It looks like you’re referring to SAGE Graphite 990SP, which is likely a specific grade or type of graphite material. Here’s what I can infer based on industry knowledge:

SAGE Graphite 990SP – Possible Characteristics:
1. Manufacturer: “SAGE” could be a brand or supplier specializing in graphite products (e.g., SAGE Electrochromics, but more likely a graphite producer).
2. Grade (990SP):
– 990 may indicate a high-purity or high-performance grade (e.g., 99.9% carbon content).
– SP could stand for “Special Purpose,” “Sintered Powder,” or “Superfine Particle.”

Typical Applications of High-Purity Graphite:
– Electrodes (EDM, furnace, or battery applications).
– Thermal management (heat sinks, crucibles).
– Semiconductor/Lithium-ion battery components.
– Industrial seals or bearings.

Next Steps:
– Check the technical datasheet from the supplier for exact properties (density, resistivity, particle size, etc.).
– Verify if it’s isotropic (uniform properties) or extruded/molded.
– Confirm intended use (e.g., conductive additive, refractory material).

If you have more context (e.g., application, supplier details), I can refine the answer!
