How Fluoropolymer Coating Helps with Electrical Insulation

Posted by Jon Goodwin on Apr 7, 2017 3:15:28 PM

Coating Products Offer Superior Quality and Reliability as Insulators

First, let’s have a quick review of fluoropolymer coatings. You are probably familiar with the most widely known properties of fluoropolymer coatings:

  • Non-stick
  • Low friction
  • Non-wetting
  • Thermal stability
  • Electrical insulation
  • Chemical resistance

You might be aware of the many ways choosing the right coatings can improve outputs and overall product performance. When you use the correct selection and application of a fluoropolymer coating, you can add significant value to your parts. 

The correct coating can increase: 

  • Up time and profitability in many applications, due to enhanced durability
  • Component life spans
  • Product yields
  • Repeatability

The correct coating can decrease:

  • Rejected product
  • Decreased cycle times
  • Periodic maintenance

 Fluoropolymer Coatings as Electrical Insulators

Here’s a did you know? for you: any substrate can be coated to insulate up to 5,000 volts. Different coatings are suited for several industrial and medical applications. Some of these applications include:

  • Medical instruments used for cauterization
  • Fixtures for plating
  • Protection against charged elements—in material, such as cooling tubes

The coatings also offer cross-functional benefits like release, chemical protection, and wear resistance. With this perfect balance of properties, these coatings are durable and deliver reliable performance even in the most demanding environments. Whether it’s for a large industrial electrical application or a small, tight-tolerance, electronic, these coatings can insulate for high-voltage requirements and power your products.

These high-performance coatings can be used in a variety of electronic and electrical environments:

  • Transformers
  • Motors
  • Relays
  • Switches
  • Sensors
  • Encapsulated coils
  • Components

American Durafilm® offers a wide range of fluoropolymer coatings that maintain their integrity from below freezing up to 500° F. There are both FDA and non-FDA compliant coatings that can do this. These coatings are in the Chemours® Teflon® group, and we use several others, such as Halar®, Whitford’s Dykor®, and polyurethanes. 

American Durafilm® is the oldest and most experienced licensed applicator of Chemours™ Teflon® coatings in the United States. We are an approved applicator of Whitford™ coatings, such as Dykor®, and also Halar®, Emralon®, Everlube®, MolyKote®, and hundreds of other functional coatings designed to improve and enhance the performance of your products.
