Hardboard

Kup

Can anyone tell me if hardboard is manufactured like MDF using urea-formaldehyde resin?

This is the only definition I can find:

"Hardboard is a compressed, composite board. Fibre residuals are saturated in a wet process and then compressed to a sheet."

Does it still use glue??

Any advice welcome. Thx.

Hardboard ( high density fibreboard)
This product was discovered accidentally when a steam valve failed in a laboratory, causing high, prolonged pressure on a fibre mat, which produced a hard dense panel. Hardboard is often called Masonite, named after the scientist William Mason who was running the experiment and was out having lunch when the incident occurred.
