NOT INTENDED AS A LUBE FOR PINEWOOD DERBY UNLESS IT SAYS WHITE LUBE ONLY. GRAPHITE IS MUCH BETTER.
Hexagonal Boron Nitride (hBN) is also known as ‘White Graphite’, has similar (hexagonal) crystal structure as of Graphite. This crystal structure provides excellent lubricating properties. hBN is much superior to Graphite and has following characteristics:
•Excellent Lubricating Properties due to low Coefficient of Friction at 0.15 to 0.70
•Good Chemical Inertness
•Thermal Conductor (result: better heat dissipation)
•High Temperature Stability, 1000o C in Air, 1400o C in Vacuum and 1800o C in Inert gas
•Low Thermal Expansion
•Low Dielectric Constant
•High Load bearing properties
•Non-Wetting: hBN is not wetted by Glasses, Salts and (most) metals, therefore it provides strong resistance to chemical attack Easy Machineability (in hot pressed state). Complex shapes can be machined from hot pressed structure.
0.4oz in tube.
How much is that? It’s about a 1/3 cup. At 3 grains per hundred rounds, a reloader should have enough to give you significant data.
