Consistent-Reactivity Phenol For Rock Wool Phenolic Resin Adhesive. Pure phenol is a colorless or white crystalline solid at room temperature that may turn pale pink after long exposure to air and light. We use sealed packaging to guarantee stable quality during long sea transportation, fully meeting continuous production demands of thermal insulation material manufacturers.
Our phenol with purity exceeding 99.1% is acicular crystal solid rather than powder. It melts into clear liquid when temperature exceeds 40.5℃. Packaged in 200kg iron drums for bulk export, it serves as the key raw material for producing phenolic adhesive for rock wool board, perfectly matched with paraformaldehyde.
The synthesized phenolic adhesive tightly bonds basalt fiber, improving tensile strength, layering resistance, and fire performance of thermal insulation boards. This represents our most mainstream application for insulation manufacturing factories.
