Windbond PF 101L

General Information

Most common phenol-formaldehyde resins for mineral wool production are resols manufactured by condensation of formaldehyde and phenol catalyzed by strong alkalis and using a large molar excess of the formaldehyde.

1. Application of Rockwool Binder

Phenol-formaldehyde resin having a low amount of free formaldehyde, a phenol-formaldehyde resin is used as a binder for mineral wool insulation product.

The mineral wool products have traditionally being manufactured by welding glass fibers by means of phenol-formaldehyde resins, profiting from a relatively low cost and the goodmechanical properties, stability and water resistance granted to the finished products. Most common phenol-formaldehyde resins for minera wool production are resols manufactured by condensation of formaldehyde and phenol catalyzed by strong alkalis and using a large molar excess of the formaldehyde.
