Polyimide Bond

Polyimide is a high temperature resin, manufactured very much the same way as standard resin bond with the pressing temperature about three times that of resin bond and pressing forces as much as 5 times. 

ASA  Polyimide resin wheels offer superior thermal superiority over regular resin bonds giving enhanced grinding performance providing excellent form holding making them the best bond choice for CNC grinders.  They also offer lower power requirement translating into the ability to achieve higher material removal rates.  Dressing polyimide wheels are difficult and ASA recommends dressing polyimide products wet.

Generally poly product is manufactured up to 14” in diameter.
