How to Spec a Missile or UAV Hardware Material: What to Send H-O for a Quote
The fastest way to a useful quote for missile or UAV hardware materials is to name the job and the environment, not just ask for a material. These compact platforms combine thermal, shock, and sealing jobs in a small space, and the family depends on which job the part does and what it sees. Here is the short list of facts that move a request from vague to manufacturable, and what our engineering team does with each one. H-O supplies materials only; the system design stays with you.

The nine facts to send, and what each one decides
Missile and UAV hardware concentrates thermal, shock, and sealing jobs in a small space, so a useful quote starts with which job the part does and the environment around it. The nine facts below are what our applications engineering team needs to recommend a family and convert it accurately. H-O supplies materials only; the system design stays with you. Send what you have and we will flag what is open.
- The job the part does. Thermal insulation, thermal interface to a sink, shock cushioning, or aperture sealing. These point at entirely different families, and many compact parts combine two.
- The zone and its environment. Where the part lives and what it sees: temperature range, fuels or chemicals, moisture, and whether the bay is sealed or vented.
- For a thermal-interface part, the heat and the gap. The component footprint and the gap to the heat sink, since these decide between a thin graphite spreader and a conformable gap filler.
- For a cushion, the mass and the crush space. The supported mass and the thickness available to crush, plus whether the input is a single transient or repeated, which set the grade and rebound behavior.
- Outgassing requirement. Whether the location calls for low-outgassing materials, in which case we steer toward grades whose TDS reports ASTM E595 screening.
- Fire and flammability requirement. Any FAR 25.856 insulation context or UL 94 class your program expects on the TDS.
- Geometry. A drawing or DXF is ideal; a dimensioned sketch starts a quote; an existing part we can measure works too.
- Attachment. Pressure-sensitive adhesive, mechanical capture, or a laminated assembly, and any liner preference.
- Documentation and quantities. The data package your program expects, plus sample needs, estimated annual usage, and kit or shipset structure.
From Request to Converted Part
| What you send | What it decides |
|---|---|
| Job + zone/environment | The family and whether outgassing or fire rules apply |
| Heat and gap (TIM) or mass and crush (cushion) | Spreader vs gap filler; cushion grade and thickness |
| Outgassing requirement | ASTM E595-screened grades for sealed or high-altitude bays |
| Fire requirement | FAR 25.856 context and UL 94 class on the TDS |
| Geometry, attachment, quantities | The converting method and the kit structure |
Qualitative guidance only; confirm grades on their current technical data sheets. H-O supplies materials and does not design or test weapons hardware.
What engineering does with the list
With the job and environment defined, we shortlist a family: graphite spreaders or boron-nitride pads for thermal-interface duty, PORON and ShockSeal for cushioning, SOLIMIDE or aerogel for insulation, and silicone or fluorosilicone for aperture sealing. The environment confirms the family, the outgassing and fire requirements filter the grade, and the geometry and attachment set the converting method. The output is a family-and-grade direction plus a converted-part quote, never a system design.
What happens after you send it
We confirm the family-and-grade direction and the converting approach, quote the converted part to your drawing, and flag open questions, such as a missing crush space or an undefined outgassing requirement. For common configurations on materials we keep on hand, samples typically ship in three to five business days; standard production runs about two weeks after drawing approval, with expedited service available. Every order carries the maker's TDS for the grade and lot under our ISO 9001:2015 certified quality management system.
The mistakes this checklist prevents
The list heads off the costly failures. Without the gap dimension, a thermal pad can be specified that does not bridge to the sink. Without the crush space, a cushion can be quoted that bottoms out under the event. Without the outgassing requirement, a grade can be chosen that contaminates sealed optics. And without the fire requirement, a mechanically ideal material can be removed at documentation review. Nine facts up front replace several rounds of revision.
Frequently asked questions
What is the most important thing to tell H-O about a missile or UAV material?
The job the part does, thermal insulation, thermal interface, shock cushioning, or aperture sealing, and the environment around it. Those two facts decide the family and flag whether outgassing or fire requirements apply. Add the heat and gap for a thermal part, or the mass and crush space for a cushion, and we can point at a grade quickly.
Do I need a full drawing, or is a sketch enough?
A drawing or DXF is ideal, but a dimensioned sketch starts a quote, and we can measure an existing part to reverse-engineer it. What we need early is the job, the environment, and the key dimensions (component footprint and gap for a thermal part, mass and crush for a cushion), since those define the part before geometry is final.
What about outgassing for sealed optics or high-altitude bays?
Tell us if the location is sensitive to outgassing, and we will steer toward grades whose technical data sheet reports ASTM E595 screening (total mass loss and collected volatile condensable material). The screening data lives on the maker's TDS; H-O does not run the test, but we will select and convert from grades that carry it.
What quality documentation does H-O provide for defense programs?
The maker's technical data sheet for the exact grade supplied and lot-coded traceability under our ISO 9001:2015 certified quality management system. Tell us what your program expects on the order so the package matches. H-O supplies converted materials and their documentation; we hold no claim to program-specific certifications and make no qualification or compliance determinations.
Does H-O design missile or weapons-system components?
No. H-O Products is a materials converter. We die-cut, waterjet, laminate, and kit thermal, shock, and sealing materials to your drawing and supply the maker's published data; we do not design, integrate, analyze, or test weapons systems, and we make no statement about any system's performance. Program design and certification remain entirely with you.
