Phenolic resin is a kind of thermosetting polymer formed by polycondensation of phenol and formaldehyde. It features high heat resistance, chemical resistance, electrical insulation, mechanical strength, flame retardancy and low cost. After curing, it forms a stable cross‑linked structure and is widely used in molding compounds, coatings, adhesives and refractory materials.
