- PNL Type - Medium Grade POLINOX® unmounted flap wheels and accessories consist of non-woven polyamide abrasive, into which abrasive grain is integrated.. The wide range of hardness grades and different configurations allow a variety of surface structures and roughness levels to be achieved.
Their flexibility enables them to adapt perfectly to the contours of the workpiece. For universal applications from coarse to fine grinding.. The abrasive grain is embedded in the sturdy, flexible cloth backing material by means of a resinoid bond.
POLINOX® unitized wheels and discs consist of multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. The compressed, non-woven material is bonded to a glass-fabric base.This particular bond results in non-woven products with a very good surface finish, high stock removal POLINOX® unitized discs are used for face-down grinding on variable-speed angle grinders..
