Bakelite Phenolic resins Powder are synthetic polymers formed as condensation products of phenols and aldehydes. This step-growth polymerization reaction can be either acid- or base-catalyzed. In acid, the reaction forms novolac resins. It is milled into powder and re-mixed with Hexa.
Application
Heavy-duty grinding wheels are used for cutting and grinding foundry iron in the steel industry. These grinding wheels do not need precision but need excellent heat resistance and high strength.
The resins used have high heat resistance. These resins have short flow and high hexamine content
