Frequently Asked Questions
Do you have questions about dielectric EPDM? At Everest Group, we have compiled the most common questions and their answers for you. Just select a question and you will see the answer immediately.
Dielectric EPDM (Ethylene Propylene Diene Monomer) is a synthetic elastomer with excellent dielectric properties and superior weather resistance. It is primarily used in electrical applications for insulation, transformer seals, substation components, as well as seals and gaskets for construction and automotive where resistance to ozone, UV, and extreme weather conditions is required.
Everest Group's dielectric EPDM has a minimum dielectric strength of 10 kV/mm, meaning it can withstand up to 10,000 volts per millimeter of thickness without electrical current passing through. This makes it ideal for electrical insulation applications in substations, transformers, and distribution equipment.
The main difference between dielectric EPDM and standard dielectric rubber (typically neoprene) lies in their weather resistance and temperature range. EPDM offers superior ozone and UV resistance with a temperature range of -20°C to 145°C, while conventional dielectric rubber (neoprene) has lower ozone resistance and a temperature range of -20°C to 90°C. Dielectric EPDM is the preferred choice for outdoor applications and severe weather conditions.
Dielectric EPDM is available in rolls and sheets in different thicknesses and sizes to suit each project's needs. We also offer custom cutting and custom seal and gasket fabrication. To learn about available options and receive a personalized quote, we invite you to contact us.
Yes, absolutely. Dielectric EPDM is known for its superior ozone and weather resistance. Per ASTM D1149, it shows no cracks after 72 hours of exposure to 200 PPCM ozone at 40°C. It also resists UV rays, rain, and temperature changes, maintaining its dielectric properties and mechanical performance in outdoor applications.
