What Are the Key Benefits of Mylar® Washers?

Mylar® washers have many unique characteristics that are beneficial to certain applications. For example, they are excellent in electrical applications due to their insulating properties. When it comes to cost, they are a significantly less expensive option to Kapton for lower temperature applications. They are also very durable and wear-resistant, making them suitable for many high-vibration applications where a more rugged washer is required. Mylar® washers also exhibit dielectric properties and low moisture absorption as well as excellent chemical resistance.

Mylar®, as a material, can withstand a wide temperature range while maintaining its physical properties. It doesn’t contain plasticizers, which means that it will not become brittle as a result of extreme temperature exposure. It can be used in temperatures ranging from -70 to 150 °C (–94 to 302 °F); however, if the physical requirements of the application are not extremely demanding, Mylar® can be used in a wider temperature range of –250 to 200 °C (–418 to 392 °F). Additionally, it has significantly higher shear strength than other polymeric materials, such as acetals and nylons.

What Are the Common Applications of Mylar® Washers?

Mylar® washers are used in many industrial applications including electric, wind energy, marine, and nuclear applications. They are commonly used with duct insulation, lighting, and within the automotive industry. Mylar® washers can distribute a load between fasteners and create a barrier between a screw or bolt and the installation surface. They can also be used as spacers and as a means to reduce vibration. When it comes to reducing vibrations, Mylar® washers perform significantly better than metal substitutes, and they can also be used as a locking device.
