Aerotape™ EPDM Foam Tape: Enhancing Insulation and Sealing Solutions


When it comes to insulation and sealing solutions, having a reliable and efficient product is crucial. That’s where Aerotape EPDM Foam Tape, a trademarked brand of flexible self-adhering foam tape by Aeroflex, comes into play. This high-quality foam tape is designed to provide exceptional performance and ensure installation integrity in a variety of applications. Let’s delve deeper into what Aerotape EPDM Foam Tape is, its common uses, variations, technical specifications, and limitations.

What is Aerotape EPDM Foam Tape?

Aerotape EPDM Foam Tape is a flexible self-adhering foam tape that is made from the same high-quality EPDM rubber as AEROFLEX EPDM closed-cell insulation. With its unique composition, Aerotape offers excellent thermal and moisture resistance properties, making it an ideal solution for wrapping hot and cold pipes and sealing glued seams of AEROFLEX EPDM tube, sheet, and roll insulation.

Common Uses of Aerotape EPDM Foam Tape:

Aerotape EPDM Foam Tape finds wide application across various industries, including HVAC, refrigeration, and plumbing. Here are some common uses:

  1. Refrigeration Piping & Equipment: Aerotape is commonly used for insulating refrigeration piping and equipment. It effectively reduces heat gain/loss, prevents condensation, and contributes to energy efficiency, ensuring optimal performance of the refrigeration systems.
  2. Plumbing Piping & Equipment: Plumbing systems can greatly benefit from Aerotape EPDM Foam Tape. By wrapping pipes and equipment, the tape helps in minimizing temperature fluctuations, preventing condensation-related issues, and maintaining the desired temperature of the water or other fluids.
  3. Valve Handles: Another important application of Aerotape is in sealing and insulating valve handles. The tape provides a tight and secure seal, preventing heat transfer and condensation formation, ultimately enhancing the efficiency and longevity of the valves.

Variations of Aerotape EPDM Foam Tape:

Aerotape EPDM Foam Tape is available in a standardized size to cater to various insulation and sealing requirements. It comes in rolls with the following specifications: 2 inches wide, 30 feet long, and ⅛ inch thick. The black color of the tape adds a sleek and professional touch to the installations.

Technical Specifications and Limitations:

To ensure reliability and performance, it’s essential to understand the technical what Aerotape EPDM Foam Tape is capable of:

  1. Service Temperature Range: Aerotape is designed to withstand extreme temperatures, ranging from -70°F to 200°F (-57°C to 93°C). This wide temperature range allows for its use in both hot and cold systems.
  2. Water Vapor Permeability: The tape exhibits a low water vapor permeability of 0.03 Perm·inch. This property helps in preventing moisture infiltration and condensation-related issues, ensuring the integrity of the insulation system.
  3. Water Vapor Absorption: Aerotape has a water vapor absorption rate of 0.3%, indicating its resistance to moisture absorption. This feature is crucial in maintaining the efficiency and longevity of the insulation and sealing applications.
  4. Self-Extinguishing: As per ASTM D 635 standards, Aerotape is self-extinguishing. In the event of a fire, the tape will not contribute to the spread of flames, adding an extra layer of safety to the installations.

While Aerotape EPDM Foam Tape offers exceptional performance in a wide range of applications, it is important to consider its limitations. The tape should not be exposed to direct flame or used as a primary fire barrier


Additional Applications of Aerotape EPDM Foam Tape:

Beyond the common uses mentioned earlier, Aerotape EPDM Foam Tape has proven its versatility in a range of applications. Let’s explore some additional areas where this foam tape can be beneficial:

  1. HVAC Ductwork Insulation: HVAC ducts play a vital role in maintaining comfortable indoor environments. By applying Aerotape to the seams and joints of ductwork, it helps prevent air leaks and ensures efficient airflow. The tape’s insulation properties also aid in reducing energy losses and enhancing overall HVAC system performance.
  2. Soundproofing and Acoustic Insulation: Noise reduction is crucial in various settings, including commercial buildings, recording studios, and residential spaces. Aerotape can be used in conjunction with soundproofing materials to create an effective barrier against noise transmission. Its self-adhering properties make installation quick and hassle-free.
  3. Automotive Applications: The automotive industry relies on efficient insulation and sealing solutions to enhance vehicle performance and passenger comfort. Aerotape can be applied to seal gaps, joints, and seams in automotive components, such as doors, windows, and engine compartments, providing thermal and moisture resistance.
  4. Construction and Building Envelopes: Aerotape is an excellent choice for sealing and insulating gaps and joints in construction applications. It helps improve the energy efficiency of buildings by preventing air infiltration, reducing heat transfer, and minimizing the risk of moisture damage.

Benefits of Choosing Aerotape EPDM Foam Tape:

By opting for Aerotape EPDM Foam Tape, you can enjoy numerous benefits that contribute to the overall effectiveness of insulation and sealing systems:

  1. Enhanced Installation Integrity: Aerotape consists of the same EPDM foam rubber as AEROFLEX EPDM insulation, ensuring compatibility and integrity throughout the installation process. This uniformity helps maintain the desired thermal performance and longevity of the insulation system.
  2. Moisture and Condensation Prevention: With its exceptional moisture resistance properties, Aerotape acts as a vapor barrier, preventing the formation of condensation on cold systems. This feature protects against potential water damage, mold growth, and corrosion.
  3. Energy Efficiency and Thermal Performance: By effectively sealing and insulating pipes, equipment, and building components, Aerotape minimizes heat gain/loss, reducing energy consumption and improving the overall thermal performance of systems.
  4. Compliance with Standards and Regulations: Aerotape meets various industry standards and regulations, including ASHRAE Standard 90.1, IECC, ASHRAE Standard 189.1, California Title 24, CDPH Specification 01350, EPA TSCA Section 6(h), LEED®, REACH, and RoHS. This compliance ensures that the tape meets the necessary requirements for sustainable and environmentally conscious projects.
