Advantages of Insulation EPDM Foam

Moisture resistance
EPDM’s chemical polarity and water vapor permeability in particular means that additional water vapor barriers will only be needed in extreme circumstances, such as high ambient temperature, high humidity and below-ambient service temperatures. This level of permeability rivals the permeability of cellular glass insulation.
Weather resistance
As a non-polar insulation, EPDM’s saturated chemical structure can withstand ultraviolet light and ozone for longer periods than its polar NBR/PVC counterpart and is widely considered to be more resilient and long-lasting than NBR/PVC insulation. NBR/PVC-based insulation will often require additional UV protection for exterior applications, such as acrylic resin coatings, which must be periodically re-applied depending on the UV intensity it is subjected to.


Thermal conductivity
EPDM insulation and NBR/PVC have similar thermal conductivity levels. They both manage a continuous low service temperature of -297 degrees F, however, EPDM’s continuous high service temperature of 257 degrees F is slightly higher than NBR/PVC’s 220 degrees F.
Flame and smoke properties
EPDM insulation and NBR/PVC both meet the industry standard ASTM E 84 25/50 flame spread/smoke-developed index and NFPA 90A and NFPA 90B to insulate pipes and ducts in plenum-rated applications.

Properties of Insulation EPDM Foam
Resilience: EPDM foam exhibits remarkable resilience, allowing it to compress and rebound repeatedly without losing its original shape or mechanical properties. This resilience makes it ideal for applications requiring cushioning or shock absorption, such as in automotive seating, gaskets, and insulation pads.
Weather Resistance: EPDM foam is inherently resistant to weathering, UV radiation, and ozone exposure, making it suitable for outdoor applications where prolonged exposure to harsh environmental conditions is expected. This weather resistance ensures long-term durability and performance in applications such as window seals, roofing membranes, and outdoor gaskets.
Thermal Insulation: The closed-cell structure of EPDM foam provides effective thermal insulation properties, helping to reduce heat transfer and energy loss. This makes EPDM foam suitable for insulating HVAC systems, refrigeration units, and building envelopes, contributing to energy efficiency and cost savings.
Chemical Resistance: EPDM foam is resistant to a wide range of chemicals, including acids, alkalis, and solvents, making it suitable for applications where exposure to chemical substances is a concern. This chemical resistance enhances the durability and longevity of EPDM foam in industrial settings, such as sealing gaskets in chemical processing equipment or lining for storage tanks.
