Bakelite Phenolic resins Powder are synthetic polymers formed as condensation products of phenols and aldehydes under acid conditions. The reaction forms novolac resins. These resins require a curing agent - often hexamethylenetetramine or hexa.It is milled into powder and re-mixed with Hexa.
Bakelite Phenolic resins Powder are suited to both cold and hot compression molding for the production of a range of abrasive wheels, including those utilizing glass fabric prepregs for reinforcement.
Bakelite Phenolic resin has high heat-resistance and provides strong adhesion to grain. When compared to the other heat-resistant resins, like polyimide, phenolic resin is less expensive in cost and easier to mold
than other resins.
