Foam plastic materials based on phenol-formaldehyde resins have unique physical, chemical and operational properties. They have an amazing thermal resistance, do not burn, poorly conduct heat. However, the complexity of their manufacture by classical methods makes this valuable material very difficult to obtain for industrial production. The use of microwave activation has allowed not only to reduce the time of production of this material many times, but also to significantly reduce the range of chemicals used in the manufacture of this material. The use of microwave activation made it possibl...
