Designed for demanding environments, Goodfellow's Platinum Foil offers exceptional chemical stability, thermal resilience, and biocompatibility - making it ideal for electronics, aerospace, medical implants, and scientific instrumentation. Manufactured from 99.85% to 99.999% pure platinum with ultra-tight thickness ranges (0.0005 mm to 2 mm), it integrates seamlessly into precision assemblies where purity, durability, and repeatability are critical. Available in lengths and widths up to 150 mm with optional polishing and polyester support. Platinum’s exceptional chemical inertness ensures corrosion resistance in hot acids and oxidizing environments, while its high melting point and low vapor pressure support stable performance under extreme temperature changes and vacuum conditions. Its high density enables robust ultra-thin foil components, and its catalytic activity and biocompatibility make it the material of choice for electrodes, sensors, and implantable devices. Combined with reliable thermal conductivity and formability, these properties make our platinum foil indispensable in high-tech applications from fuel cells to neural interfaces.

Key Features

Platinum foil possesses a combination of material characteristics that make it particularly well suited for electronics, aerospace, medical implants, catalysis, and scientific instrumentation:


Exceptional Chemical Inertness

Platinum is one of the most chemically inert metals, resisting oxidation and corrosion in aggressive conditions. It only dissolves in aqua regia, ensuring unmatched longevity in harsh chemical applications.


High Melting Point (1,768 °C)

With one of the highest melting points among precious metals, platinum remains structurally stable under extreme temperature changes, making it ideal for furnace linings, high-temperature gaskets, and thermal shielding.


High Density (21.45 g/cm³)

Its high density contributes to robustness and structural stability, even in ultra-thin gauges. This is critical for precision foil gaskets, shims, and components in MEMS and microelectronics.


Catalytic Activity

Platinum is renowned for its catalytic performance, accelerating oxidation, hydrogenation, and reforming reactions without degradation. It is widely used in chemical reactors, fuel cells, and laboratory catalytic studies.


Thermal Conductivity (72 W/m·K)

Platinum offers good thermal conductivity, enabling efficient heat spreading in thin foil heating elements and thermal management films. This supports uniform temperature control in sensors and precision tooling.


Biocompatibility

Naturally bioinert and non-toxic, platinum foil is used in medical implants, pacemaker leads, neural electrodes, and biosensors. Its chemical stability ensures safe, long-term contact with biological tissues.


Workability & Formability

Platinum foil can be cold-worked and annealed without compromising its durability, making it ideal for custom shaping, microfabrication, and precision foil components.


Low Vapour Pressure & Vacuum Stability

Platinum maintains extremely low vapour pressure even at elevated temperatures, preventing outgassing in vacuum environments. This is ideal for UHV seals, deposition shutter blades, and vacuum chamber liners.


Optical Reflectivity & Emissivity Control

Platinum foil offers reliable light reflection across the visible and near-infrared range, along with a stable heat emission profile. These properties are critical for black-body calibration targets, radiometric heat-flux sensors, and optical pyrometer calibration.

Industrial Applications

High-purity platinum foil is used across high-technology sectors for its unparalleled chemical inertness, catalytic activity, thermal stability, and biocompatibility:

Catalysts & Chemical Processing
Platinum foil acts as a catalyst and support in hydrogenation, reforming, and emission control — including fuel cells and petroleum refining — owing to its surface activity, resistance to poisoning, and durability in hot, corrosive environments.
Electronics & Sensor Engineering
Its corrosion resistance and thermal stability enable platinum foil to deliver low-drift, high-reliability performance in RTDs, heating circuits, and microelectronic contacts.
Aerospace & Thermal Management
Used in gaskets, thermal shielding films, jet engines, re-entry vehicles, and insulation for spacecraft, platinum foil withstands extreme heat and oxidation without degradation.
Scientific Instrumentation & Laboratory Equipment
Platinum foil ensures chemical purity and dimensional stability in vacuum seals, X-ray windows, pressure sensors, crucibles, and evaporation boats.
Medical & Bioelectronic Devices
Biocompatible and non-toxic, platinum foil is ideal for implantable electrodes, neural interfaces, and biosensors requiring long-term tissue contact.
Glass Manufacturing
Its non-reactivity with silicates and high-temperature durability make platinum foil essential in bushings, stirrers, and feeders for molten glass handling.

Mentions in Scientific Literature

Goodfellow's platinum foil features prominently in research including but not exclusive to domains such as: Advanced Coating & Surface Treatments, used as a substrate for applying ultra-thin diamond coatings in medical implants, and for growing advanced materials like graphene and boron nitride in next-generation electronics [1–4] . Energy Technology Components, serving as a current collector in experimental supercapacitors made from flexible materials, and as a stable reference in X-ray studies to improve fuel cell catalyst performance [5–6] . Medical Implants & Neurotechnology, serving as a core electrode material in implantable neural devices and used to test and fine-tune electrical stimulation techniques in neuroscience research [7] . Nuclear Physics & Particle Detection, used as a substrate for radioactive sources in high-precision experiments including those that study particle behaviour and nuclear properties [8–9] . Electrochemical Sensors & Lab Equipment, used in reference electrodes for chemical sensing and in layered sensor designs requiring precise spacing and stable electrical performance [10] . High-Temperature Lab Processes, used as crucible liners to prevent unwanted reactions during high-temperature nanomaterial synthesis, and applied in thermocouple wires for precise temperature monitoring in demanding lab environments [11] .

Across these disciplines researchers have utilised our platinum foils as electrode substrates and diamond coating supports for medical implants and neural devices [1–3] , current collectors and catalytic reference materials in energy technology [5–6] , ion implantation targets for nuclear calibration sources [8–9] , and precision crucible liners and thermocouple supports in high-temperature nanomaterial synthesis [11] — applications that all benefit from platinum's chemical inertness, thermal resilience, and biocompatibility.
