The phenolic sheet resin is created by combining aldehyde and phenol. When these organic compounds are mixed together and both heat and pressure are applied, it can cause polymerization. Polymerization is a chemical reaction that is used to mold different solids. Since the phenolic resin is both durable and versatile, the resin can be used in making different varieties of industrial and consumer products. There is a wide range of goods that are created with the resin like kitchen appliances, billiard balls and some automotive parts as well as to construction adhesives. This material is often used in creating consumer fittings like plugs on electronic devices, handles for pans and pots and the screw-tops on bottles. The material is affordable and can be easily molded which makes the material an ideal choice for various applications.
Binder and insulator
The combination of formaldehyde and phenol is also frequently used as a compound that binds together composite woods including plywood and chipboard. When the material is applied this way, it can be somewhat brittle. It also produces very little smoke when it catches with fire and at very high grades, the material can resist temperatures even up to 370 degrees Fahrenheit. In the industry of construction, the phenolic foam made using the compounds is often used as insulation in the form of rigid sheets. This particular type of insulation is chosen for its easy installation, thermal mass as well as affordability.
As a laminate
Sheets of paper, different kinds of clothing material like cotton and linen, and glass fabric can all be treated with phenolic resin and then pressed and consequently heated in order to form hard and laminated plastic sheets. This particular composite laminate is strong, water proof and heat-resistant. The flat plates can be easily shaped and carved and are frequently used on counter tops, tables and even as pick guards for guitars.
Phenols in organic chemistry
Any member in the class of organic phenols can be referred to as phenolic compound. The compounds in this particular class are hydrocarbon groups which are similar to alcohols. The phenolics are varied and are usually found in a wide range of natural things from capsaicin (the heat agent in peppers) to neurotransmitters in the human brain.
Phenols are found in several plants including vegetables and fruits. Their antioxidant properties will help protect cells from death and damages. These substances are also found in foods like olive oil and in dietary nutrients like Vitamin E.
