Standard structural cores
Start with the SC series for general composite sandwich cores where the process cycle matches the grade.
Grade index
PMI Foam Grades
The table lists the grade series and designations that appear in the manufacturer's public product pages. It does not publish density, mechanical properties or sheet sizes: those values are confirmed from the current TDS.
No TDS is published on this site yet.
Designations are product names. A number in a designation is not a statement of density or performance. Request the current TDS for the grade you are evaluating.
| Series | Published grade designations | Type | Technical data |
|---|---|---|---|
| SC series | SC-50, SC-60, SC-75, SC-100 | Standard | Available on request |
| MSC series | MSC-50, MSC-60, MSC-75, MSC-100 | Heat-resistant | Available on request |
| BA series | BA-26; additional low-density designations to be confirmed | Ultra-low density | Available on request |
| MBA series | MBA-26 | Heat-resistant, ultra-low density | Available on request |
| Moss sheet / thin sheet | Cut sheet; designations to be confirmed | Thin sheet | Available on request |
| Buoyancy grades | Designations to be confirmed | Buoyancy | Available on request |
Sheet sizes, thickness ranges, tolerances, packaging and minimum order quantities are also confirmed per inquiry.

Technical data and TDS
No TDS is hosted on this site. For the grade you are evaluating, request the current datasheet and tell us which properties matter for your design. We will confirm what can be provided.
A complete TDS should let you check:
- Density and the applicable range
- Compressive and shear strength and modulus
- Test methods and units
- Thermal limits and recommended processing window
- Sheet sizes, thickness range and tolerances
- Whether values are typical or guaranteed

How to choose a starting series
Heat-resistant cores
The MSC series is the heat-resistant counterpart. Confirm the cure cycle and allowed limits before selection.
Low-density and thin cores
The BA and MBA series cover low-density options, while moss sheet covers thin cut sheet. Availability is confirmed per inquiry.
Questions
Grade and data FAQ
Why are density values not listed in the table?
The manufacturer's public pages contain inconsistent density ranges, and no TDS has been confirmed for publication. We only publish values that have been confirmed in writing, so the table lists designations and series only.
Are the numbers in a grade name the density?
No. The numbers are part of the product designation, not a published specification. Density, strength, modulus and temperature limits must come from the current TDS for that grade.
Which grades can I order?
Availability is confirmed per inquiry. Send the series or designation, application, thickness, sheet size and quantity, and we will confirm what can be supplied.
Do you provide a TDS?
Request the current TDS for the grade you are evaluating. We will confirm whether it can be shared for that grade.
Are the test reports downloadable?
No. Third-party test reports are not published for download. Availability and permission to share them are confirmed per inquiry.
Do you supply both standard and heat-resistant types?
The published series include standard and heat-resistant designations. Actual availability for a given grade is confirmed per inquiry.

Send the designation or series, application, thickness, sheet size and quantity. We will confirm availability and the data we can share.
