Phenolics are a class of resins commonly based on phenol (carbolic acid). Phenolics are thermosetting resins that cure through a condensation reaction producing water that is removed processing. 

Phenolic resins are used in a wide range of applications including electronics, ballistics, mine ventilation, offshore water pipe systems, aerospace, rail and mass transit. They offer extreme high temperature resistance and electrical insulation, low density, excellent durability, and easy of forming complex contours.

Additionally Molded phenolic composites offer several advantages over metals, including smooth surfaces, weight reduction and ability to damp vibration. Overall, this material can handle & perform applications that demand stiffness, chemical resistance and dimensional stability at  high temperatures.

Phenolics are the materials of choice wherever composites need to meet very stringent fire safety, smoke emission, combustion and toxicity requirements. They are inherently flame retardant  with low heat release characteristics.

As other applications, Phenolics are applied as adhesives or matrix binders in engineered woods (plywood), and are found in brake linings, clutch plates, circuit boards, and subway car panels.

Advantages
- High temperature resistance
- Creep resistance
- Excellent thermal-insulation and sound-damping properties
- Corrosion resistant
- Excellent resistance to fire, smoke, and smoke toxicity 
- Light weight

Limitations
- Natural colour is reddish brown.
- Surfaces have to be post painted to get a high end cosmetic finish.
- Parts have to be post cured at high temperature.
- Needs superior tool construction
​

Processing technologies
The best processes for producing parts with this material are:
- open moulding
- resin transfer moulding (RTM)
- Vacuum infusion
- Vacuum bagging
