Conformable abrasive article comprising: a backing having a first major surface; a deformable material contacting a central portion of the first major surface; an elastic member affixed to the first major surface of the backing and together with the backing enclosing the deformable material; and an abrasive member affixed to the elastic member, wherein the abrasive member comprises abrasive particles and a binder; and methods of making and using the same.
摘要:
An embossed structured abrasive article having an inelastic dense thermoplastic film backing and a structured abrasive layer. Both the backing and the structured abrasive layer have superposed embossed features. Methods of making and using embossed structured abrasive articles are also disclosed.
摘要:
A structured abrasive article comprises a backing, a structured abrasive layer affixed to the backing, the structured abrasive layer comprising: a plurality of raised abrasive regions, each raised abrasive region consisting essentially of a close-packed plurality of pyramidal abrasive composites; and a network consisting essentially of close-packed truncated pyramidal abrasive composites, wherein the network continuously abuts and separates the raised abrasive regions from one another. The height of the pyramidal abrasive composites is greater than the height of the truncated pyramidal abrasive composites. Methods of making and using the same are also disclosed.
