Electronics are an ever-present part of modern life, so they’re easily taken for granted. However, the circuit boards and other delicate components in cell phones, computers, and advanced medical equipment are extremely sensitive to temperature, impact, and static electricity. Polyurethane is an essential part of the electronics industry, making many of today’s technological marvels possible. Here’s a closer look.

How Polyurethane Helps the Electronics Industry

Potting Electronics

Fragile electronic components are often suspended in polyurethane resin, a process known as “potting.” When cured, these resins are extremely durable, offering superior scratch resistance and protecting the circuits from high temperatures, extreme cold, and water. These resins are also uniquely flexible, allowing manufacturers to tailor the composition to meet the needs of each individual project.

The Benefits of Polyurethane Resin

Specially formulated resins can easily tolerate temperatures as low as -94°F or as high as 275°F. Despite their durability and hardness, they’re also highly flexible when cured correctly, making them less likely to crack during use.

Unlike other types of resin, polyurethane doesn’t generate significant heat during the curing process, making it ideal for applications in which high temperatures can damage sensitive electronic components. Its cost-effectiveness makes this type of resin one of the most common compounds used in the potting process.

Where Resins Are Found

Based on their unique properties, these resins are used in a broad array of manufacturing processes. For instance, they often protect printed circuit boards as well as microelectronic components that require a specific electrical resistance. No matter what you’re building, polyurethane resin will play a critical role in your manufacturing process.
