Phenol-formaldehyde resins (PF)

Phenol-formaldehyde resins (PF)

Phenol-formaldehyde (PF) resins are synthetic polymers made by reacting phenol with formaldehyde. They are one of the earliest synthetic resins, widely known for their high mechanical strength, heat resistance, and chemical stability. PF resins are used extensively in producing molded products, adhesives, coatings, and laminates. Their applications include electrical insulation, wood products (like plywood and particleboard), and automotive components. The material is often thermosetting, which hardens irreversibly when heated, making it durable and resistant to wear.
