Material specifications and capabilities for Airpop® and Airehide®, how do they compare?


Frequently asked questions. As an industry leader, we feel it is important to share our expertise as well as continue to educate and inform others of Plymouth Foam’s materials and capabilities. For this reason, we have started this question and answer series.




Airpop® is made with 98%, engineered air, and can be fabricated or molded precisely to any specified shape. Because AirPop® is lightweight, it can easily be transported and has an excellent price to performance ratio.


Airpop®  Properties


  • Customization: Custom molds ensure that products fit snugly
  • Reduced Costs: Long-term benefits of constant R-value are exactly what makes Airpop® the primary material of choice for economical and reliable performance
  • Sustainability: Airpop® reduces CO2 emissions and is 100% recyclable
  • Noise Reduction: Fabricated materials insulate or isolate the responsible components to eliminate annoying noise
  • Protection: Shock & vibration protection, in the small parcel shipping environment, and in other distribution cycles, has been one of the most often used applications for foam packaging, whether shape-molded or fabricated.


Airpop® Industry Applications


  • Food & Beverage/Food Service & Pharmaceutical
  • OEM
  • Building Systems & Plumbing
  • Automotive/Transportation & Recreational Vehicles
  • Appliances & Consumer Packaging


The air technology (interior) combined with the protective, rugged and durable hide (exterior) provides unique product solutions. We share specific specifications and capabilites, below.


Airehide®  Properties


  • Vibration Dampening: Good vibration dampening and even isolation can be readily achieved with Airehide™ materials.
  • Chemical Resistant Properties: Very good chemical resistance overall, particularity against acids and alkalines, solvents, grease, oil, etc.
  • Ultraviolet Radiation Resistance: Good UV resistance for most applications. Long-term exposure primarily affects surface color while some embrittlement, chalking and crazing can occur depending on exposure levels and durations.
  • Humidity and Water Resistance: Good resistance to humidity and water exposure. Typical water absorption, density dependent, is 0.1% to 0.3% by volume after 24 hours submersion and 0.6% after 1 week.

Airehide® Applications

The strength and lightweight properties fill the needs of a wide array of applications which can drive industry growth. Due to their ability to absorb massive impacts, these below materials are ideal for:


  • HVAC Enclosures (EPP)
  • Impact Protection (EPP)
  • Travel and Storage Protection (EPP)
  • Totes and Returnable Packaging (EPP)
  • Structure and Buoyancy (EPE)
  • Impact and Resilience (ETPU / ETPO)
  • Cushioning (xEPE)
