from landfills.

2. Chemical Recycling
Advanced processes such as pyrolysis and solvolysis break thermosets down into reusable resins and recovered fibers—even from reinforced composites. This enables the reuse of parts like circuit boards and automotive components in entirely new applications.

3. Thermal Recovery
When direct recycling isn’t feasible, controlled incineration can recover energy from thermosets—supporting waste-to-energy systems and reducing landfill dependency.

Emerging Innovations Worth Watching

The science behind thermoset recycling is evolving rapidly.

Key breakthroughs include:
• Bio-tailored thermosets that degrade with enzymes
• Orthogonal polymerization enabling full material recovery from a single monomer
• Cryogenic grinding for efficient reuse of fiber-reinforced composites
• Dynamic covalent networks (CANs) that allow reshaping and repair of cured thermosets

These advancements are redefining possibilities across the industry. Woodland Plastics is committed to staying ahead of the curve by supporting these efforts and actively exploring future participation.

We remain dedicated to:
• Staying informed on emerging technologies
• Advancing sustainable design and sourcing practices
• Partnering with customers who prioritize circular manufacturing

Why It Matters

Although thermosets account for only 15–20% of global plastic use, they are essential in high-value, high-performance applications.

Recycling them supports:
• Reduced raw material extraction
• Lower greenhouse gas emissions
• More sustainable manufacturing across industries

Recyclability is no longer a barrier to thermoset adoption. With new recovery methods emerging, these high-performance materials are ready for reconsideration. The future of thermosets is not just durable—it’s recyclable.
