Composites for Electrical Materials

Various electrical industries depend on thermoset composites to manufacture products or produce energy. These materials have a range of heavy-duty properties that make them suitable for demanding applications. If you manufacture electrical products, consider the benefits of using thermoset composites. 

Why Electrical Industries Use Thermoset Composites

Thermoset plastics possess a long list of desirable properties, including:

Arc Resistance

When manufacturing certain electrical components, it’s essential to use materials that prevent electrical arcs. Since composites have insulating properties, they can withstand high voltages and electrical arcs. Thermoset plastic components will retain their insulation even after an arc has occurred, keeping the electrical system functional.  

High-Strength-To-Weight Ratio

Thermoset plastics are incredibly light without sacrificing strength. These materials weigh less than most wood or metal parts and are almost twice as strong as aluminum. This high-strength-to-weight ratio makes thermoset plastics ideal for products that need a high-power output. 

Corrosion Resistance

Since thermoset plastics aren’t made from metal, they do not corrode in the presence of strong chemicals or water. These corrosion-resistant properties ensure that electrical composite materials hold up in environments with excessive moisture and acidic chemicals. 

Extreme Temperature Tolerance

Another benefit of their insulating properties is that thermoset composites can withstand high temperatures without weakening. Some thermosets can experience temperatures of 428 degrees Fahrenheit (220 degrees Celsius). 

UV Resistance 

Many electrical industries need a material that can endure harsh sunlight for long periods while retaining its color and structural integrity. Thermoset electrical plastics are resistant to UV rays, allowing them to tolerate intense exposure to sunlight. 


Another advantage of using thermosets in electrical composites is that they are non-conductive and won’t interfere with sensitive electronic equipment, radio waves, and microwaves. 

How Electrical Industries Use Thermoset Composites

Whether producing electrical components or generating power, the unique properties of thermoset composites offer quality, efficiency, and durability to many electrical companies. Here are a few specific industries that rely on the favorable properties of thermoset composites:

  • Electric vehicles (EVs): Electric vehicles depend on lightweight materials to get more mileage on a single charge, so the high-strength-to-weight ratio of thermoset plastics makes them ideal for EVs. 
  • Power generation: Since thermoset composites can endure harsh UV exposure and high temperatures, they offer the power generation industry many benefits.
  • Electronic devices: Thermoset plastics’ non-conductive and insulating properties provide a suitable material for electronic devices since they prevent electrical arcs and magnetic interference.
