Phenolic resins, the valuable property of which is the ability to be converted into durable coke in high yields during pyrolysis, are among the most heat resistant organic polymers. That is why Phenolic resins are so widely used in abrasion, friction and other materials, which are exposed to intensive thermal loads during their exploitation.

Phenolic resins have found widespread use in foundries In the last 5 years, the increase in demand for phenolic resins has been caused not by the expansion of the foundry business, but by various innovations in technological processes and, in particular, by the use of new types of binders.
It is also recycled only to extract the phenol it contains. Phenolic resin reinforcements are used in the manufacture of soles and heels for shoes, as well as in the manufacture of solid pneumatic tyres. They give the products increased hardness, stiffness (which is retained even at elevated temperatures) and wear resistance, but reduce elasticity.he second biggest consumer of benzene is phenol synthesis. The second biggest consumer of benzene is phenol synthesis. Phenol is one of the oldest benzene derivatives.Several methods are known to obtain phenol from benzene.
The newest of them is phenol production through cumene and cumene hydroperoxide. Further growth of phenol synthesis capacity comes only from application of this process. In this process, benzene is first alkylated with propylene to produce cumene. Cumene is then oxidised to hydroperoxide, which is decomposed to phenol as a by-product to produce acetone. The biggest consumer of phenol is the production of thermosetting resins, which are processed mainly into moulding compositions. One of the most promising applications for phenolic resins is the production of phenolic adhesives, whose consumption in the plywood industry is steadily increasing.
