High purity micronised graphite is a critical ingredient in transformational battery systems and fuel cells, It is used in both the cathode and anode of lead acid batteries. It is also the first stage in producing advanced active anode materials and the CSPG (coated, spheroidised, purified graphite) needed for enhanced charge transfer and cycle stability in lithium-ion and other secondary rechargeable batteries.
Expandable graphite is an essential ingredient in fire retardants, from protective clothing to building materials. Its conductivity makes it a vital contributor to thermal insulation and building safety.
In automotive engineering, graphite is pivotal in both friction materials and composites for engine block seals, composite seals, brake pads, clutch facings, log brake systems, industrial brakes and high-performance brakes. Graphite minimises wear and optimises performance by balancing thermal load with natural lubrication helping to meet stringent performance and safety standards in modern vehicles.
Micronised graphite powders have long been used as a lubricant additive in dispersions for steel making, forging, seamless pipe manufacturing, glass manufacturing and other foundry applications. As a parting agent, graphite streamlines metal fabrication and protects the surface finish of cast components. ASTM Mesh is also used in refractories, while coarse natural flake graphite is used in crucibles.
Due to their low‑friction properties, ASTM mesh flake and micronised graphite are extensively used in lubricants, greases, thread compounds, drilling fluids, graphite dispersions and mould release agents. They are key for specialty lubes used in rail, food manufacturing equipment, antistatic and nuclear grade lubricant applications. In agriculture they are used in seed lubes, seed coating additives and machine grease.
In the coatings industry, high purity micronised graphite is used as a pigment, in conductive coatings, adhesives and thermal paints. It helps form a moisture and corrosion‑resistant barrier on metal surfaces, warding off moisture and chemical attack. Its impressive thermal conductivity makes it ideal for heat‑resistant formulations on industrial equipment and automotive components improving durability.
Micronised graphite enhances plastics and polymers by boosting electrical conductivity and thermal stability while providing natural lubrication. This additive improves not only the processing and durability of components, such as gaskets and sealants, but also delivers reliable performance in high‑temperature, high‑pressure environments. Examples include:
- Automotive: fuel injection systems, anticorrosion systems, fuel tank inlet, electrostatically paintable parts
- Computing: antistatic parts and accessories
- Electronic component handling: carrier boxes, carrier trays, carrier tapes
- Films: antistatic and conductive films, packaging films, garbage bags
- Medical: clean room equipment, antistatic articles
- Other: antistatic flooring, heating elements, sensors, PTC switches, UV protection and pigmentation
- Transport: wheels, containers, bins, pallets
Finely milled graphite plays a vital role in powder metallurgy as both a lubricant and a mould release agent. It enables smoother compaction during the sintering process, resulting in denser, more uniform metal parts with enhanced mechanical strength. The controlled particle size and purity of our graphite ensure consistency and reliability in high‑precision manufacturing, vital for producing components with stringent quality requirements.
Micronised graphite is used in silicon carbide (SiC) manufacturing to inhibit SiC fiber growth, and facilitate machining and lapping accuracy for body armour, SiC optic mirrors, bushings, seals, ceramic ignitors, welding electrodes, semiconductor siliconcarbide crystal catalyst and sintering lubricant.
Graphite’s exceptional heat‑spreading capabilities make it a sought‑after thermal management for geothermal, hot metal toppings and continuous casting applications. In electronic equipment, micronised graphite is used in thermal pastes and expandable graphite is used in heat‑management foils to efficiently dissipate heat and protect critical components. This is vital for maintaining performance and reliability in consumer electronics, power devices and semiconductor systems.
Mixed with clay binders, micronised graphite forms the core of modern “lead” pencils, delivering smooth, consistent writing performance and an ideal balance of darkness and durability.
