What is formaldehyde resin?
Resin is essentially a glue typically used in commercial processes. For example a resin is used as the adhesive (glue/resin) that holds the saw dust together to make particle board. Formaldehyde resin is any resin that uses formaldehyde in production of the resin. Turns out that formaldehyde resins are cheap and very good and therefore widely used. Unfortunately, the formaldehyde off-gasses forever and is commonly at high enough concentrations to be a health risk. The State of CA has lowered their recommended concentration of formaldehyde to avoid cancer risks to just 7 ppb (parts per billion). This is actually difficult to achieve and 98% of the CA homes tested exceeded this 7 ppb concentration. The typical home was 27 ppb or four times higher than recommended. Unfortunately, homes especially those that are energy efficient have even higher concentrations of formaldehyde. 100 to 200 ppb is not uncommon.
