Phenol Formaldehyde Resin is a polymer compound produced by the condensation reaction of phenol and aryl alkyl ether. Its CAS number is 9003-35-4. The molecular weight is 124.137 and the molecular formula is C₇H₈O₂.The appearance is yellow crystal or white powder.Its biggest feature is that it can replace a large amount of organic solvents with water during use, eliminating solvent pollution and reducing costs.
Phenol Formaldehyde Resin
Phenolic Formaldehyde Resin is a synthetic polymer material with a wide range of uses:
- Adhesive: Phenolic resin has good bonding properties and can firmly bond a variety of materials such as wood, paper, leather, metal, etc. It is often used in the manufacture of plywood, fiberboard, grinding wheel, etc.
- Coating: The coating made with it as the base material has good water resistance, acid resistance, wear resistance and insulation, and is widely used in metal and wood surface protection and decoration in the fields of construction, shipbuilding, machinery, etc.
- Plastic: It has high mechanical strength, hardness, heat resistance and electrical insulation, and can be used to manufacture various electrical parts, auto parts, daily necessities, etc.
- Composite materials: As the matrix resin of composite materials, combined with reinforcing materials such as glass fiber and carbon fiber, it can be made into high-performance composite materials for use in aerospace, automotive industry, sporting goods and other fields.
- Insulating materials: Because Phenolic resin has excellent electrical insulation properties, it is often used to manufacture insulating materials such as insulating layers, insulating boards, and insulating rods of wires and cables to ensure the safe operation of power transmission and electrical equipment.
- Friction materials: Mixed with friction performance regulators, reinforcing materials, etc., it can be made into friction materials such as automobile brake pads, clutch facings, and train brake shoes. It has good friction performance and heat resistance, and can ensure braking effect and safety.
- Casting materials: In the casting industry, it can be used to make sand core binders, which can make the sand core have good strength and disintegration, and ensure the precision and quality of castings.
