Product Details
Bakelite Phenolic Resin Powder with Medium Flow for Grinding Wheels
Product description
Bakelite Phenolic Resin Powder are are produced by reacting formaldehyde with phenol under acid conditions with low free phenol and narrow MWD(Molecular weight distribution ).It is novolac resin and milled into powder and re-mixed with Hexa.
Application
Bakelite Phenolic Resin Powder is used as the principal resin binder for grinding wheels. The resin affects the degree of wetting during mixing, the strength after molding, the flow and the degree of cross-link density at curing, and helps determine abrasive properties, strength, and heat resistance.The performance of powdered phenolic resin is roughly determined by the molecular weight, which directly influences flow, hexamine content, and particle size
