Bakelite Phenolic Resin Powder Improved Burst Resistance for bonded Abrasives

Product description


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.


Application


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.
