Evaluation of Grinding Performance of Unsaturated Polyester Resin

Polyester resins are unsaturated resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Polyester resins are being used in different mechanical and other industrial or household items. It also helps making Fibreglass Reinforced Plastics (FRP). Grinding of this unsaturated polyester resin is often needed, and hence, suitable process conditions are to be chosen to achieve desired grindability. In the present paper, grinding performance of unsaturated polyester resin with or without applying grinding fluid using an alumina wheel has been explored. Experimental observation shows fairly good grindability of this resin with alumina grinding wheel under wet condition and with less in feed in dry condition.
