Product Overview · GrafGuard® expandable graphite flake is a specifically engineered intumescent material used as a fire-retardant additive in · plastics, foams, putties, and coatings. Upon exposure to high temperatures, the material expands and forms a graphite · char that is more resistant to degradation than the carbon chars formed from typical chemical intumescent materials · GrafGuard materials contain no halogenated fire-retardant additives and are manufactured without the lead or chromium · that can be found in some other expandable graphite flakes. With the addition of synergistic chem

Raw and semi-finished materials — alloys, metal powders for additive manufacturing, composites, adhesives, graphite, thermal control coatings.
Used in: Structures, thermal management, propulsion components, additive-manufactured parts.
What changes for space and defence: This is where ECSS outgassing limits bite. A material releasing volatiles in vacuum will condense on the coldest nearby surface, which is usually an optic or a radiator. Ask for TML and CVCM figures and a batch certificate.
What actually decides the purchase: Alloy or grade designation · form and dimensions · mechanical properties · thermal properties · outgassing TML/CVCM · batch traceability
Reference information about materials and feedstock in general — written by us, not a claim by the supplier.
ISO 14001 — Increasingly required by large primes as a supply-chain condition. Not a technical quality indicator. more
ISO 9001 — A floor, not a qualification. It says the company follows its own written process — it says nothing about whether that process is good enough for flight hardware. For space work, look for AS9100D on top of it. more
★ marks standards that matter specifically for flight hardware. Company-level claims, as published by the supplier and unverified — not necessarily specific to this part.
