POLYURETHANE MACHINING INFORMATION

Machining of Polyurethanes: Grinding Urethanes 55A to 80A durometer can be ground successfully in an engine lathe using a tool post grinder. Use low turning speeds - below 150 rpm, with the lathe running in reverse.RECYCLING AND RECOVERING POLYURETHANES,polyurethane foams, the grinding of these materials to small particle sizes is difficult, in particular when the material is heated up during the grinding operation.Polyurethane Foam | PolyFlex Foam,Re-Bonded Foam is sometimes called Bonded foam is re-cycled foam made by grinding old foam and off-cuts from the cutting of foam into small pieces and Re-bonding them together with a bonding/adhesive agent.
