phenolic resin, often used in the manufacture of plastics, adhesives and coatings and other industrial materials. This sap is a thermoplastic resin whose name is derived from its two hydrophilic aldehyde groups and one hydrophilic phenol group. It is also a colorless and transparent non-crystal with strong physical and mechanical properties. Phenolic resin modified materials can work at high temperatures and are very resistant to corrosion, and have a wide range of applications in many fields.

the characteristics of phenolic resin:

phenolic resin is made by the reaction of phenol and formaldehyde through an alkali catalyst. It has the advantages of heat resistance, chemical resistance, good hardness, high density and high transparency. As the current state of the art improves, modified phenolic resins can be made into a variety of different color materials, and their mechanical properties and corrosion resistance are superior to traditional phenolic resins. Manufacture of

phenolic resin:

polar solvent is one of the solvents of phenolic resin. Colorless and transparent, easy to operate and handle is its advantage. The manufacturing process of phenolic resin usually needs to use raw materials such as sulfuric acid, formaldehyde aqueous solution and phenol solution, and through some process to make phenolic resin.

applications:

phenolic resins are mostly used in the manufacture or modification of plastics, adhesives, insulating materials and other fields. In addition, it can also be used in the electronics industry, automobile manufacturing, manufacturing aircraft and missiles.

In short, phenolic resin is a powerful resin material that has a wide range of applications in various applications. Whether in life or industrial and technical fields, phenolic resin is used. It has the advantages of strong corrosion resistance, high temperature resistance, chemical corrosion resistance, good hardness, high density and high transparency. We also need to pay more attention to phenolic resin and explore its broader application areas in the future.
