How do I find the PhysicalProperty values for a Material outside of Roblox's pre-existing materials?

I want to know where I can find the PhysicalProperties of real-life materials outside of the ones already provided by Roblox.

I’ve done a bit of research on friction values and all the resources I found only provide the friction values between two different materials, not a Friction and FrictionWeight value for a single material.

Does anyone know if Roblox’s values are based on some sort of material database or if some similar database exists where I can find this information?
