Applications

That being said, let's expand upon the applications of phenolic resin. Phenolic resin was first used in combination with paper and fabrics as insulation for electrical equipment, and it is still used today for electrical applications like circuit boards. Phenolic resin then spread to knives-specifically, knife handles-because it machines easily, polishes well, and the grip is intrinsic when wet. These knife handles used to be easily recognizable since they only came in green and black, but these days, manufacturers of knives have discovered how to create these handles with a much wider array of colors

Phenolic resin is also useful as binders in friction materials. again thanks to its high heat tolerance. These friction materials are a big part of clutch discs and brake pads-two vital components of cars that allow them to shift gears and prevent the brakes from giving out if you have to come to a quick and sudden stop.

For vulcanized products like tires, phenolic resins are used as enhancers to improve tire traction on roads, Furthermore, the resin is combined with sand to create metal casting molds and serves as a binding agent in materials like refractory bricks. One last application that must be mentioned is how popular phenolic resins are in the lumber industry. Phenolics resins are widely used in the manufacturing of oriented strand board-a wooden board similar to particle board in that it's made by adding adhesives and compressing layers of wood stranders in specific orientations, hence the name.

As we mentioned, phenolic resins are, unfortunately, pretty brittle. For this reason, the majority of phenolic resin applications must include fillers to bolster the resin's integrity. To do this, the resin and filler material is most commonly compression-molded, but can also be injection or transfer-molded resin as well. Different fillers improve different aspects of the phenolic resin. For example, cotton improves impact strength, while glass and mineral fillers further improved the heat resistance and stiffness of the resin. The processing time for these thermoset polymers typically takes longer than thermoplastics because of the exothermic chemical reaction that takes place, rather than the polymer hardening simply through cooling. If there are molded parts, then they are subject to a separate heating treatment that adds more time to the processing period. Products made in this way
