Rigid, Flexible, and Anti-Static Packaging Foam Built to MIL-PRF-26514
Military Packaging supplies polyurethane foam built to MIL-PRF-26514, the military specification for rigid and flexible packaging foam. Used for cushioning and blocking and bracing, this prefoamed polyurethane protects defense and aerospace hardware from shock and impact through handling, shipping, and storage. We supply it in the types, classes, and grades your program requires, cut and fabricated to your equipment. Order foam on its own or built into a complete mil-spec packaging system we design around your load.
MIL-PRF-26514 is the military specification for polyurethane foam, rigid or flexible, for packaging. It covers prefoamed polyurethane used as cushioning and as blocking and bracing, protecting equipment from the shock and impact of handling, shipping, and storage.
The specification sorts the foam by type, class, and grade, so a callout tells you exactly what material a program requires, from standard flexible cushioning to rigid blocking and anti-static foam for electronics. It also sets the performance the foam must meet, including non-corrosive and flame-resistant properties.
We supply MIL-PRF-26514 foam in rolls, sheets, and fabricated shapes, cut and routed to your equipment. When a drawing calls for MIL-PRF-26514, this is the foam it means.
Every MIL-PRF-26514 foam we supply protects equipment to a tested standard:
The specification defines what makes a compliant packaging foam:
MIL-PRF-26514 organizes foam by type, class, and grade. Type I is standard polyurethane and Type III is anti-static foam for electronics. Within each, Class 1 is rigid and Class 2 is flexible, and the grade sets the foam’s properties and its color, so a callout like Type I, Class 2, Grade C names a specific, known material.
The grades are color-coded, so a Type I standard foam comes in blue, green, or charcoal, and a Type III anti-static foam in yellow, red, or brown. We help you read the callout and supply the exact type, class, and grade your drawing requires, or recommend one when the choice is open.
MIL-PRF-26514 foam protects the hardware across a defense shipment:
MIL-PRF-26514 foam cushions the equipment these sectors ship and store every day:
A few factors point you to the right MIL-PRF-26514 foam. Weigh these, or send us the part and we will recommend one:
MIL-PRF-26514 foam is the interior that holds and cushions the part. It cradles the equipment, fills the space around it, and braces it against the walls of the box or crate, transferring shock away from the hardware. The container carries the load from there.
Sourced as one system, the foam is matched to the part it protects and the box it fits, so a sensitive component rides cushioned and immobilized from the moment you pack it to the moment it is opened.
Polyurethane foam protects by absorbing energy. When a package is dropped or vibrated, the foam compresses and spreads the force over time and area instead of letting it hit the part all at once. The right grade, matched to the weight and fragility of the equipment, keeps that force below the level that would cause damage.
Rigid and flexible grades do different jobs. Flexible foam cushions and conforms around a part, while rigid foam holds and braces a heavier load in place. We select the grade so the foam both cushions the equipment and keeps it from shifting.
The class sets what the foam does. Class 1 rigid foam is firm and structural, which suits blocking and bracing that must hold a heavy part fixed in place. Class 2 flexible foam is softer and resilient, which suits cushioning that absorbs shock and conforms around a delicate part.
Many packages use both, rigid foam to brace the load and flexible foam to cushion the surfaces. We match the class to the job, so the part is held secure and protected at the same time. Tell us the weight and fragility, and we will specify the right class.
Static discharge is a hidden threat to electronics, and standard foam can generate a charge. MIL-PRF-26514 answers with Type III anti-static foam, which dissipates static safely, so a board or module is protected from the spark you cannot feel as well as the shock you can.
For static-sensitive parts, we cut the anti-static foam into the same custom insert that cushions the equipment, so one interior handles both shock and static. Tell us the part and we will supply the Type III foam to protect it.
Reading a foam callout and cutting the right insert is what we do. Our team helps buyers and packaging engineers match the MIL-PRF-26514 type, class, and grade to the part, and meet the cushioning spec that governs the shipment.
Send us the equipment or a drawing, its weight and fragility, and any spec callouts, and we will design the foam, recommend the grade, and quote it, so your hardware ships cushioned and compliant from the first unit.
Every program defines its cushioning a little differently, and we build to yours. When your documentation names a MIL-PRF-26514 type, class, and grade, we match it exactly. When the choice is open, we recommend the foam that fits the weight, the fragility, and the conditions.
That flexibility means your packaging satisfies the spec and protects the part in practice, with no gap between the two.
MIL-PRF-26514 foam does its best work as part of a full system. We cut the foam to your part, seal it in a barrier bag with a desiccant where moisture is a concern, wrap sensitive surfaces, and enclose the pack in a box or crate rated for the journey. Sourced together, the foam cushions and braces the part while every other layer does its job around it.
We supply foam that meets MIL-PRF-26514 for the material, and we build it into packaging that satisfies your spec. Where your drawing cites a type, class, and grade or a cushioning method under MIL-STD-2073, we match it.
Where the drawing leaves a choice, we recommend the foam that best protects your part. Either way, you get cushioning you can ship on.
Tell us the equipment you need to protect, its weight and fragility, the container it ships in, and any spec callouts, and we will cut the foam and recommend the grade.
We supply MIL-PRF-26514 foam in rolls, sheets, and fabricated inserts, on its own or as part of a complete packaging system, with availability and turnaround confirmed in your quote.
We cut MIL-PRF-26514 foam to your equipment and match the type, class, and grade to the job, instead of forcing a generic pad to work.
That combination keeps hardware cushioned, loads braced, and electronics protected after handling, shipping, and long storage.
MIL-PRF-26514 is the military specification for polyurethane foam, rigid or flexible, for packaging. It covers prefoamed foam used as cushioning and as blocking and bracing to protect equipment from shock and impact, in standard and anti-static types.
Type I is standard foam and Type III is anti-static. Class 1 is rigid and Class 2 is flexible. The grade sets the foam’s properties and color. A callout like Type I, Class 2, Grade C names a specific material, in this case standard, flexible, charcoal foam.
Class 1 rigid foam is firm and structural, which suits blocking and bracing that holds a load in place. Class 2 flexible foam is softer and resilient, which suits cushioning that absorbs shock. Many packages use both, and we match the class to the job.
Yes. Type III is anti-static foam that dissipates static safely, protecting boards, modules, and other sensitive electronics from discharge as well as shock. We cut it into the same custom insert that cushions the part.
Yes. The specification requires non-corrosive, flame-resistant material, so the foam sits safely against metals and finishes and meets the fire performance defense programs require. We supply foam that meets those requirements.
Yes. MIL-P-26514 was the older designation for the same polyurethane foam specification, now MIL-PRF-26514. If your drawing still calls out MIL-P-26514, we supply the current MIL-PRF-26514 foam to meet it.
Tell us the equipment you need to protect and its weight and fragility, and we will recommend the right MIL-PRF-26514 foam, then get you a quote.
