Exceptionally low thermal conductivity — maintains structural integrity under extreme temperature gradients in aerospace environments.
Naturally resistant to fire and high temperatures, creating a sturdy char layer that protects the inner material during ablation.
Extraordinary lightness from the high gaseous content of each microscopic cell — critical for launch vehicle weight budgets.
Compressible and resilient cellular structure acts as a cushion, absorbing mechanical shocks and vibration loads during launch.
Impermeable to liquids and gases, ensuring protection of sensitive cryogenic tanks and structural joints from contamination.
Sourced from the cork oak's bark — a fully renewable, reusable and recyclable raw material harvested without harming the tree.
Precision
Pre-formed to match your exact fairing profile, Molded P50 eliminates the time-consuming fitting and trimming required with flat sheet materials. The result is a seamless, ready-to-bond thermal protection shell that reduces labor, minimizes waste, and ensures consistent coverage across curved and conical surfaces.
Available in custom geometries to match your specific launch vehicle requirements.
Where It's Used
Frustum and forward skirt joints protected from extreme aerodynamic heating during ascent phase.
Thermal insulation at critical structural joints of solid rocket boosters to prevent heat transfer.
3D-shaped P50 applied directly to the fairing geometry reducing labor and application time.
Thermal insulation protecting cryogenic propellant tanks from external heat sources and condensation.
Covers protecting umbilical connections and ring structures during launch and early flight phases.
Impact protection from pyrotechnic solutions and debris mitigation across several launch systems.
