Elastomeric foam is a versatile material widely employed in various applications, particularly in packaging. One of the goals at Worldwide Foam is to present and discuss the characteristics of elastomeric foam, highlighting its insulating properties and its essential role in packaging. Therefore, we are excited to bring you the following blog.


In the upcoming paragraphs, our focus will be on the insulating characteristics of elastomeric foam and its significance in the realm of packaging. Keep reading to discover all the details.

Insulating characteristics of elastomeric foam

Elastomeric foam, also known as EPDM foam, is inherently insulating due to its composition of closed cells. The air trapped within these cells acts as a barrier, preventing the transfer of heat or cold from the external environment to the interior of the foam.


EPDM foam exhibits high resistance to heat flow, making it exceptionally effective at impeding the movement of heat. This quality makes it an ideal choice for applications requiring protection against temperature fluctuations.


Additionally, elastomeric foam serves as a reliable acoustic insulator, thanks to its unique construction. The closed cells of EPDM foam obstruct the transmission of sound, showcasing its versatility beyond packaging and highlighting its diverse range of applications.


Moreover, elastomeric foam is frequently employed in scenarios demanding noise reduction, such as in electronics packaging or building insulation.

Types of elastomeric foam for packaging

There are four main types of elastomeric foam commonly utilized in packaging.

Neoprene foam

Neoprene, a synthetic elastomeric foam, is distinguished by its resistance to abrasion, water, and chemicals. It is frequently employed in packaging to safeguard products from moisture or potential mechanical damage.

PVC foam

PVC, a thermoplastic elastomeric foam, is known for its resistance to moisture, chemicals, and temperature. It is a popular choice for packaging items that require protection from moisture or temperature fluctuations.

Nitrile foam

Nitrile, a synthetic elastomeric foam, stands out for its resistance to abrasion, oil, and chemicals. Its common application in packaging is to shield products from abrasion or exposure to various chemicals.

EPDM foam

EPDM, a thermoplastic elastomeric foam, is recognized for its resistance to weathering, chemicals, and temperature. It is often employed in packaging to protect products from the elements.


Understanding the unique properties of each type of elastomeric foam allows for tailored solutions in packaging, ensuring effective protection against specific environmental factors.

Advantages of elastomeric foam in packaging

Elastomeric foam presents numerous advantages in packaging, including:

  • Excellent insulating properties: Elastomeric foam serves as an exceptional insulator against heat, cold, moisture, and vibration. This quality makes it an ideal choice for safeguarding products from potential damage caused by these elements.

  • Resistance to mechanical damage: Elastomeric foam demonstrates resilience against abrasion, impact, and puncture. This characteristic makes it well-suited for protecting products from mechanical damage during transportation and handling.

  • Good chemical resistance: Elastomeric foam exhibits resistance to a wide range of chemicals, making it a suitable option for packaging products that may come into contact with various chemicals.

Now that you are familiar with the insulating properties of EPDM foam, or elastomeric foam, you can make more informed decisions regarding its application.
