what is phenol formaldehyde resin


Phenol formaldehyde resin, or PF resin, is a synthetic thermosetting plastic developed in early 1900s. It is a type of thermosetting plastic, meaning when it is heated and then cooled, it retains its shape. PF resin is commonly used in a variety of industries, from coatings and adhesives to electrical components and moldings.

PF resin is created by polymerization of phenol and formaldehyde in an acidic medium. Phenol is an organic compound, which is derived from coal or petroleum. Formaldehyde is an aqueous gas with a distinctive pungent odor. When combined, two chemicals form a polycondensate known as phenol-formaldehyde resin.

The most important properties of PF resin are its hardness, strength and durability. This material is resistant to heat, water, solvents, and chemical breakdown. In addition, resulting material is an insulator of electricity, meaning it can be used in applications such as electrical equipment and printed circuit boards.

PF resin is used in a variety of products, including insulators, wood glues and adhesives, coatings, laminates, abrasives, and moldings. It is also used in production of cases and furniture, as well as in circuit boards and as a component of electrical appliances. In addition, it is used in production of molded parts, ornaments, and buttons, among other items.

The production of phenol-formaldehyde resin is regulated by U.S. Environmental Protection Agency (EPA). This is to ensure that process does not create hazardous by-products. Furthermore, health risks associated with exposure to chemicals used in process have been reduced, thanks to technological advances and improved engineering.
