Foam spec sheets are chock-full of information - but admittedly, aren’t the most exciting read. If you’re browsing a spec sheet - like one of the ones available in our technical documents - here are the three key takeaways you need to know.
1. Tests and Requirements
The main data on any spec sheet will be the test properties along with minimums and maximums. This will yield any vital information you’ll need to consider when choosing a foam and designing, such as:
- Density
- Tensile strength
- Elongation
- Tear strength
- Air flow
This section will also include any additional tests done to the material, such as fire resistance and flammability. These are most often noted by the name of the test with a Pass/Fail - for example, UL94HF-1/Pass. You can reference the test maker for specifications - in that example, UL is the test maker and 94HF-1 refers to specific flammability tests applied horizontally and vertically to the material.
If you’re ever unsure what a test means, contact one of our foam packaging experts - we’re always happy to help translate.

2. Industry Specifications and Grades
The next piece of information to look out for on a spec sheet are any industry-specific grades and tests. In this example above, the specification MIL-PRF-26514G indicates that this specific foam meets Military spec requirements.

3. Safety Warnings
Last, but certainly not least, you’ll want to pay attention to any safety warnings in the spec sheet. This section contains important information regarding flammability, toxicity and other key considerations when fabricating foam.
