Phenolic Resins: What Are They, Their Types And Applications?

 Phenolic resins are basically a category of versatile polymers that are unlike others. Even though they were in the scene from the beginning of the journey of polymers, with time they became more popular and acceptable among the users. As of now there are numerous applications, an example is the Trespa phenolic resin countertops, which are widely used in a number of laboratory facilities all across the country. These particular resins are a category of synthetic thermosetting resin that was invented by a gentleman named Leo Baekeland in the year 1907. initially, this material was named Bakelite. Interestingly, this was probably the first type of plastic that was sold commercially.

 


TYPES

Phenolic resins can be primarily categorized into two different types: novolacs and resoles. Both are capable of delivering high-temperature stability, along with high water and chemical stability. Phenolic resins are mostly dark-colored, and these resins have an incredible price-to-performance profile. Phenolic resins constitute a host of industrial/commercial products. They are primarily used n the manufacturing of circuit boards. They are also used for the production of molded products (billiard balls) and coatings (lab countertops).

APPLICATIONS

Phenolic resins, as we mentioned previously can be found in a plethora of commercial as well as industrial products. Phenolic laminates are created by impregnating (soak or saturate something with a substance) multiple layers of the base material (paper, fiberglass or carbon) with phenolic resin. After which, the resin saturated base material is laminated under specific pressure and heat level.

Paper phenolics find application in the manufacturing of electrical components such as household laminates and boards (punch through). Glass phenolics are apt items that can be used in high-speed bearing market. Phenolic micro-balloons can be used for density control. Snooker balls and other balls that can be played on table can be made by using phenol formaldehyde resin. The binding agent in regular brake pads and clutch discs also make use of phenolic resin.

A Dutch forger named Han van Meegeren added phenol formaldehyde to his oil paints before baking the finished canvas so as to fake the drying out of the paint.
