HD EdgeKleen
HD EdgeKleen PVA Brush rollers are designed to deliver superior performance in Hard disk substrate edge cleaning applications. KJF Edgekleen’s higher porosity design and higher structure stability provides better cleanliness and durability to prolong the brush’s service life. Unique pore design decreases the particle adsorption away from the rollers’ surface, to prevent the scratch of the cleaning target. Application: for 3.5” Al Hard Disk Substrate edge cleaning.
