PHENOLIC UREA Meaning and
Definition
-
Phenolic urea is a type of resin that combines the characteristics and properties of phenol formaldehyde and urea formaldehyde resins. It is a thermosetting synthetic material that is widely utilized in various industrial applications, especially in the production of wood-based composite materials.
Phenolic urea resins are formed through a condensation reaction between phenol and urea compounds with formaldehyde. The resulting resin possesses excellent heat resistance, dimensional stability, and mechanical strength. These properties make it a suitable choice for manufacturing products that require excellent performance under high-temperature conditions.
One of the prominent applications of phenolic urea resin is in the production of plywood and particleboard. The resin is used as an adhesive to bind the wood fibers or particles together, enhancing the overall structural integrity and durability of the composite material. Additionally, its resistance to moisture absorption and fungal attack further enhance its suitability for these applications.
Another application of phenolic urea resin is in the production of molded articles, such as electrical fittings, automotive parts, and kitchenware. The resin's heat resistance and dimensional stability make it a preferred choice for these applications where high temperatures and mechanical stress may be encountered.
In summary, phenolic urea is a thermosetting resin that combines properties of phenol formaldehyde and urea formaldehyde resins, offering excellent heat resistance, dimensional stability, and mechanical strength. It finds extensive use in the production of wood-based composites, such as plywood and particleboard, as well as in molded articles for various industrial applications.

Etymology of PHENOLIC UREA
The word "phenolic urea" is a composite term that combines two separate chemical compounds: "phenolic" and "urea". Here is the etymology of each component:
1. Phenolic:
- The word "phenolic" is derived from the root word "phenol".
- Phenol originated from the French word "phénol", which was coined in the mid-19th century by French chemist Auguste Laurent.
- Laurent derived the term from "phenic", an old-fashioned name for carbolic acid, which is a type of phenol.
- The root "phenic" came from the Greek word "phenos", meaning "to show", referring to its characteristic of giving color reactions.
- Thus, "phenol" was used to describe a class of organic compounds with a hydroxyl (OH) group attached to an aromatic ring.
